Abstract

Water is a precious source. The need for analysing systems that may serve as stand-alone measuring systems is increasing for water analysis. Various advanced analytical techniques with various sensing methodologies have been described and discussed in detail in the chapter. There are presently few commercially accessible total water analysis devices that also meet the requirements for on-site assessments of different contaminants. Various spectroscopy techniques, including various fundamental methodologies, are also discussed. The testing domain includes physical, chemical and biological components responsible for environmental and human health toxicity. Some of the described promising approaches are presented in the works, and many of them already have the potential to lead to reliable and sensitive measuring systems.

Improvement Of Syngas Quality In Fixed Bed Gasifier Using Camg(CO3)2 Catalyst

Journal

This research investigates the catalytic effect of activated charcoal, MgCO3, and ZSM-5 in a batch-pyrolysis reactor with a Low-Density Poly-Ethylene (LDPE) feedstock on pyro-oil yield. Initially, trials with the ZSM-5 catalyst were conducted at various temperatures ranging from 300 to 600 °C, in which 500 °C temperature offered a higher pyro-oil yield. Further, similar experiments were carried out with activated charcoal and MgCO3 at 500 °C. The qualitative and quantitative analysis of pyro-oil was done using GC/MS, DSC, TGA, and FTIR techniques. In GC/MS and FTIR, the range of hydrocarbon lying in C5 – C35 for aliphatic, aromatic, and phenolic groups. Moreover, the thermal stability of pyro-oil is found to be 350 °C and decreased by 10%–450 °C from TGA studies. The elemental analysis of char (C90.08% H9.82% N0.10%) and gas composition of pyro-gas were also studied. Additionally, thermal calculations were done for mass balance, energy balance, and exergy balance at various temperatures and found to be in good agreement with the input and output parameters. As per findings, the pyrolysis studies at 500 °C with LDPE feedstock and ZSM-5 catalyst showed higher pyro-oil yields than other tested catalysts under similar conditions.

Abstract

This paper deals with the experimental investigations and thermodynamic studies carried out for five distinct temperatures ranging from 300 to 500 ℃ with a heating rate of 10 ℃/min. This work aims to study the influence of pyrolysis temperature on product (biochar, bio-oil, syngas) yield, its physicochemical properties and energy yield. The experiments were conducted in a batch-type vacuum pyrolysis reactor with sawdust as a feedstock. Findings show that biochar yield declined with temperature rise, whereas bio-oil and syngas yield increased. A higher yield of bio-oil (40.67%) was obtained at 450 ℃; after that it was declined. However, a higher biochar yield (60.67%) was attained at 300 ℃. Syngas generated at 500 ℃ had a higher product yield (24%) and energy output (147.05 kJ). Although, total energy output was found to be higher at 500 ℃ (634.71 kJ). This research also included thermodynamic studies such as mass, energy, exergy analysis, and sustainability analysis and found good agreement between input and output parameters. The study’s main conclusion is that higher pyrolysis temperatures (450–500 ℃) offer better results in terms of higher product and energy yield for sawdust feedstock.

Abstract

Dye-Sensitized Solar Cells (DSSCs) or Grätzel cells have attracted widespread attention due to their low cost, ease of fabrication, and reasonably good photochemical conversion efficiency. The photochemical efficiency of solar cells mainly depends on their design, development, electrodes, and electrolyte used. The use of conducting polymers in solar cells helps in reducing the cost of DSSCs with the same efficiency. Polyaniline acts as a promising conductive polymer mainly used as a counter electrode catalyst on FTO glass as well as on flexible substrates. It allows large-scale mass production and significant cost savings in the manufacturing of solar cells. This paper reviews the feasibility of Polyaniline and its composites as a counter-electrode catalyst for DSSCs. Its application as hole conductors, a catalyst for photosensitized electrolytes. The mechanism of its photocatalytic activities is well explained. The Polyaniline and Polyaniline based solar cells shows the efficiency from 7.1 to 12% with different dyes and electrolyte solutions. The recent advances made with this polymer, a suitable replacement for platinum, is also intensely reviewed.

Title of PaperEffect of Physical Properties of Synthesized Protic Ionic Liquid On Carbon Dioxide Absorption Rate

Abstract

The concentration of carbon dioxide gas has accelerated over the last two decades which cause drastic changes in the climatic conditions. In industries, carbon capture plants use a volatile organic solvent which causes many environmental threats. So, a low-cost green absorbent has been formulated with nontoxicity and high selectivity properties for absorbing carbon dioxide gas. This paper contains the synthesis process along with the structure confirmation using 1H NMR, 13C NMR, FT-IR, and mass spectroscopy. Density, viscosity, and diffusivity are measured at different ranges with standard instruments. The kinetic studies were also conducted in a standard predefined-interface stirred cell reactor. The kinetic parameters were calculated at different parameters like agitation speeds, absorption temperature, initial concentrations of ionic liquid, and partial pressure of carbon dioxide. The reaction regime of carbon dioxide absorption is found to be in fast reaction kinetics with pseudo-first-order. The reaction rate and the activation energy of CO2 absorption are experimentally determined in the range of 299 to 333 K with different initial concentrations of ionic liquid (0.1–1.1 kmol/m3). The second-order rate constant and activation energy of carbon dioxide absorption in the synthesized ionic liquid is found to be 9.48 × 103 m3 mol−1 s−1 and 16.61 kJ mol−1 respectively. On increasing the viscosity of the reacting solvent, the diffusivity of CO2 gas molecules decreases, and thus the rate of absorption decreases. This solvent has shown great potential to absorb CO2 at a large scale.

Abstract

In every chemical process industry, solvent plays a very important role mainly, in separation, by extraction, and also as a reaction intermediator, and promoter. The conventional organic solvents still in use in many industries are volatile organic compounds (VOCs) which are responsible for environmental pollution and health hazards to public. Replacing, reducing and restricting their use is one of most important initiative to be taken. Extensive research on alternate solvents and processes which are environmentally benign is the need of the day. Some of these are ionic liquids, natural extracts like plant sap, ester based, renewable feedstock-based solvents etc., and supercritical fluids (SCFs) which do not release toxic vapours into the atmosphere. Supercritical fluids which have low tunable densities varied between those of gas and liquid phases in critical conditions have been extensively studied for the past two decades to study their fundamental properties as solvents. By changing the density of the fluid, their solvation power can be tailored. These SCFs are comparatively chemically inert, eco-friendly, low-cost and have critical point under ambient conditions. Supercritical water (scH2O) has been used as an industry-attractive approach for catalytic reactions in aqueous biphasic systems. Similarly, in the sense of green chemistry and catalytic applications in various mono and biphasic systems, supercritical carbon dioxide (scCO2) is an important reaction medium. This chapter will mainly focus on green supercritical fluids solvents, solvents extracted from plants, ester solvents and briefly on room temperature ionic liquids. The content includes phase diagrams of these solvents, description of physicochemical properties and their dependence on temperature and pressure conditions, and finally their applications in different processes.

Abstract

Fine particles are in great demand in the pharmaceutical industry due to their versatile applications. Liquid antisolvent crystallization (LASC) is one of the promising approaches to prepare fine particles without requiring high energy. The interdependence of system thermodynamics, mass transfer kinetics, and the multi-phase hydrodynamics in the liquid antisolvent crystallization process is not well understood. In this review, the different modeling aspects of LASC are described from a fundamental perspective. The system thermodynamics of LASC is discussed and several models used in literature to predict the solubility in pure solvents and binary solvent mixtures are summarized. A detailed description of supersaturation, metastable zone width and induction time in antisolvent crystallization are presented and critically analyzed. The nucleation and growth kinetics are discussed and interpreted in terms of process variables. The hydrodynamic aspect of LASC which involves the mixing at different length scales is discussed and analyzed in detail. The CFD simulation-based approach to describe the interaction among different phenomena is critically reviewed. The crystallization scale-up, which is a major challenge in the LASC process, is discussed. A guideline for crystallization scale-up using the CFD-based modeling approach is presented which will be helpful to prospective researchers.

Abstract

In this article, we have proposed a kinetic model of a 2-phenyloctane formation from benzene and 1-octene in the presence of Y zeolite CVB760 solid acid catalyst. The typical elementary reaction involved in benzene alkylation consists of isomerisation of π-bond of 1-octene and attachment of octyl ion with benzene. Here, we have followed transition state theory and statistical thermodynamics to express the rate expression for the disappearance of 1-octene and formation of 1-octene and 2-phenyloctane isomers. In transition state theory, we have incorporated a single-event concept to account for a change in the relative position of the atom during the chemical reaction. Subsequently, we also estimate activation energies involved in the kinetic model using the regression method and experimental data. For this, a particle swarm optimisation (PSO) followed by Levenberg–Marquardt algorithm, called hybrid PSO, is adopted to measure the activation energies. The statistical methods involved in this investigation include analysis of variance, F-test and parity diagram and comparison between the proposed kinetic model and experimental data confirm the kinetic model reliability and optimal estimate of activation energies.

Published YearFebruary 2022

Abstract

Taylor finger is characterized by a single elongated air bubble that grows upward during the drainage of liquid from closed top vertical tubes. The characteristic of the Taylor finger is similar to the Taylor bubble commonly observed in gas–liquid two-phase flow. During the upward growth of the Taylor finger, liquid from the tube drains as a thin film around it. The exact prediction of film thickness is important in several engineering designs and process calculations such as the design of contacting devices, two-phase flow through porous media, boiling in tubes, and monolith reactors. The present study proposes an experimental technique to estimate the thickness of the draining liquid film. Based on experiments an empirical model has been proposed for non-dimensional film thickness in the inviscid region. The proposed model agrees well with the experimental data and equation proposed in published literatures (Davies, R. M., and G. Taylor. 1950. “The Mechanics of Large Bubbles Rising Through Extended Liquids and Through Liquids in Tubes.” Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences 200, 375–90; Dukler, A.

The paper discusses the formation and characteristics of stratified air–water downflow in the mesodomain. The stratified pattern, observed at low phase velocities, is characterized by air and water flowing side by side and both wetting the conduit wall, similar to stratified distributions in horizontal conduits. Such flow segregation without the influence of gravity is counterintuitive and no detailed investigation on the formation and flow physics of this distribution is reported till date. We have performed extensive experiments in glass conduits of 2.5–12.5 mm diameter where the two phases are introduced through T and Y junctions with different included angles between the entry arms. Our experiments reveal that stratified flows are formed up to a critical angle ?? subtended by the edges of the circumferential liquid film and beyond the critical wetting angle, the flow pattern is annular with liquid completely wetting the conduit wall. We further note ?? to depend on liquid properties, included angle of Y-entry, conduit diameter, and phase flow rates. Based on experimental observations, we propose a simplistic analysis to relate the liquid properties, conduit dimension, and Y-entry included angle and the liquid and gas flow rates to describe the formation of stratified and annular flow at the junction. The analysis also estimates the in situ void fraction during stratified gas–liquid downflow.

Abstract

The present paper investigates void fraction and pressure drop characteristics of vertical air-water downflow through millichannels (0.83 ≤ Eotvos Number ≤ 20.6). Experiments have revealed the hydrodynamics to be a function of tube diameter and phase velocities with the functional form being different for different flow patterns. Accordingly, separate mechanistic models have been proposed to predict the aforementioned parameters for bubbly, slug, falling film and annular flow distributions. The proposed analysis have been validated with experimental results of the present study and those reported in literature

Abstract

The present report studies on the flow pattern transitions during vertical air water downflow through millichannels (0.83 ≤ Eötvös no. ≤ 20.63). Four basic flow patterns namely falling film flow, slug flow, bubbly flow, and annular flow are observed in the range of experimental conditions studied and their range of existence has been noted to vary with tube diameter and phase velocities. Based on experimental observations, phenomenological models are proposed to predict the transition boundaries between adjacent patterns. These have been validated with experimental flow pattern maps from the present experiments. Thus the study formalizes procedure for developing a generalized flow pattern map for gas‐liquid downflow in narrow tubes.

Abstract

Biodegradation studies on Dye wastewater (DW) are normally conducted on simulated wastewaters or aqueous dyes solutions supported by growth medium, and often, an easy carbon source such as glucose. This rarely resembles actual DW which is characterized by the presence of complex organic compounds, and a high concentration of Total Dissolved Inorganic Salts (TDIS).

Heavy metals, such as, cadmium, lead, nickel and zinc can be removed from water using sorbents. The rate and extent of removal may be enhanced by choice of appropriate sorbents. In this study heavy metal sorption was studied on indigenously synthesized carbon nanomaterials (CNMs). Two CNMs differing in surface morphology were synthesized using turpentine oil in a chemical vapour deposition (CVD) setup by varying the process parameters. Activation and catalyst removal were achieved by post-treatment with HNO3 and KOH. Characterization of the CNMs produced revealed that both comprised of graphitic amorphous carbon, however, while the nanocarbon (NC) produced using cobalt catalyst in N2 atmosphere comprised of varying grain sizes indicative of soot, the nanoporous carbon (NPC) produced using silica catalyst in H2 atmosphere had a distinctive uniformly porous surface morphology. Comparative sorption studies with cadmium, lead, nickel and zinc also revealed greater sorption on NPC compared to NC. Batch isotherms for the various heavy metals using NPC and a commercial activated carbon (AC) widely used for metal sorption revealed that NPC is characterized by significantly higher metal sorption capacity and more favourable sorption energetics. The superior performance of NPC as a sorbent may be due to its unique nanoporous structure.

Abstract

Controlling industrial effluent and treating it with improvised technologies continues to be a dominant research topic in the scientific community. In this study, the concepts of circular-economy and control-of-waste-by-waste were applied to the synthesis of a photocatalyst composite composed entirely of waste resources, namely waste rust (Fe2O3) and seashells (CaO). The ratio of these two waste materials was optimized to yield a composition 10% Fe2O3/90% CaO (10-FC) that was effective in decolorizing 85% of methylene blue in 60 min, with a formal quantum efficiency of 0.27% in direct sunlight. The heterogeneous photocatalyst was characterized by UV–Vis/NIR, SEM and XRD and is proposed to follow Langmuir-Hinshelwood kinetics and Z-scheme mechanism of charge transfer. Here, waste products were integrated and utilized to create a resource that is recommended for the treatment of dye effluent using a renewable energy source. This research aims to identify elements present in waste dumps and create a valuable resource from them to promote sustainable practices.

Abstract

Additive manufacturing is an emerging technology supported by ‘Industry 4.0’. When combined with a stimulus-responsive behavior, incorporating the fourth dimension of time, it results in a manufacturing technique known as four-dimensional (4D) printing. 4D-printed entities have the distinctive characteristic of property transformation, under the influence of a drafted stimulus, which can be cleverly engineered for the desired application. The conventional stimulus-driven smart printing inks deployed in 4D printing are non-biodegradable polymers that pose a challenge to sustainability. Hence, it is imperative to appraise the utilization of sustainable raw materials, composed of natural and synthetic biodegradable polymers, as feedstocks for 4D printing. Natural resources have fluctuating properties, which make them receptive toward intelligent engineering. This review is an effort toward the implementation of sustainable feedstocks as printing inks for 4D printing, for eventual environmental benignity. It covers several sustainable raw materials for 4D printing and the strategies to use them in conjunction with conventional inks in order to bring down the volume of non-biodegradables. This review can serve as a reference for designers and engineers wishing to use sustainable inks for 4D printing, thereby boosting the momentum needed to consolidate this next-generation technology in line with the UN Sustainable Development Goals.

Abstract

In this study, a series of hybrid Ag2CO3/ZnO composites were synthesised via a simple precipitation route and investigated for discolouration-degradation of Methylene Blue and disinfection of Escherichia coli in natural sunlight. It was observed that the photonic efficiency of discolouration was more than 6 times that of the conventionally popular TiO2, under experimental conditions; 100% Total Organic Carbon reduction was observed in 30 min and 32% disinfection in an hour. This upswing in the performance is attributed to favourable modulation of the dynamics of charge transfer. The photocatalysts were characterized by X-Ray Diffraction, Scanning Electron Microscopy, Transmission Electron Microscopy, Brunauer, Emmett and Teller and Ultraviolet–Visible-Near-InfraRed Spectroscopy. An equitable photocatalyst functional mechanism has also been proposed on the basis of Tauc plot and scavenging experiments. The effect of influencing parameters has also been investigated and reported in terms of photonic efficiency. Since the entire study is carried out in direct sunlight, it inherently supports realizable solar energy applications in wastewater treatment.

In certain applications plastic materials are getting irradiated while in end use. High energy irradiation leads to the auto-oxidation and degradation. The primary approach for stabilization against post irradiation degradation is to use appropriate stabilisers. In this research work, an experimental analysis of the effect of dose rate of gamma irradiation on epoxy resin based samples prepared by using combinations of primary and secondary stabilisers is presented. The chemistry, reaction mechanisms and morphology changes are studied and its effect on mechanical properties is observed. The results show an improvement of mechanical strength as dose increases, indicating cross-linking over oxidative degradation.

Abstract

Water is the lifeblood of the environment, essential to the survival of all living things and everything must be done to maintain its quality for today and the future. Water quality is a characteristics of water, usually in respect to its suitability for a particular purpose. Acceptable values for each of these parameters depend on the use,not on the source of the water and hence the quality of the water determines its uses.Each designated use has a unique set of water quality requirements. Therefore water fit for one use may be unfit for another. Scientists are interested in specific aspects of water quality. From technical point of view,quality is determined by the kinds and amounts of substances dissolved and suspended in the water and what those substances do to inhabitants of the ecosystem. Years ago,in fact, all the way back to the beginning of the earth, nature was using natural polymers to make life possible.In this book it is discussed about development of a grafted starch based biodegradable polymer flocculant to gain both the advantage of natural as well as synthetic polymer, for the industrial waste water, which can make our environment clean.

Abstract

The active learning integrative approach of simulation-based exercises along with the core course would help undergraduate students with more engaged learning. The present study describes the simulation approach using an open-source process simulator with the help of three simulation-based exercises. The first one exemplifies the importance of the selection of an appropriate fluid package. The second exercise presented in the study shows the effect of using optimized and default values of binary interaction parameters on VLE prediction of alcohol-ester systems. The small interactive simulation-based problems with expected outcomes were presented in the third exercise which makes the learning more engaging and interesting. The current study highlights an integrative approach to inculcating critical thinking and self-learning abilities using small simulation-based exercises while learning chemical engineering thermodynamics. Finally, a survey with closed- and open-ended questions was used to gather the opinions of students on the presented exercises. A short communication is needed that sheds light on the integrative approach of learning process simulation complementing the thermodynamic theory learning.

Abstract

In the present work jatropha, palm, and karanja-based biodiesel and diesel blends, as well as biodiesel diesel and butanol blends, were studied. 112 density data for biodiesel-diesel blends in the temperature range of 30–65 °C were generated. 651 data for viscosity for these blends were generated in the temperature range of 25–65 °C. Blends with butanol were studied only at room temperature. The addition of butanol has not made much of a difference in the density or viscosity of the blends. Empirical models available in the literature were fitted to the data. The linear model in volume fraction and temperature was accurate for density. A generalized model was proposed representing the density for the biodiesel/diesel blend comprising all three biodiesels. A new empirical model for viscosity was also proposed in the study. The proposed model performed well compared to other models, with % an OARD of 3.74 %. A generalized model for viscosity was also proposed. The generalized models could estimate the density and viscosity with % OARD of 0.673  and 5.25 %, respectively.

Abstract

Biodiesel is a promising alternative to conventional fuels. Research on biodiesel has vast experimental findings, but the outcomes are not always unidirectional. The sequence of unit operation for various transesterification processes is studied. The review work emphasizes on the separation and purification of Jatropha‐derived biodiesel. The study on the downstream processes of alcohol recovery, glycerol‐rich and biodiesel‐rich phase separation, and biodiesel purification techniques is the main part of this paper. The biodiesel purification includes wet and dry washing and membrane techniques. The purpose of the review is to find separation techniques that are less energy‐intensive and environmentally friendly purification processes for biodiesel production from Jatropha. The strategies to reduce the cost of biodiesel production from Jatropha are discussed. The Jatropha biodiesel possesses huge potential as one of the alternative energy sources for commercial exploitation in India.

Abstract

Isobaric vapor–liquid equilibrium data for pure components cyclopentyl methyl ether (CPME) and cyclopentanol (CP) and their binary mixtures was generated using a modified ebulliometer. This data has been reported for five different pressures in the range of 71.50 to 101.79 kPa. Pure component boiling points were correlated using the Antoine equation and compared with the literature data. Binary vapor–liquid equilibrium data was modeled using Wilson, NRTL, and UNIQUAC models. Deviation plots for experimental and predicted temperatures are given. UNIQUAC and NRTL model predictions showed a better fit with the experimental values relative to the Wilson model.

Abstract

Advanced oxidation processes (AOPs) gain attention for wastewater treatment due to the formation of hydroxyl radicals, which have more oxidation potential. Among all AOPs, few O3, O3/UV, O3/UV/persulfate (PS), and O3/catalyst processes were studied to degrade RB5 dye wastewater. Furthermore, the effect of various experimental parameters like ozone flowrate (30–60 LPH), initial pH (2–12), initial dye concentration (100–1000 mg/L), UV intensity (11–66 W), persulfate dosage, and catalyst dosage (0.5–1.2 g/L) was studied for degradation of RB5. Furthermore, the prepared catalyst was characterized by X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy, and BET surface area. Based on the results obtained in the study, the maximum TOC removal efficiency was 96% achieved with optimum operating parameters, 60 LPH of ozone flowrate, 7 pH, 100 mg/L RB5 concentration, and 1 g/L catalyst dosage in 80 min of reaction time using O3/catalyst process, while in O3/UV/PS process, the total organic carbon (TOC) removal efficiency was 90% with optimum operating parameters, 60 LPH of ozone flowrate, 12 pH, 100 mg/L RB5 concentration, UV intensity 66 W, and TOC/PS ratio 1:40 in 80 min of reaction time. Finally, it can be seen that ozone-based AOPs offered an effective solution for the degradation of recalcitrant pollutants, especially RB5.

Abstract

The present work focuses on the comparative study of ozone-based advanced oxidation processes (AOPs): O3, O3/UV and O3/UV/PS to degrade synthetic wastewater containing Reactive Red 120 (RR120) dye. The effect of various parameters: pH, ozone flow rate, initial concentration of dye, persulfate dosage and UV light intensity was analyzed to assess the performance efficiency of AOPs. All three AOPs' performance was evaluated on decolorization, %TOC removal and ozone consumption. The highest degradation rate of 86.83% was achieved for O3/UV/PS, followed by 71.53% and 66.82% for O3/UV and O3 respectively. This better efficiency of O3/UV/PS is attributed to the fact that persulfate ions (S2O8 2-) upon activation produce sulfate radical (SO4 - ●), which is a powerful oxidant capable of degrading a wide variety of recalcitrant organic compounds. The study reveals that the efficiency of degradation of RR120 follows the order: O3/UV/PS > O3/UV > O3.

Abstract

An attempt has been made, in the present study, to do a comparative investigation of the efficiency of ozone based oxidation processes viz., O3, O3/UV, O3/UV/ Persulfate, for the removal of Reactive Red 120 dye in synthetic wastewater. All the adopted ozone based oxidation processes for the study were tested for the most appropriate conditions concerning varied parameters like initial pH, ozone flow rate, persulfate concentration. Removal of the dye was observed to be dependent on the type of ozone based oxidation process and their process parameters as well. The maximum TOC removal was 75% and was achieved by O3/UV/Persulfate process.

Abstract

Treatment of effluents from textile and tannery industries containing dyes has not been very successful using conventional methods like biological treatments. To overcome this problem various Advanced Oxidation Processes (AOPs) are being suggested in literature. In this paper an attempt has been made with the focus on the degradation of reactive red 120 dye in water by catalytic ozonation in the presence of titanium oxide catalyst and UV light. The removal of dye was monitored by the removal of TOC and color employing all the three processes, ozonation, ozonation/catalyst, ozonation/catalyst/UV have been investigated, and degradation efficiency order observed as ozonation/catalyst/UV > ozonation/ catalyst > ozonation. The results proved that the catalyst may be activated by UV + ozone and increases the dye degradation efficiency.

Abstract

A very stable calixarene-based polymeric chelating resin has been synthesized by covalently linking calix[4]arene-o-vanillinthiosemicarbazone through its ‘lower rim’ to Merrifield resin. It was characterized by FT IR, 1H NMR and elemental analysis. The resin was efficiently employed to separate and preconcentrate toxic metal ions such as Cu(II), Cd(II) and Pb(II) in a column prior to their determi
