“…This is also of importance for separation processes such as thermal swing adsorption (TSA) [4] or pressure swing adsorption (PSA) [5]. The involved physical adsorptions are mainly of a dispersive or electrostatic nature, depending on adsorbate molecules as well as on adsorbent surface functions and porosity [6].…”

“…The values obtained with these three methods have been discussed in the case of o-xylene adsorption and desorption onto bentonite clay in comparison with commercial silica chosen as the reference material. The choice of these materials rather than activated carbon is mainly due to the exothermic phenomenon associated with values of VOC adsorption enthalpy, usually ranging between 40 and 90 kJ.mol −1 [4,14]. This can yield to high temperature increases depending on levels of treated VOC concentration and may induce significant local warming to start combustion of either the adsorbate or the adsorbent itself, particularly if activated carbon is used [15,16].…”

Non-Calorimetric Determination of the Adsorption Heat of Volatile Organic Compounds under Dynamic Conditions

Avoiding strong chemical bonding, as indicated by lower heat of adsorption value, is among the selection criteria for Volatile Organic Compounds adsorbents. In this work, we highlight a non-calorimetric approach to estimating the energy of adsorption and desorption based on measurement of involved amounts, under dynamic conditions, with gaseous Fourier Transform Infrared spectroscopy. The collected data were used for obtaining adsorption heat values through the application of three different methods, namely, isosteric, temperature programmed desorption (TPD), and temperature-programmed adsorption equilibrium (TPAE). The resulting values were compared and discussed with the scope of turning determination of the heat of adsorption with non-calorimetric methods into a relevant decision making tool for designing cost-effective and safe operating of adsorption facilities.

“…The intensification parameters were the mass transfer, product purity, productivity, CO 2 uptake, PSA bed volume and energy efficiency. Kane et al 45 carried out an experimental and numerical simulation study for the PI of a conventional temperature-swing adsorption (TSA) process with a heat pump for the separation of dichloromethane. They applied coupling TSA with heat pump and thermal integration in their study as a PI technique with intensification parameters such as dichloromethane recovery, separation efficiency, heat and mass transfer and energy efficiency.…”

Process intensification (PI) is devoted to obtaining safer, smaller, cost-effective, environmentally friendly, energy-efficient and sustainable technologies, playing a major role in chemical process industries. Conventional technologies applied in the adsorptive separations may suffer from low selectivities, conversions and energy efficiencies; higher costs, kinetic and thermodynamic limitations related to the specific separation systems. Suitable PI techniques based on material, equipment and process development methodologies can play a major role in the proper organization of the adsorption separations. This article provides an overview of the concept of PI, starting from the history and its evolution over the years. Recent advances on the adsorptive separation applications through chemical PI are discussed with illustrative examples. Type of adsorption technology, intensification technique in terms of various intensification parameters are illustrated for a variety of adsorption separation systems. Product purity, productivity, gas uptake, recovery, separation efficiency, adsorbent property, bed volume, production yield, selectivity, energy efficiency, process cost and environmental sustainability are among the intensification parameters involved depending on the type of the separation system. The significant process enhancements achieved through PI in the examples are given. Conclusions, perspectives and future approaches are proposed with the aim for further contribution to the development of adsorption separations. Novelty statementSince the concept of process intensification (PI) has been introduced in the early 80s, a quite diverse range of definitions have been offered for PI during the years, which do not involve an exact standard definition that has been accepted commonly. Since then, PI has been a rapidly growing field in chemical process industries and generated many innovative processes, resulting in higher production yields, higher recovery, high-purity products, energy-efficient, cost competitive and environmental-friendly sustainable clean technologies. The paper aims to compile the concepts and definitions of PI proposed by different researchers starting from the first limited definitions until the more extensive recent ones. Then the recent advances on the various adsorptive

“…The design and dynamic simulation of these systems requires the knowledge of the adsorption equilibria for the system of interest, over a wide range of operation temperature and pressure. This information is used to calculate the heat of adsorption, which is crucial for the choice of working pair [17][18][19][20][21][22][23]. The results of extensive studies on the adsorption equilibrium for various adsorbate-adsorbent systems have been reported in [4].…”

The dynamic performance of cylindrical double-tube adsorption heat pump is numerically analysed using a non-equilibrium model, which takes into account both heat and mass transfer processes. The model includes conservation equations for: heat transfer in heating/cooling fluids, heat transfer in the metal tube, and heat and mass transfer in the adsorbent. The mathematical model is numerically solved using the method of lines. Numerical simulations are performed for the system water-zeolite 13X, chosen as the working pair. The effect of the evaporator and condenser temperatures on the adsorption and desorption kinetics is examined. The results of the numerical investigation show that both of these parameters have a significant effect on the adsorption heat pump performance. Based on computer simulation results, the values of the coefficients of performance for heating and cooling are calculated. The results show that adsorption heat pumps have relatively low efficiency compared to other heat pumps. The value of the coefficient of performance for heating is higher than for cooling Keywords: Desorption; Adsorption; Mathematical simulation; Heat pump; Coefficient of performance Nomenclature A -adsorption potential, J/mol E0 -characteristic energy of the adsorbent, J/mol COP -coefficient of performance COP h -coefficient of performance for heating * Corresponding Author.
