Scaling rules and intensification of thermal swing adsorption

Novel Thermal Swing Adsorption Process with a Cooling Jacket for Benzene−Toluene−p-Xylene Purification

“…(7) The multicomponent adsorption equilibrium is represented by the temperature-dependent extended Langmuir equation. (8) The physical properties of the gas phase are those of the feed gas. (9) The physical properties of the adsorbent and the column wall are assumed to be constant.…”

“…As for a part of the experimental and theoretical studies, the effects of the thermal wave were reported 5 and the discussions of a cooling step were addressed. [6][7][8][9] The extended researches about the regeneration were carried out. [10][11][12][13][14][15][16][17][18][19] Adsorption equilibrium data were presented for some chlorinated organic solvents (dichloromethane, 1,1,1-trichloroethane, and trichloroethylene) on activated carbon at various temperatures.…”

“…TSA has not been conventional for the bulk separation processes but has been more preferable than PSA for solvent recovery, purification, and drying. − Especially, a fixed bed of TSA has been one of the most conventional cyclic processes including adsorption and desorption steps for purifying strong adsorbates. As for a part of the experimental and theoretical studies, the effects of the thermal wave were reported and the discussions of a cooling step were addressed. − The extended researches about the regeneration were carried out. − Adsorption equilibrium data were presented for some chlorinated organic solvents (dichloromethane, 1,1,1-trichloroethane, and trichloroethylene) on activated carbon at various temperatures. , Adsorption isotherms were obtained for binary component systems such as benzene−methylbenzene vapors on activated carbon and benzene−toluene vapors on activated carbon fiber by experimental and theoretical study. In view of mathematical modeling, lots of fixed-bed models have been developed using many simplifying assumptions.…”
