Simulation of nonisothermal pressure swing adsorption.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1983
Nonisothermal pressure swing adsorption is simulated by numerical calculation, by accounting for mass transfer as well as heat transfer in the column, where linear driving force for adsorption rate and linear isotherm were assumed. 40 cycles of PSA operation from start-up are iterated in the computer as a case study of air drying by activated alumina ...
