Abstract

A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic equations (material and energy balances for the gas and solid in the adsorbent bed and for the gas in the inlet and in the outlet tube, plus equilibrium relation, criterial equations etc.). The model was solved numerically, using the method of orthogonal collocation for space discretization. It can be used for simulation of adsorption, desorption and TSA processes (cyclic adsorption-desorption). The simulation was used for investigation of the influence of the main process parameters and optimization of the TSA process.
