Abstract
Physical and mathematical simulation of the process of adsorption of gas components on the adsorbent injected into the steam-air flow in a cylindrical tube and Venturi tube was carried out. Calculated estimates of CO2 adsorption on aluminosilicate with a mass median particle size of 50 µm were carried out using the phase equilibrium coefficient found by the authors in [1] by comparing the calculated and experimental data from [2]. The analysis of adsorption process under the considered conditions is carried out and practical conclusions were made.
