Abstract

The absorption process in the petrochemical industry is used to separate, purify and dehydration of hydrocarbon gases. Absorption is the process of absorbing substances from a gas compound with fluids. The absorption process is accompanied by rather significant thermal effects. In this paper, modeling and approbation of the kinetic method for calculating multicomponent gas absorption taking into account the thermal effects of the absorption process, based on the nonlocal version of thermodynamics, are considered. The proposed model provides the complete and consistent accounting for the thermal effects of gas absorption, and this will allow further study of their effect on the accuracy of determining the concentrations of components in the gas and fluid phases with a change in the consumption parameters of the contacting phases. Comparison of the results of calculations based on the proposed model with experimental data for different absorption cases shows its good operability and the possibility of practical application
