Rigorous Mathematical Modeling of an Adsorption System With Electrothermal Regeneration of the Used Adsorbent

Abstract

The general objective of the project is fundamental mathematical modeling of a complex TSA system with electrothermal desorption step, with absorbers assembled of one or more cartridge-type, radial flow fixed beds and with in-vessel condensation of the desorbed vapor. During the first stage of the project, a 1-D mathematical model of a single cartridge without condensation was developed in Matlab and used for simulation. During the second stage of the project, the complete TSA system, for adsorbers with on and two cartridge, was modeled, using a combination of Femlab and Matlab software. 2-D Femlab models that describe adsorption, electrothermal desorption and electrothermal desorption accompanied with condensation of the desorbed vapor were built and integrated using Matlab, in order to describe and simulate complete TSA cycles. The objective of this, third phase of the project, is to develop mathematical models of another complex configuration, with four parallel annular, radial-flow cartridge-type adsorbers. The analysis of this configuration shows that 3-D models have to be used in order to describe it. The models for adsorption, electrothermal desorption and electrothermal desorption accompanied with condensation of the desorbed vapor are developed again, by using COMSOL Multiphysics (Femlab) 3-D modeling tools.
