Abstract:

The general objective of the project is fundamental mathematical modeling of a complex TSA system with electrothermal desorption step, with adsorbers assembled of one or more activated carbon fiber clot ACFC cartridge-type, radial flow fixed beds and with in-vessel condensation of the desorbed vapor. During the first stage of the project, a mathematical model of a single cartridge without condensation was developed and used for simulation. the objective of this, second stage of the project, is to model the complete TSA system, for adsorbers with one and more cartridges. Besides the material and energy balances, these models have to include the momentum balances, in order to define the complex gas flow in the complex geometry of the adsorber. The models have to describe adsorption, electrothermal desorption and electrothermal desorption accompanied with condensation of the desorbed vapor, as well as the complete TSA cycle. These models will be used for prediction of the velocity, pressure, concentration and temperature profiles in the adsorbers and calculation of the mass of condensed liquid and used electric energy. Applicability of the developed mathematical models for optimization of the TSA process, with regard to the separation and purification factor, regeneration of the condensed vapor and used energy, will also be investigated.
