Determination Effects of Process Parameters on CO2 Reactive absorption System by Mathematical Modeling

Abstract

A steady state model for CO2- reactive absorption system was developed based on principle of mass transfer and chemical reaction. The pseudo-first order model is assumed and reversibility of chemical reaction was also neglected. The continuity model equation in term of material balance with chemical reaction across an elemental stage K on CO2 was developed. The model consists of system of linear simultaneous equations, and the equations representing the composition of CO2 in both liquid and gas phases were solved. The simulation studies were performed to investigate the effect of changing various process variables such as number of plate, gas flow rate, and CO2 composition in the feed vapor.
