Meso-scale CFD Modelling of CO2 Capture by Aqueous Ammonia Part II: Parameter Analysis

Abstract

On the foundation of the study on the CFD modeling in the Part I, the various operating conditions including liquid inlet flow, gas inlet flow, CO2 inlet mass fraction, ammonia concentration and pressure on CO2 capture process are examined in this paper. The modeling results are found to be consistent with the reported experimental results on CO2 absorption rate at different operating parameters, which verifies the feasibility of the model. Meanwhile, the comparison provides a reliable basis for the optimization of process parameters.
