Simulation of CO2 capture by aqueous solution of ammonia in shallow bubble column reactor



In this paper, CO2 capture by an aqueous solution of ammonia in a shallow bubble column reactor is investigated. A two-dimensional CFD model was used to predict liquid axial velocity, gas holds up, turbulent kinetic energy and conversion of reaction with single orifice sparger. The standard k-ε turbulence model along with two-fluid model was used for investigating the gas sparging effects on conversion of reaction in bubble column reactor with height to diameter ratio of 2. It is observed that the conversion of reaction significantly depends on the local gas hold-up. Uniform gas hold-up distribution increases the conversion of reaction, whereas more increase in the gas hold-up do not provide a uniform conversion in the radial direction of the column. For single orifice gas distributor, gas hold-up distribution is high in the column center and low near the walls; therefore, in the center of column lack of liquid phase decreases the conversion; while near the walls, the absence of gas phase reduces local conversion.
