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 hold 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 is significantly depends on the total gas hold up. It is shown that the gas hold up and conversion of reaction increase in uniform distribution of gas in liquid.
