Popis:	The reduction of greenhouse gases is an important mitigation effort in the midst of rising global temperatures. CO2 capture with absorption is chosen because this technology looks to be ready for retrofitting in the power plant. This absorption column is simulated using FLUENT v 6.3.26. The simulated absorption column is 8m in height and 1m in diameter. Specifying boundary and operating conditions (temperature, pressure, fluid flow models, flow rates and porosity) and iterations are done till all the equations converge. Also, simulations were carried out for various porosities, liquid flow rates and gas flow rates to study the effect of variation in exit CO2 concentration and optimized. The simulated column showed maximum CO2 recovery of about 90% for liquid flow rate 3.2kg/s, gas flow rate 1kg/s and porosity=0.6.
