Studies on Mass Transfer Process of CO2 Absorption in Aqueous Ammonia in Packaged Column

The experimental system was established, which consists of some sub-systems, gas mixer, gas flow rate control, packed column, absorption solution. The effect of the concentrations of CO2 inlet, flow rate of aqueous ammonia, concentrations of aqueous ammonia and packing condition on KGa was experimentally investigated. Based on the measured data, KGa was determined on different conditions with the equation, which was put forward according to the characters of CO2 absorption by aqueous ammonia.
