| Abstract: | The application of high gravity in organic amine solution removing CO2 is a new breakthrough technology, and volume mass transfer coefficient (KGa) is one of the important parameters to measure performance of packed bed.The packed bed gas liquid volumetric mass transfer model is built, and the mathematical expression of volumetric mass transfer coefficient is deduced.The experimental platform is set up to explore the rotor speed, gas flow rate, absorption liquid flow rate, temperature change on the influence of the volumetric mass transfer coefficient of the gas and liquid.The experimental results show that the appropriate conditions to improve the volumetric mass transfer coefficient between gas and liquid (KGa) is very important. |
