Research of Selective H2S Removal by Methyldiethanolamine Solutions in Experimental Simulation Apparatus

Abstract:

In this research, an experimental apparatus that composed of adiabatic packed absorption and regeneration columns was established to simulate H2S removal process. The results show that the reaction between CO2 and MDEA can be regarded as a rapid pseudo-first-order reversible reaction and the CO2 absorption mainly is controlled by liquid film resistance while the reaction between H2S and MDEA are reversible instantaneous. For H2S absorption, it is mainly controlled by gas film resistance but the rate of liquid film resistance to the total resistance of H2S absorption was distributed from 25.7% (column bottom) to 12.6% (column up).
