Abstract
According to the lower selectivity of MEA for H 2S and the higher energy consumption in the desulfurization process, a test of selectivity and efficient of MEA, MDEA and their mixtures for H 2S has been completed. The experimental results show that the absorption efficient of DS3 # for H 2S is more than 96% and the absorption efficient for CO 2 is below 40% by using the suitable gas liquid ratio.
