摘要：Desulfurizer JPE-7, a sterically hindered amine, has higher selectivity and absorption capacities than MDEA. JPE-7 has fast and complete regenerability, which has constant and lower H2S content in the reduplicate tail gas. Thermal stability of JPE-7 is favorable for industrial operation condition. With the concentration of JPE-7 increasing, the absorption of CO2, rapidly increases, while that of H2S is reluctant to increase thus the selectivity and absorptivity is reluctant to increase. The optimum concentration of JPE-7 is range from 30 wt% to 40 wt%. The dimethyl yellow-methenyl blue method is recommended to determine the concentration of JPE-7 with reasonable accuracy.
