3-COMPONENT ABSORBENT SOLUTION, AND CO2 AND/OR H2S REMOVAL DEVICE AND METHOD

摘要

A first amine, which is a straight chain secondary monoamine, 2) a second amine, which is a cyclic secondary polyamine as a reaction accelerator, and 3) a third amine, which is an amine consisting of one selected from a cyclic amine group constituted from a secondary or tertiary amino group or a straight chain amine group with high steric hindrance are mixed to obtain an absorbent. By the synergistic effect thereof, absorption properties to CO 2 and/or H 2 S are excellent and the absorbed CO 2 or H 2 S emission properties during the regeneration of the absorbent become excellent. Therefore, the water vapor amount used during the regeneration of the absorbent in CO 2 recovery equipment can be reduced.
