摘要: 1) Monoethanol amine (MEA) and 2) a primary shown by formula (1) below having high steric hindrance are dissolved in water to form an absorbing solution, whereby CO2 or H2S satisfactorily diffused when the solution is reclaimed, amount of vapor used reclaiming can be reduced equipment for recovering H2S. R1-R3: H C1-3 hydrocarbon group, at least one R1-R3 being hydrocarbon.
