ABSORBING SOLUTION, AND CO2 OR H2S REMOVAL APPARATUS AND METHOD EMPLOYING THE ABSORBING SOLUTION

摘要

PPROBLEM TO BE SOLVED: To provide an absorbing solution with increased removal efficiency by remarkably increasing a removal rate of COSB2/SBor HSB2/SBS in combustion exhaust gas, and a COSB2/SBor HSB2/SBS removal apparatus and method employing the absorbing solution. PSOLUTION: The absorbing liquid absorbs COSB2/SBor HSB2/SBS in exhaust gas discharged from power generation equipment, like a thermal power plant, and contains three or more kinds of amine compounds selected from among straight chain or cyclic amine compounds having primary amino groups and straight chain or cyclic amine compounds having secondary amino group. The synergistic effect of mixing of these substances increases the absorption rate of COSB2/SBor HSB2/SBS. PCOPYRIGHT: (C)2009,JPO&INPIT
