Title (EN) COMPOSITE AMINE ABSORBING SOLUTION, AND DEVICE AND METHOD FOR REMOVING CO2 OR H2S OR BOTH
(FR) SOLUTION D'ABSORPTION D'AMINE COMPOSITE, ET DISPOSITIF ET PROCÉDÉ D'ÉLIMINATION DE CO2 OU DE H2S OU DES DEUX
(JA) 複合アミン吸収液、CO2又はH2S又はその双方の除去装置及び方法
Abstract:
(EN) The composite amine-absorbing solution according to the present invention absorbs CO2 or H2S or both in a gas, and is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) an amide group-containing compound in water. By adopting this composite amine-absorbing solution, entangling in a composite manner occurs, and due to these synergistic effects, the absorbency of CO2 or H2S or both is good, the dissipation properties of the absorbed CO2 or H2S when reusing the absorbing solution are good, and the amount of water vapor from a reboiler 26 used when reusing the absorbing solution in a CO2 recovery device 12 can be reduced.
(FR) La présente invention concerne une solution d'absorption d'amine composite qui absorbe le CO2 ou le H2S ou les deux dans un gaz et est obtenue par dissolution (1) d'une monoamine linéaire, (2) d'une diamine et (3) d'un composé contenant un groupe amide dans l'eau. En adoptant cette solution d'absorption d'amine composite, l'enchevêtrement d'une manière composite se produit et, en raison de ces effets synergiques, la capacité d'absorption de CO2 ou de H2S ou des deux est bonne, les propriétés de dissipation du CO2 ou du H2S absorbé lors de la réutilisation de la solution d'absorption sont bonnes, et la quantité de vapeur d'eau provenant d'un rebouilleur (26) utilisé lors de la réutilisation de la solution d'absorption dans un dispositif de récupération de CO2 (12) peut être réduite.
(JA) 本発明による複合アミン吸収液は、ガス中のCO2又はH2S又はその双方を吸収する吸収液であって、(1)の直鎖モノアミンと、(2)のジアミンと、(3)のアミド基含有化合物とを、水に溶解してなるものであり、この複合アミン吸収液とすることによって、複合的に絡み合い、これらの相乗効果により、CO2又はH2S又はその双方の吸収性が良好であると共に、吸収液の再生時における吸収したCO2又はH2Sの放散性が良好なものとなり、CO2回収装置12における吸収液再生時に用いるリボイラ26の水蒸気量を低減することができる。
