(JA) CO2、H2S又はそれら双方の吸収液並びにそれを用いた装置及び方法
Abstract: front page image
(EN)The present invention provides: an absorbent liquid for CO2 and/or H2S, which is capable of reducing the amount of reboiler heat when the absorbent liquid is recycled; and an apparatus and a method, which use this absorbent liquid. An absorbent liquid according to the present invention absorbs CO2 and/or H2S in a gas, and contains, as constituents, (a) a secondary linear monoamine, (b1) a tertiary linear monoamine or (b2) a hindered primary monoamine, and (c) a secondary cyclic diamine. The concentrations of these constituents are less than 30% by weight.
(FR)La présente invention concerne : un liquide absorbant pour CO2 et/ou H2S, qui est capable de réduire la quantité de chaleur de rebouilleur lorsque le liquide absorbant est recyclé; et un appareil et un procédé, qui utilisent ce liquide absorbant. Un liquide absorbant selon la présente invention absorbe CO2 et/ou H2S présents dans un gaz, et contient, à titre des constituants, (a) une monoamine linéaire secondaire, (b1) une monoamine linéaire tertiaire ou (b2) une monoamine primaire encombrée, et (c) une diamine cyclique secondaire. Les concentrations de ces constituants sont inférieures à 30 % en poids.
(JA)本発明は、吸収液を再生利用する際のリボイラ熱量を低減することができるCO2、H2S又はそれら双方の吸収液並びにそれを用いた装置及び方法を提供する。本発明に係る吸収液は、ガス中のCO2、H2S又はそれら双方を吸収する吸収液であって、(a)2級直鎖モノアミンと、(b1)3級直鎖モノアミン又は(b2)立体障害性のある1級モノアミンと、(c)2級環状ジアミンとを成分として含み、前記各成分の濃度が30重量%未満である。
