Abstract

La présente invention concerne un absorbant pour séparer un gaz acide, lequel absorbant présente un excellent taux de dégazolinage et une excellente valeur de dégazolinage ainsi qu'un niveau élevé d'absorption pour un gaz acide y compris le dioxyde de carbone et une vitesse de réaction élevée. Un absorbant pour séparer un gaz acide selon la présente invention permet non seulement d'obtenir une vitesse et un niveau d'absorption du gaz acide plus élevés que les absorbants classiques à base de monoéthanolamine, mais également un taux et une valeur de dégazolinage plus élevés, ce qui permet d'améliorer la vitesse d'extraction de gaz acide dans des conditions opérationnelles identiques, de plus, la quantité d'énergie requise pour le dégazolinage peut être réduite.
