CA 2491163

An acid gas removal plant (100) includes an absorber (110) that provides a rich solvent (106) to two regenerators (120, 130) that independently generate a lean (122) and a semi-lean solvent (132), wherein the semi-lean solvent (132) is produced in one (130) of the regenerators using heat (140) and/or steam (276) derived from the other regenerator (120). Further heat integration is particularly contemplated with power plants in which the power plant provides high-level heat to the acid gas removal plant and wherein the power plant receives low-level heat from the acid gas removal plant.

L'invention concerne une installation d'élimination de gaz acides qui comprend un absorbeur fournissant un solvant riche à deux régénérateurs, lesquels génèrent indépendamment un solvant léger et un solvant semi-léger. Le solvant semi-léger est produit dans l'un des régénérateurs au moyen de la chaleur et/ou de la vapeur produites par l'autre régénérateur. D'une manière plus spécifique, l'invention concerne une intégration thermique supplémentaire avec des centrales électriques qui fournissent une chaleur élevée à l'installation d'élimination de gaz acides et qui reçoivent une faible chaleur de l'installation d'élimination de gaz acides.
