A system (10) for absorbing and thereby removing at least a portion of an acidic component from a process stream (20), the system including: an absorber (22) adapted to accept a process stream, wherein the absorber employs an absorbent solution to absorb an acidic component from the process stream to produce a rich absorbent solution (24) and a process stream having a reduced amount of said acidic component (20a); a regenerator (26) adapted to regenerate the rich absorbent solution, thereby producing a lean absorbent solution (28) and a semi-lean absorbent solution (30); a solution outlet (50) fluidly coupled to the regenerator to facilitate removal of at least a portion of the semi-lean absorbent solution from the regenerator; and a control mechanism (56) coupled to the solution outlet, the control mechanism adapted to control an amount of the semi-lean absorbent solution removed from the regenerator.

L'invention concerne un système (10) permettant d'absorber et de retirer ainsi au moins une partie d'un composant acide d'un flux de traitement (20), ce système comprenant : un absorbeur (22) conçu pour accepter un flux de traitement, cet absorbeur utilisant une solution absorbante destinée à absorber un composant acide d'un flux de traitement afin de produire une solution absorbante riche (24) et un flux de traitement possédant une quantité réduite de ce composant acide (20a), un régénérateur (26) conçu pour régénérer la solution absorbante riche, produisant ainsi une solution absorbante pauvre (28) et une solution absorbante semi-pauvre (30), un orifice de sortie de solution (50) en communication fluidique avec le régénérateur afin de faciliter la suppression d'au moins une partie de la solution absorbante semi-pauvre du régénérateur, et un mécanisme de commande (56) couplé à l'orifice de sortie de solution, ce mécanisme de commande étant conçu pour commander une quantité de la solution absorbante semi-pauvre retirée du régénérateur.
