Abstract[English]
The invention relates to a device and a method for deacidifying a gaseous effluent (EF) including acid compounds, in which the following steps are carried out: a) the gaseous effluent (EF) is placed in contact with an absorbent solution (SAR); b) the absorbent solution loaded with acid compounds (SA) is separated into a gaseous fraction (FG), a first liquid fraction (FL1) and a second liquid fraction (FL2); c) the absorbent solution (SA) and/or the second liquid fraction (FL2) is heated in at least two heat exchangers (E101A, E101B); d) a first portion of absorbent solution (SA) is diverted upstream of the first heat exchanger (E101A) and a second portion is diverted downstream of the first heat exchanger (E101A); e) the absorbent solution is regenerated so as to release the acid compounds into an outgoing gas stream, the absorbent solution depleted in acid compounds (SR) exiting the regeneration column (C102) and being recycled.[French]
L'invention concerne un dispositif et un procédé de désacidification d'un effluent gazeux (EF) comportant des composés acides, dans lequel on effectue les étapes suivantes : a) on met en contact l'effluent gazeux (EF) avec une solution absorbante (SAR), b) on sépare la solution absorbante chargée en composés acides (SA) en une fraction gazeuse (FG), une première fraction liquide (FL1) et une deuxième fraction liquide (FL2), c) on réchauffe la solution absorbante (SA) et/ou la deuxième fraction liquide (FL2) dans au moins deux échangeurs de chaleur (E101A, E101B), d) on dérive une première portion de solution absorbante (SA) en amont du premier échangeur de chaleur (E101A) et une deuxième portion en aval du premier échangeur de chaleur (E101A), e) on régénère la solution absorbante de manière à libérer les composés acides dans un flux gazeux sortant, la solution absorbante pauvre en composés acides (SR) ressortant de la colonne de régénération (C102) que l'on recycle
