Title
(EN) A METHOD AND SYSTEM FOR REMOVING CONTAMINANTS FROM A GAS STREAM USING A LIQUID ABSORBENT
(FR) PROCÉDÉ ET SYSTÈME D'ÉLIMINATION DE CONTAMINANTS D'UN FLUX DE GAZ À L'AIDE D'UN ABSORBANT LIQUIDE
Abstract
(EN)
Embodiments described herein provide methods of operating a linear contactor for absorbing contaminants from a gas stream. The gas stream flows from a first end to a second end of the linear contactor. Fresh absorbent is provided at the first end of the linear contactor based on the theoretical minimum amount of absorbent needed to remove the contaminants. Absorbent is recycled from the second end to the first end of the linear contactor. Fresh absorbent is provided at the second end based on chemical condition of the recycled absorbent. Apparatus for practicing the method is also described.

Des modes de réalisation de la présente invention concernent des procédés de fonctionnement d'un contacteur linéaire pour absorber des contaminants d'un flux de gaz. Le flux de gaz s'écoule d'une première extrémité à une seconde extrémité du contacteur linéaire. Un absorbant frais est disposé au niveau de la première extrémité du contacteur linéaire sur la base de la quantité minimale théorique d'absorbant nécessaire pour éliminer les contaminants. Un absorbant est recyclé de la seconde extrémité à la première extrémité du contacteur linéaire. Un absorbant frais est prévu au niveau de la seconde extrémité sur la base de l'état chimique de l'absorbant recyclé. Un appareil pour mettre en œuvre le procédé est également décrit.
