Title
(EN) A METHOD AND SYSTEM FOR REMOVING CONTAMINANTS IN GAS USING A LIQUID SCAVENGER
(FR) PROCÉDÉ ET SYSTÈME D'ÉLIMINATION DE CONTAMINANTS DANS UN GAZ À L'AIDE D'UN CAPTEUR DE LIQUIDE
Abstract
(EN)
Embodiments described herein provide methods of removing contaminants from a gas, the methods including providing a feed gas to a vertical contactor; flowing the feed gas in a gas flow direction through the vertical contactor; mixing a fresh absorbent makeup with a recycled absorbent to form an absorbent mixture; providing a fresh absorbent feed to the feed gas; flowing the absorbent mixture through the vertical contactor in a liquid flow direction counter to the gas flow direction; recovering a clean gas stream from the vertical contactor; and recovering the recycled absorbent from the vertical contactor.
(FR)
Selon certains modes de réalisation, la présente invention concerne des procédés d'élimination de contaminants d'un gaz, les procédés comprenant la fourniture d'un gaz d'alimentation à un contacteur vertical ; l'écoulement du gaz d'alimentation dans une direction d'écoulement de gaz à travers le contacteur vertical ; le mélange d'un maquillage absorbant frais avec un absorbant recyclé afin de former un mélange absorbant ; la fourniture d'une alimentation d'absorption fraîche au gaz d'alimentation ; l'écoulement du mélange absorbant à travers le contacteur vertical dans une direction d'écoulement de liquide opposée à la direction d'écoulement de gaz ; la récupération d'un flux de gaz propre à partir du contacteur vertical ; et la récupération de l'absorbant recyclé à partir du contacteur vertical.
