Title (EN) METHOD AND APPARATUS FOR SOx AND CO2 REMOVAL FROM FLUE GAS
(FR) PROCÉDÉ ET APPAREIL POUR L'ÉLIMINATION DE SOX ET DE CO2 À PARTIR DE GAZ DE CARNEAU
Abstract: front page image
(EN)The present invention relates to a method for combined SO2 and CO2 removal from flue gas, which includes removing both CO2 and SO2 in a primary fractionation column and two polishing columns, the method comprising: a) hot flue gas pretreatment, including flue gas SO3 removal by dry sorbent injection; b) compressing the treated hot flue gas by a multi-stage compressor; c) separation of CO2, SO2 and non-condensable gases; d) subjecting the CO2 and SO2 to separate polishing columns; and e) combining streams from the primary fractionation column and the two polishing columns for power recovery.
(FR)La présente invention concerne un procédé pour l'élimination combinée de SO2 et de CO2 à partir de gaz de carneau, comprenant l'élimination de CO2 et SO2 dans une colonne de fractionnement primaire et deux colonnes de polissage, le procédé comprenant les étapes suivantes : a) le prétraitement de gaz de carneau chaud, comprenant l'élimination de SO3 de gaz de carneau par injection de sorbant sec; b) la compression du gaz de carneau chaud traité par un compresseur multi-étages; (c) la séparation de CO2, SO2 et des gaz non condensables; d) le traitement de CO2 et de SO2 dans des colonnes de polissage séparées; et e) la combinaison des flux pour la récupération d'énergie.
