A METHOD FOR PROCESSING A POWER PLANT FLUE GAS

A METHOD FOR PROCESSING A POWER PLANT FLUE GAS

A method and a system are provided for processing a gas stream wherein the gas stream (124) is passed through an absorption process (126) thereby forming a C02-lean gas stream (128) having ammonia therein and a C02-rich stream (129). The C02-lean gas stream (128) having ammonia therein subsequently...

Zusammenfassung:A method and a system are provided for processing a gas stream wherein the gas stream (124) is passed through an absorption process (126) thereby forming a C02-lean gas stream (128) having ammonia therein and a C02-rich stream (129). The C02-lean gas stream (128) having ammonia therein subsequently is passed to a selective catalytic reduction process (116). L'invention concerne un procédé et un système de traitement d'un flux gazeux (124), le flux gazeux passant par un procédé d'absorption (126), formant ainsi un flux gazeux pauvre en CO2 (128) contenant de l'ammoniac en son sein et un flux riche en CO2 (129). Le flux gazeux pauvre en CO2 (128) contenant de l'ammoniac en son sein passe ensuite dans un procédé de réduction catalytique sélective (116).
