Title
(EN) THERMAL INTEGRATION OF OXYGEN PLANTS
(FR) INTÉGRATION THERMIQUE DE CENTRALES D'OXYGÈNE
Abstract
(EN)
A process for the integration of a cryogenic air separation plant and an oxy- combustion power plant is presented. This process also includes heating a pressurized nitrogen stream (52) and a pressurized oxygen stream (54) with a compressed air stream (51) that is extracted from the air compressor of a cryogenic air separation plant (1), thereby forming a heated pressurized nitrogen stream and a heated pressurized oxygen stream. This process 'also includes burning a fuel stream with said heated pressurized oxygen stream to produce a flue gas stream, heating said heated pressurized nitrogen stream to form a hot pressurized nitrogen stream (14), then work expanding said hot pressurized nitrogen stream to a lower pressure thereby forming a hot exhaust nitrogen stream and recovering energy. And this process also includes heating said boiler feed water stream (13) by indirect heat exchange with said hot exhaust nitrogen stream.

La présente invention concerne un procédé d'intégration d'une plante de séparation cryogénique de l'air et d'une centrale électrique utilisant l'oxycombustion. Ce procédé comprend également le chauffage d'un flux d'azote sous pression et d'un flux d'oxygène sous pression avec un flux d'air comprimé qui est extrait d'un compresseur d'air d'installation de séparation d'air cryogénique, formant ainsi un flux d'azote sous pression réchauffé et un flux d'oxygène sous pression réchauffé. Ce procédé comprend la combustion d'un flux de combustible avec ledit flux d'oxygène sous pression réchauffé pour produire un flux de gaz de carneau, le chauffage dudit flux d'azote sous pression réchauffé pour former un flux d'azote sous pression réchauffé, suivi de la détente dudit flux d'azote sous pression réchauffé vers une pression inférieure formant ainsi un flux d'azote des gaz d'échappement réchauffé et une récupération d'énergie. Ce procédé comprend en outre le chauffage dudit écoulement d'eau d'alimentation de chaudière par l'échange de chaleur indirect avec ledit flux d'azote des gaz d'échappement réchauffé.
