Title (EN) CO2 RECOVERY AND COLD WATER PRODUCTION METHOD
(FR) PROCÉDÉ DE CAPTURE DU CO2 ET DE PRODUCTION D'EAU FROIDE
Abstract:
(EN) Disclosed is a method for producing chilled water, at least one gas having a low CO2 concentration, and one or more primary fluids having a high CO2 concentration from a fluid which is to be treated and contains CO2 and at least one compound that is more volatile than CO2, and from industrial water. Said method comprises the following steps: a) the fluid to be treated is separated into at least the gas having a low CO2 concentration (44) and the primary fluids having a high CO2 concentration; and b) the industrial water is chilled by exchanging heat with a fraction of the gas having a low CO2 concentration, said fraction not amounting to zero, such that the chilled water is obtained. The disclosed method is characterized in that the heat exchange in step b) takes place in a direct-contact tower.
(FR) Procédé de production d'eau réfrigérée, d'au moins un gaz pauvre en CO2 et d'un ou plusieurs fluides primaires riches en CO2 à partir d'un fluide à traiter comprenant du CO2 et au moins un composé plus volatil que le CO2 et d'eau industrielle, comprenant les étapes suivantes : a) séparation dudit fluide à traiter en au moins ledit gaz pauvre en CO2 (44) et lesdits fluides primaires riches en CO2; et b) refroidissement de ladite eau industrielle par échange de chaleur avec une fraction non nulle dudit gaz pauvre en CO2, de manière à obtenir ladite d'eau réfrigérée; caractérisé en ce que, à l'étape b), ledit échange de chaleur est réalisé dans une tour à contact direct.
