The present invention relates to a process and plant for the recovery of carbon dioxide from a gas stream by means of pressure swing adsorption using an adsorbent, such as X or Y type Zeolite adsorbents. The gas feed stream suitably has a moderate concentration of carbon dioxide, such as gas emitted from the filling bowl of the carbonated drinks bottling plant and is recovered without rinsing or purging the adsorbent with a high purity carbon dioxide gas stream. The process therefore provides the advantage of being capturing carbon dioxide from the effluent that would otherwise be emitted to the atmosphere and captures the carbon dioxide in a manner that minimises operational and capital expenditure. The present invention also relates to a process for utilizing one dry stream from a gas separation unit (adsorption or membrane process) to conduct evaporative cooling of water, which is used as the water in a liquid ring vacuum pump thereby decreasing the vacuum level and improving the performance.

La présente invention concerne un procédé et une usine de récupération de dioxyde de carbone à partir d'un flux gazeux par adsorption modulée en pression au moyen d'un adsorbant, tel qu'un adsorbant de zéolithe type X ou Y. Le flux d'alimentation en gaz contient, de manière avantageuse, une concentration modérée de dioxyde de carbone, tel que le gaz émis par la cuve de remplissage d'une usine d'embouteillage de boissons gazeuses et est récupéré sans rinçage ni purge de l'adsorbant avec un flux gazeux de dioxyde de carbone très pur. Le procédé offre, par conséquent, l'avantage de capturer le dioxyde de carbone contenu dans un effluent qui, sinon, serait émis dans l'atmosphère et capture le dioxyde de carbone d'une manière qui minimise les frais d'exploitation et d'investissement. La présente invention concerne également un procédé utilisant le flux sec provenant d'une unité de séparation de gaz (procédé par adsorption ou par membrane) pour procéder au refroidissement de l'eau d'évaporation, qui sert d'eau dans une pompe à vide à anneau liquide, réduisant ainsi le niveau de vide et améliorant la performance.
