Abstract[English]
This disclosure relates to systems and methods for separating the output stream of a carbon monoxide electrolyzer. A disclosed system includes a carbon monoxide electrolyzer which uses a dual-pressure cryogenic separation system to separate the output gas stream into three portions including a hydrogen-rich vapor stream, a CO-rich stream, and a purified ethylene stream. The cryogenic separation system includes a refrigeration system, a high-pressure gas/liquid separator, an expansion valve, and a low-pressure stripping column.[French]
La présente divulgation concerne des systèmes et des procédés de séparation du flux de sortie d'un électrolyseur de monoxyde de carbone. Un système divulgué comprend un électrolyseur de monoxyde de carbone qui utilise un système de séparation cryogénique à double pression pour séparer le flux de gaz de sortie en trois parties comprenant un flux de vapeur riche en hydrogène, un flux riche en CO et un flux d'éthylène purifié. Le système de séparation cryogénique comprend un système de réfrigération, un séparateur gaz/liquide haute pression, un détendeur et une colonne de désorption basse pression.
