PROCESS FOR CARBON DIOXIDE RECOVERY

摘要

PROBLEM TO BE SOLVED: To provide a system for recovering and purifying a carbon dioxide-containing stream from a batch process tool (10).

SOLUTION: A multi-phase contaminated stream containing at least carbon dioxide and one or more cosolvent (20, 30) is removed from the process tool (10) and conveyed to at least one intermediate pressure separator (40). The contaminant-containing stream is separated into an intermediate pressure carbon dioxide-enriched vapor stream (42) and an intermediate pressure solvent and contaminant-enriched stream (43) in the intermediate pressure separator (40).
