Abstract
A system for removing and purifying a carbon dioxide-containing stream from a batch process tool is provided. A multi-phase contaminated stream containing at least carbon dioxide and one or more co-solvent is removed from a process tool and conveyed to at least one intermediate pressure separator. The contaminant-containing stream is separated into an intermediate pressure carbon dioxide-enriched vapor stream and an intermediate pressure solvent and contaminant-enriched stream in the intermediate pressure separator.
