Abstract

A distillation system for producing carbon dioxide, particularly from a feed which contains significant levels of light components, wherein the feed is at least partially condensed upstream of the distillation by indirect heat exchange with a multicomponent heat exchange fluid recirculating in a closed refrigeration loop, and/or the overhead from the distillation is condensed for reflux by indirect heat exchange with a multicomponent heat exchange fluid recirculating in a closed refrigeration loop.
