<p>A process for recovering carbon dioxide from a gas mixture containing it in a concentration of at least about 40%, wherein the gas mixture is distilled at superatmospheric pressure and subambient temperature to yield substantially pure carbon dioxide as a liquid bottoms product, the distillation overhead is then warmed and subjected to membrane separation to yield a carbon dioxide-rich permeate which is returned to the distillation column.</p> |
