High pressure CO2 purification and supply process and apparatus |
摘要 |
A batch process and apparatus (1) for producing a pressurized liquid carbon dioxide stream includes forming a feed stream (11) of carbon dioxide vapor from a liquid carbon dioxide supply (10) by vaporisation or distillation; introducing the carbon dioxide vapor feed stream into at least one purifying filter (13,14); condensing the purified feed stream within a condenser (18) to form an intermediate liquid carbon dioxide stream (24); introducing the intermediate liquid carbon dioxide stream (24) into at least one high-pressure accumulation chamber (30); heating the high pressure accumulation chamber (30) to pressurize the liquid carbon dioxide contained therein to a delivery pressure; delivering a pressurized liquid carbon dioxide stream (43) from the high-pressure accumulation chamber (30); and, discontinuing delivery of the pressurized liquid carbon dioxide stream (43) for replenishing the high pressure accumulation chamber (30). <IMAGE> |
