| 摘要 |
The invention relates to an apparatus for compressing and/or cooling and purifying a feed gas that is rich in carbon dioxide and contains water and impurities and at least one other component, wherein said apparatus includes a compressor (C) and/or a cooler, means for delivering the feed gas into the compressor, means for recovering the water (H), contained in the feed gas, condensed during the compression, a unit (E) for purification by adsorption containing adsorbent beds (E1, E2), means for delivering the compressed feed gas to the purification unit in order to produce a compressed and dried feed gas, a unit for purification at sub-ambient temperature (CPU), means for delivering the compressed and dried feed gas (7) to the purification unit, means for extracting a fluid enriched with carbon dioxide (10) from the purification unit and means for mixing a gas (13) that has been used as a regeneration gas of an adsorption bed with at least one portion of the condensed water. |
