摘要： An improved process for the separation of carbon dioxide from the flue gas of an oxy-combustion power plant is provided. An inlet stream containing carbon dioxide and oxygen is at least partially condensed in the reboiler of a stripping column. The condensed inlet stream is then separated in a separator, thereby producing a first liquid stream and a first gas stream. The first liquid stream is then separated into a top gas stream and a bottom liquid stream in the stripping column. The top gas stream is then warmed by indirect heat exchange in the heat exchanger. The warmed top gas stream is then recycled and combined with the inlet stream.

摘要： A hybrid system which utilizes high purity oxygen from a local pipeline, which is blended with low purity oxygen from an on-site or local cryogenic distillation system, thus resulting in a blend of intermediate quality which satisfies the needs of the customer. In order to offset the operating and energy costs associated with this fairly low profit margin intermediate purity oxygen, high purity nitrogen at high pressure is simultaneously exported to the local pipeline, thereby acting as a credit to the overall system.
