ABSTRACT:
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.
