摘要： A process for the removal and recovery of carbon dioxide from a gaseous stream, in particular the removal and recovery of carbon dioxide, and optionally hydrogen sulphide, from a natural and/or synthesis gas stream. Furthermore, the present invention provides for the release of the removed and recovered carbon dioxide, and optionally hydrogen sulphide, at an elevated pressure, thereby reducing the high carbon dioxide compression costs associated with further chemical processing e.g. for underground carbon sequestration and/or for subsurface enhanced hydrocarbon recovery and/or for the manufacture of urea.
