ABSTRACT:
A process is described for the separation of carbon dioxide and sulfide gases from oil shale retorting off-gases, coal gasification off-gases, oxygen fireflooding off-gases or carbon dioxide miscible flood enhanced oil recovery off-gases for recycle to a retort, gasifier, petroleum reservoir or to further sulfide processing prior to export. The process separates the off-gases into an essentially sulfur-free light BTU fuel gas, a heavy hydrocarbon stream and a carbon dioxide acid gas stream wherein the off-gas is compressed if necessary and cooled to separate the various streams. The carbon dioxide acid gas stream is expanded in an auto-refrigeration step to provide the necessary process refrigeration. In the oil shale retort and coal gasification applications the sulfur constituents are sorbed on spent oil shale particles or coal ash.
