ABSTRACT:
Gaseous sulfur and nitrogen compounds are removed from mixed gases containing such compounds by contacting the gases with liquid organic disulfides in a contacting zone and withdrawing gases of reduced sulfur and nitrogen content. After contacting, the disulfides may be stripped of absorbed gases and then reused or instead may be converted into hydrocarbons substantially free of sulfur and nitrogen-containing constituents. The liquid disulfides are particularly effective for the selective removal of hydrogen sulfide from gases containing carbon dioxide.
