<p>Elemental sulfur is recovered from the H2S present in natural gas and other process gases in a reaction scheme that combines a liquid-phase reactor, a furnace and an SO2 absorber. The reactor reacts the H2S with SO2 using excess H2S in the liquid phase in the presence of a homogeneous catalyst, and the SO2 is supplied to the reactor by combusting the unreacted H2S in the furnace, recovering the SO2 from the combustion gas in an absorber and directing the recovered SO2 to the reactor. The reaction scheme produces no reaction products other than S and H2O.</p> |
