Abstract
A multi-stage UCSRP process and system for removal of sulfur from a gaseous stream in which the gaseous stream, which contains a first amount of H2S, is provided to a first stage UCSRP reactor vessel operating in an excess SO2 mode at a first amount of SO2, producing an effluent gas having a reduced amount of SO2, and in which the effluent gas is provided to a second stage UCSRP reactor vessel operating in an excess H2S mode, producing a product gas having an amount of H2S less than said first amount of H2S.
