A process and apparatus for removing hydrogen sulfide from high pressure gas and recovering liquid sulfur, which includes reacting the H2S with sulfite ions and an acetic acid-acid salt buffering system in an aqueous stream whereby liquid sulfur is formed, producing an effluent gas stream containing residual H2S and an effluent aqueous stream containing the liquid sulfur, extracting the residual H2S from the gaseous effluent stream, and using the extracted H2S as well as H2S recovered from the effluent aqueous stream as a source of sulfite ions for circulation to the reaction step, and as a source for additional liquid and solid sulfur. Apparatus and methods are also disclosed for recovering solid sulfur from a gaseous stream containing gaseous sulfur by contacting the gaseous stream with sulfur particles in a fluidized bed.
