A process is described for producing sulfur from a gas containing a large amount of hydrogen sulfide. The process involves reacting oxygen and hydrogen sulfide with cooling so that the effluent therefrom is at a temperature between 550/sup 0/ to 650/sup 0/F. Those reaction gases are reacted in a Claus reactor. The effluent gases leave at a temperature between 600/sup 0/ to 750/sup 0/F. Liquid sulfur is removed from the gases by lowering the temperature of the gases to 270/sup 0/ to 320/sup 0/F in a condenser. The gases are further treated in a liquid-vapor contractor by means of chilled water, whereby the water vapor in the gases is removed. The temperature of the gases is raised to 425/sup 0/ to 500/sup 0/F by using the hot gases entering the above condenser as the heating means. The heated gases are subjected to reaction in a Claus reactor. Liquid sulfur is removed from the effluent gases by lowering the temperature of the gases to 270/sup 0/F to 320/sup 0/F in a condenser. The cooled effluent gases can be admixed with the reaction gases from a reaction of oxygen and a gas rich in hydrogen sulfide. (8 claims)
