PURPOSE: An improved optionally integrated residue treatment system is provided which is used to treat sulfur-bearing residue streams for the recovery of valuable organic components and significantly reduces capital and operating costs as a result of the improved process. CONSTITUTION: The sulfur-bearing residue treatment apparatus(60) comprises a substantially cylindrical residue treatment system having an upper flash tank section(64), a stripping vessel section(68), a lower flash tank section(74), an upper transition section(70) fluidically connecting the upper flash tank section and the stripping vessel section, and a lower transition vessel section(72) fluidically connecting the stripping vessel section and the lower flash tank section; the upper flash tank section(64) having a diameter different from that of the stripping vessel section(68); the lower flash tank section(74) having a diameter different from that of the stripping vessel section; a liquid inlet port(62) in the upper flash tank section; a vapor exit port(80) in the upper flash tank section(64); a liquid exit port(69) in the lower flash tank section; a return port(75) in the lower flash tank section(74); and an indirect heater(77), operatively connected between the liquid exit port(69) in the lower flash tank section and the return port in the lower flash tank section.
