ABSTRACT:
A catalytic polyvalent metal redox solution can be recovered and re-used in a catalytic polyvalent metal redox solution H.sub.2 S-removal, sulfur production process by interposing a closed loop evaporator/condenser process and apparatus in the sulfur washing/filtering/recovery process and apparatus so that wash water used to purify the sulfur, and any polyvalent metal redox solution recovered from the sulfur melter are fed to an evaporator to concentrate the redox solution to a concentration capable of effective absorption of H.sub.2 S, and the water evaporated in the evaporator is condensed as pure water for use in washing and/or filtering the recovered sulfur.
