Low temperature Claus process with water removal
 Claus process sulfur recovery can be improved by performing a Claus conversion under low temperature and low water concentration conditions. The process treats a feed stream containing sulfur compounds by converting all sulfur compounds in the stream to a single sulfur species, reducing water content to low water concentrations, creation of a Claus reaction mixture, and then low temperature catalytic conversion to sulfur and water.
