15%Conventional sulfur recovery units are often plagued with reliability and operability issues that cause costly unplanned shutdowns. Based on continued innovation and hands-on owner/operator experience, UOP has developed unique sulfur recovery unit designs that are more robust, easier to operate and less prone to corrosion and failure.
Sulfur recovery takes place in a series of two steps: Claus Process and SCOT Process [3]. In the Modified Claus Process, partial combustion of H 2 S takes place to generate SO 2 that is reacted with the remaining H 2 S to recover sulfur as elemental sulfur. The Modified Claus Process, once-through burner operation, works only with acid gases ...
