Koa will install a double combustion version of the process at its 80,000 b/d Osaka refinery and upgrade the Claus sulfur recovery unit, increasing sulfur recovery to 90 metric tons/day from 60 metric tons/day. The upgraded unit will treat hydrogen sulfide formed in removal of sulfur from heavy oil, light oil, and kerosine.
