CrystaTech has developed a highly efficient sulfur recovery process calledCrystaSulf. Under the terms of the deal, PSN's Calgary office will co-ordinateengineering, procurement, and construction management (EPCM) work relating todeployment of CrystaSulf in Canada and selected international markets.
