Williams Cos., Tulsa, has awarded a preliminary engineering contract for its proposed Canadian propane dehydrogenation (PDH) plant to Fluor Corp., Irving, Tex.
The plant under study would be near Redwater, Alta. It would use propane recovered from Williams’s fractionator there and convert it into polymer-grade propylene.
Williams announced last year it was considering the plant (OGJ Online, July 20, 2012). At that time, Williams said the PDH unit would have a capacity of about 1 billion lb/year and cost $600-800 million.
