Work at Chevron’s 260,000 b/d El Segundo, California, refinery to replace aging coke drums has shored up pricing for midsulphur petroleum coke on the US west coast, helping it remain steady in the face of waning demand from China. Chevron said in February 2013 that it would early this year replace drums at its 3,600 t/d coker that had reached the end of their service life. The work, which began in May, should last for about three months and reduce the refinery’s coke production by about half to roughly 60,000t/month, one trader said. The refiner produces coke with a little less than 5pc sulphur.
