Petroleum coke may be stored in a pile near an oil refinery pending sale. One example, as of 2013, was the large stockpile owned by
Koch Carbon near the
Detroit River which was produced by a
Marathon Petroleum refinery in
Detroit which began refining
bitumenfrom the
oil sands of
Alberta in November, 2012. Large stockpiles of petcoke also existed in Canada as of 2013. China and Mexico were markets for petcoke exported from California to be used as fuel. As of 2013 the
EPA was declining permits to use petcoke as fuel in the United States but markets existed in India and Latin America where it was used to fuel cement manufacture. As of 2013 Oxbow Corporation, owned by
William I. Koch, was a major dealer in petcoke, selling 11 million tons annually.
