| 20150361353 | PETROLEUM REFINERY MERCURY CONTROL - The mercury in crude oils is managed during the refining process to reduce its occurrence in refined petroleum products as well as in refinery emissions and wastes by converting the mercury, which may typically be present in the crude in elemental, ionic or combined organic (organomercury) forms, by operating the refinery on a blend of crudes comprising a mercury-containing crude of low sulfur content and a high sulfur crude.
