Hydroprocessing of Heavy Oils and ResiduaJorge Ancheyta, James G. Speight Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional- and formerly wasted- sources.
