EDS syncrude derived from Texas Lignite (Big Brown) was refined in an extensive program which included pilot plant and laboratory studies. Then the cost of refining was estimated from engineering studies. It was demonstrated that advanced, commercial petroleum technology can be used to refine this syncrude to gasoline, jet, diesel, and heating fuels. The EDS syncrude contains less hydrogen than petroleum crudes. It also contains large amounts of heteroatom impurities. It differs from petroleum in that it contains almost no residua and over 90% boils in the gasoline and diesel ranges. With these properties, an appropriate way to refine is by hydroprocessing. Hydroprocessing yields a volume of finished products which is 88 to 97 LV% of the original volume of syncrude. In addition, the heteroatoms are ultimately removed as sulfur and salable ammonia. The engineering studies provided estimates of the refining costs for grass roots refineries which would produce 50,000 bbl per calendar day of products. The Second Quarter 1983 refining costs range from $12 to $17/bbl of product, depending upon the desired product slate. These costs do not include the cost of the EDS syncrude itself. 36 references, 17 figures, 116 tables.
