HOUSTON, Aug. 3 -- Frontier El Dorado Refining Co. has begun ultralow-sulfur diesel production from a new diesel hydrotreater at the company's 110,000 b/cd El Dorado refinery in Kansas. Frontier is licensing the ULSD process from Haldor Topsoe AS, Lyngby, Denmark.
The 24,000 b/d hydrotreater operates on a blend of coker diesel, FCC light cycle oil, and straight run diesel, with 15,000-18,000 b/d (63-75%) of the total throughput cracked stocks. Topsoe provided a reactor design package, catalysts, and reactor internals for this unit.
