HOUSTON, July 11 -- Caltex Australia Petroleum Pty. Ltd., Sydney, has let a contract to Haldor Topsoe for a grassroots 3,000-tonne/day diesel hydrotreater at its 105,000 b/d Lytton refinery in Brisbane, Australia.
Haldor Topsoe will provide license, basic engineering, reactor internals, catalyst, and technical services for a unit to produce diesel with a maximum 8 ppm sulfur in 2009 as required by the Australian government.
The refinery's diesel hydrotreater unit currently is producing diesel to the new limit of 50 ppm sulfur, down from 500 ppm in 2005.
Over the past 15 months, Caltex has implemented a $250 million clean fuels project at the 41-year old refinery to reduce benzene in gasoline and sulfur in diesel this year. It has added 64 items of major equipment, 19 km of piping, and 1,000 instruments. A new benzene hydrogenation unit produces gasoline with a maximum of 1% benzene, down from 2-3%.
Caltex has completed a similar project at its 105,500 b/d Kurnell refinery in Sydney.
