A small refinery, Eastham Refinery Ltd., was constructed at Eastham in 1966 to the east of the tank farm. This was a joint venture between Tarmac Ltd. and Phillips Petroleum of America (Phillips 66) and traded under the name of Philmac Oil Ltd. The refinery took heavy naphthenic crude as a feedstock and produced
bitumen and other distillate products such as gas oil, marine diesel, lubricating base stocks. In 1989 the unit was expanded to provide a capacity of 1.2 million tonnes per year. Briggs Oil was acquired by the Swedish firm AB Nynas Petroleum in 1992 for £70 million; Shell retained its interest in the plant. In 1992 the refinery comprised a vacuum distillation unit with a capacity of 10,500
barrels/day (1,669 m3/day) producing 8,000 barrels/day (1272 m3/day) of
asphalt. The
Energy Institute noted that the refinery closed in 2010. However, Eastham Refinery Ltd still operated a bitumen plant in 2017. The plant produces bitumen by a 2-stage distillation process using crude oil and refinery residues as feedstock. Crude oil is received by pipeline from the nearby Tranmere terminal and the residues by pipeline from the Queen Elizabeth II dock. The raw materials and product are stored in a tank farm on the site. In 2015 the plant processed 978,472 tonnes of feedstock oil. The plant uses a combination of an atmospheric distillation column and a vacuum column to separate oil into various final components. ==References==
