BP Sarnia Fractionation Plant (Sarnia, Ontario)

Established in 1970 by Dome Petroleum, the fractionation plant was acquired by Amoco in 1988 which was later acquired by BP following a 1998 merger.

The 380 ac. facility receives NGL (Natural Gas Liquids (derivatives of natural gas extracted during gas refining)) from Enbridge pipeline and Shell's Kalkaska pipeline and from local sources by pipeline, tank trailer and railcars, and produces propane, isobutane, normal butane and condensate.

Finished product storage consists of twenty one 2,500 barrel horizontal storage tanks and 12 salt caverns with a total capacity of about 5,027,000 barrels (799,000 m3). The caverns store ethane, propane, isobutane and normal butane. A brine displacement system is used for moving product to and from the caverns. There are seven surface brine ponds with a capacity of 6,831,000 barrels (1,086,000 m3). Condensate and synthetic crude are stored above ground in three floating roof tanks.

Bp sold a 16.5 percent interest in the facility to Provident Energy and is interested in selling its remaining interest as part of a $30 billion asset sale to help BP meet its financial obligations from the 2010 Gulf of Mexico oil spill.
