The Grangemouth refinery and petrochemicals facility is INEOS’ largest production centre. It is a deeply integrated site exploiting synergies between the refinery and the petrochemicals plants. Located 40 kilometres west of Edinburgh on a 1700-acre site, the petrochemicals facility manufactures over 2 million tonnes of chemicals products per annum and the refinery has an annual capacity of 10 million tonnes.
At the heart of the petrochemicals site are two ethylene crackers (G4 & KG), which produce the feed materials used by the other chemicals plants. The two units have an ethylene production capacity of 1 million tonnes per year between them. The G4 ethylene cracker can crack both gas and light distillate feedstocks, whereas the KG (Kinneil Gas) unit is a gas cracker using mainly ethane and propane as its raw materials. Grangemouth's ability to crack both liquid and gas feedstocks has significant commercial advantages.
The Grangemouth Refinery processes around 200,000 barrels per day of crude oil, producing more than 9 million litres of clean fuels every day. The refinery’s oil feedstock is mainly supplied by the neighbouring BP-operated Kinneil oil and gas processing plant, with an increasing proportion imported to the site via pipeline from the Finnart Ocean Terminal located 90 kilometres west of Grangemouth.
