At Fawley in Hampshire, Esso Petroleum Company, Limited and ExxonMobil Chemical Limited operate one of the largest and most complex oil refining and petrochemical manufacturing sites in Europe.
The steam cracker is the starting point for many of the chemical products produced at Fawley. It takes a feedstock of heavy naphtha or gas oil from the refinery to produce basic chemical building blocks: ethylene, propene and butane.
ExxonMobil Chemical's Fife Ethylene Plant (FEP) is one of Europe's largest and most modern ethylene plants. Construction at Mossmorran, 25 miles north of Edinburgh, began in 1981 and the plant was officially opened by the Queen in 1986. It was the first plant specifically designed to use natural gas liquids from the North Sea as feedstock.
Ethylene is a basic chemical widely used in the production of everyday items such as plastic bags, milk and food cartons, washing up liquids, paints, anti-freeze, toys and car components.
Advanced Elastomer Systems Limited (AES), an ExxonMobil subsidiary, is one of the world's leading suppliers of thermoplastic elastomers (TPEs).
