Fawley Refinery


Fawley Refinery is an oil refinery located at Fawley, Hampshire, England. The refinery is owned by Esso, which acquired the site in 1925. Situated on Southampton Water, it was rebuilt and extended in 1951 and is now the largest oil refinery in the United Kingdom, and one of the most complex refineries in Europe. With a capacity of per day, Fawley provides 20 percent of the UK's refinery capacity. An estimated 2,300 people are employed at the site.

History

The refinery was established in 1921 by the Atlantic, Gulf and West Indies Oil Company on of land. The site was chosen because a large amount of land was available for development, and the area was not heavily populated, and because of the position on Southampton Water. This provided access to the large amount of water used in the refining process, and also made it possible for crude oil to be brought to the site in ocean tankers by sea. Proximity to Southampton was also a factor, as at the outset much of the plant's output was used to supply liners using Southampton Docks. Atlantic, Gulf and West Indies were bought out by British-Mexican Petroleum in 1923, and they, in turn, were taken over by the Anglo-American Oil Company in 1926, which was the British affiliate of Esso. In 1939 capacity was around 600,000 tonnes of crude oil per annum which met just 6.7% of UK demand. Refining ceased during World War II, when most refined oil for the UK was imported, and Fawley was used as a storage depot.
In 1949 Esso embarked on the construction of a new refinery, and a further of land were acquired. The first stage of this expansion, which came on-stream in 1951, consisted of primary distillation units, a catalytic cracker and numerous treating units. The refinery was opened by British prime minister Clement Attlee on 14 September 1951. It had an initial estimated capacity of per day, or around one third of UK demand at that time. The chemical plant was created in 1958. Additional refining capacity was added, and Fawley's capacity reached around 19,500,000 tonnes of crude oil per annum in 1973, and has since decreased, partly because of reduced demand for oil.

Esso refinery

Fawley refinery processes around of crude oil a day and provides 20 per cent of the UK's refinery capacity. Crude oil is transported by sea in tankers to the refinery's marine terminal, which handles around 2,000 ship movements and 22 million tonnes of crude oil and other products every year. The crude oil is pumped into storage tanks before being processed.
The crude oil is distilled into different fractions, with other complex processes being performed to produce a full range of products, that includes propane and butane, petrol, jet fuel, diesel, marine fuels, heating oil, lubricant basestocks and fuel oil. Major process units include three atmospheric and three vacuum distillation units, a fluid catalytic cracking unit, a resid finer, a polymerization plant, two powerformers, six hydrofiners, two sulphur extraction units, a lubricating oil manufacturing complex, an isomerization unit and a bitumen plant. In addition to this, the refinery is also home to the largest refrigerated LPG storage facility in Northern Europe.
About 5% of Fawley's production is distributed by rail or road, 25% by sea and 70% by pipelines. The refinery at Fawley also supplies feedstock to the adjacent chemical plant. Rail facilities at Fawley comprise LPG loading, chlorine facilities, crude offloading, a chemical facilities building, caustic facilities, butyl rubber, bitumen, gas oil and a coal road. The Fawley branch line is connected to the South Western main line via an east-facing connection to the west of Totton station.

Chemical plant

The site houses a chemical facility operated by ExxonMobil and Nalco.
The ExxonMobil chemical plant produces approximately 750,000 tonnes of chemical products every year. The initial stage for many of the chemical products was the steam cracker, which took a feedstock of heavy naphtha or gas oil from the refinery to produce basic chemical building blocks: ethylene, propene and butene. This plant is now demolished, with Ethylene shipped directly in from a supplier; the propene and butene streams from the petroleum side of the refinery are used as feedstocks, mainly for the higher olefins plant and the isobutylene plant. Butene is stored in seven large pressurised spheres – known as the seven sisters – that are a prominent feature of the Fawley site.
The higher olefins plant is the largest chemical plant at Fawley. The 14 higher olefins manufactured at Fawley are shipped to other chemical plants in Europe for further processing. They are used in the manufacture of plasticizers – the component in plastics which makes them flexible – and also in the manufacture of performance fluids.
The two key chemical products produced at Fawley are halobutyl rubber and methyl ethyl ketone:
The refinery can handle VLCCs up to 244,000 tonnes displacement, with a length overall up to 368 m. It has nine berths, 5 oceangoing berths with depths from 10.2 m. and 14.9 m., and 4 for coastal vessels with depths in the 5-6 m. range.

Safety record

Fawley refinery has been the scene of a number of fires and explosions.
In 1935, a major oil tank blaze caused a fire that lasted many days.
In 1969, a major fire broke out in the refinery causing damage to large parts of it.
In July 2007, the BBC reported a fire in the steam generating plant of the refinery with no casualties. It caused a major part of the refinery to be shut down for a few days.
On 20 June 2010 around 20 barrels of vacuum gas oil leaked into Southampton Water as a ship was unloaded. Esso was later fined £10,000 for the incident.
In 2008 a sailor from Honduras died after a fuel pipe fell from a refinery jib due to a corroded connecting bolt. The pipe collapsed on to the deck of the oil tanker MT Castillo de Monterreal. Esso and Austin & McLean were charged with breaching the Health and Safety Act for the accident, and were fined £100,000.
In 2011, an accident at the refinery caused the death of one of its workers.
