Harwich Refinery
Harwich refinery is a 500,000 tonnes per year refining, processing, blending and storage facility near the port of Harwich in the UK. The refinery was commissioned in 1964 to process petroleum-based feedstocks into specialist hydrocarbon solvents. History The Carless Company was founded by Eugene Carless in 1859 to process naphtha and the by-products of coal gas production into solvents, petrol and diesel fuel. The company was known as Carless Capel when it was purchased by John Hare Leonard in 1873. It operated from sites in Hackney Wick and Bow in East London. The company was floated on the stock market in December 1948 as Carless, Capel and Leonard Limited. In the late 1950s and the early 1960s the British gas industry experimented with the use of oil-based rather than coal-based feedstocks to manufacture town gas. Carless realised that these changes would reduce the feedstock available for its processes and therefore also began to use petroleum-based feedstock available fr ...

Cracking (chemistry)
In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbonācarbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of large hydrocarbons into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking long-chain hydrocarbons into short ones. This process requires high temperatures. More loosely, outside the field of petroleum chemistry, the term "cracking" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naphtha
Naphtha (, recorded as less common or nonstandard in all dictionaries: ) is a flammable liquid hydrocarbon mixture. Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat. In some industries and regions, the name ''naphtha'' refers to crude oil or refined petroleum products such as kerosene or diesel fuel. Naphtha is also known as Shellite in Australia. Etymology The word ''naphtha'' comes from Latin through Ancient Greek (), derived from Middle Persian ''naft'' ("wet", "naphtha"), the latter meaning of which was an assimilation from the Akkadian šš³š (see Semitic relatives such as Arabic petroleum" Syriac ''naftÄ'', and Hebrew , meaning petroleum). Antiquity The book of II Maccabees (2nd cent. BC) tells how a "thick water" was put on a sacrifice at the time of Nehemiah and when the sun shone it caught fire. It adds that "those aro ...

Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the FischerāTropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmissionāduring the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australiaāalmost all gas for fu ...

Gasoline
Gasoline ( North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical st ...

Hackney Wick
Hackney Wick is a neighbourhood in East London, England. The area forms the south-eastern part of the district of Hackney, and also of the wider London Borough of Hackney. Adjacent areas of the London Borough of Tower Hamlets, namely Fish Island, are sometimes also described as being part of Hackney Wick. The area lies 4.2 miles (6.8 km) northeast of Charing Cross. Geography Hackney Wick is the south-eastern part of the historic district of Hackney, and also of the wider modern London Borough of Hackney. Adjacent parts of Old Ford (including Fish Island) in the London Borough of Tower Hamlets are also sometimes described as Hackney Wick, due to similar post-industrial land uses and their proximity to Hackney Wick railway station. The boundary runs along Wallis Road and the railway. The core area lies west of the Lee Navigation, here called Hackney Cut, however the parts of the Queen Elizabeth Olympic Park within Hackney have often also been described as Hackney W ...

North Sea Oil
North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea. In the petroleum industry, the term "North Sea" often includes areas such as the Norwegian Sea and the area known as "West of Shetland", "the Atlantic Frontier" or "the Atlantic Margin" that is not geographically part of the North Sea. Brent crude is still used today as a standard benchmark for pricing oil, although the contract now refers to a blend of oils from fields in the northern North Sea. From the 1960s to 2014 it was reported that 42 billion barrels of oil equivalent (BOE) had been extracted from the North Sea since when production began. As there is still an estimated 24 billion BOE potentially remaining in the reservoir (equivalent to about 35 years worth of production), the North Sea will remain as an important petroleum reservoir for years to come. However, this is the upper end of a range of estimates provided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacton, Norfolk
Bacton is a village and civil parish in Norfolk, England. It is on the Norfolk coast, some south-east of Cromer, north-west of Great Yarmouth and north of Norwich.

Parkeston, Essex
Parkeston is a North Sea port village in Essex, England, situated on the south bank of the River Stour about one mile (1.6 km) up-river from Harwich. In 2018 it had an estimated population of 932. History In the 1880s, reclaimed land that had been Ray Island was developed by the Great Eastern Railway Company (GER) as a railway depot for import/export trade with the European mainland. The new port was named Parkeston Quay, after Charles Henry Parkes (1816ā1895), Chairman of the GER. The existing railway line was re-routed to pass through the port, although the original railway embankment, through an overgrown area known locally as The Hangings, still exists. Most of the terraced housing in Parkeston was built for railway employees and some of the streets in the village have names that can be theoretically linked to the shipping and general activities of the railway, examples being Tyler Street (paddle steamer ''The Lady Tyler''), Hamilton Street (paddle steamer ''Claud ...

Batch Distillation
Batch distillation refers to the use of distillation in batches, meaning that a mixture is distilled to separate it into its component fractions before the distillation still is again charged with more mixture and the process is repeated. This is in contrast with continuous distillation where the feedstock is added and the distillate drawn off without interruption. Batch distillation has always been an important part of the production of seasonal, or low capacity and high-purity chemicals. It is a very frequent separation process in the pharmaceutical industry. Batch rectifier The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still. The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers. The pot is filled with liquid mixture and heated. Vapour flows upwards in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Stour, Suffolk
The River Stour (, pronounced rhyming with either "tour" or "sour") is a major river in East Anglia, England. It is long and forms most of the county boundary between Suffolk to the north, and Essex to the south. It rises in eastern Cambridgeshire, passes to the east of Haverhill, Suffolk, Haverhill, through Cavendish, Suffolk, Cavendish, Sudbury, Suffolk, Sudbury, Bures, England, Bures, Nayland, Stratford St Mary and Dedham, Essex, Dedham. It becomes tidal just before Manningtree in Essex and joins the North Sea at Harwich. The origins of its name are unclear, but several possibilities have been proposed by scholars. In 885, the river near Harwich was the site of the Battles of the River Stour. The entire non-tidal river above Manningtree is designated as the Dedham Vale National Landscape, Dedham Vale National Landscape, formerly known as an Area of Outstanding Natural Beauty. It has been painted by a number of prominent artists, including John Constable and Thomas Gains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dow Chemical Company
The Dow Chemical Company is an American multinational corporation headquartered in Midland, Michigan, United States. The company was among the three largest chemical producers in the world in 2021. It is the operating subsidiary of Dow Inc., a publicly traded holding company incorporated under Delaware law. With a presence in around 160 countries, it employs about 36,000 people worldwide.
