Alkylation unit in a refinery, line width corresponds approximately to the mass flow (SAAU technology) The first alkylation units entered in service in 1940. In 2009 around 1,600,000 barrels per day of capacity were installed worldwide, [5] with an equal share of 800,000 barrels per day for SAAU and HFAU technologies. On the 1st January 2016 ...
Alkyl groups can also be removed in a process known as dealkylation. Alkylating agents are often classified according to their nucleophilic or electrophilic character. In oil refining contexts, alkylation refers to a particular alkylation of isobutane with olefins. For upgrading of petroleum, alkylation produces a premium blending stock for ...
The alkylation process takes place in the presence of an acid - in the Dangote refinery, this is sulphuric acid (H 2 SO 4). The plant is called a sulphuric acid alkylation unit (SAAU). [54] The main technology for SAAU is the STRATCO process licensed by DuPont. It is a very established technology for alkylation in refineries.
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
The Humber Refinery is a British oil refinery in South Killingholme, North Lincolnshire. It is situated south of the railway line next to the A160; Prax Group's Lindsey Oil Refinery is north of the railway line. It is situated approximately ten miles north west of Grimsby, and processes approximately 221,000 barrels (35,100 m 3) of crude oil ...
Transalkylation reactions of six to ten carbon methylated aromatics are often performed with the cofeed of hydrogen gas, over a zeolite based solid catalyst. Industrial processes operate the transalkylation reactor at elevated temperature and pressure to achieve desired process economics.
The Puget Sound Refinery is an oil refinery on March Point near Anacortes, Washington, United States. It is operated by HF Sinclair and is one of the largest employers in Skagit County . [ 3 ] The refinery has a capacity of 145,000 barrels a day, [ 4 ] making it the 52nd largest in the United States, in 2015, with facilities that include a ...
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
