Gasoline can be released into the Earth's environment as an uncombusted liquid fuel, as a flammable liquid, or as a vapor by way of leakages occurring during its production, handling, transport and delivery. [83] Gasoline contains known carcinogens, [84] [85] [86] and gasoline exhaust is a health risk. [75]
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.
Gas-to-liquids processes may also be used for the economic extraction of gas deposits in locations where it is not economical to build a pipeline. This process will be increasingly significant as crude oil resources are depleted. Royal Dutch Shell produces a diesel from natural gas in a factory in Bintulu, Malaysia.
expansion of the associated petroleum gas at the top of the reservoir; expansion of the associated gas initially dissolved in the crude oil; gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where well extraction is located. Recovery factor during the primary recovery stage is typically 5 ...
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.
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas.
Last December, gasoline profit margins peaked at 120% above the 2019 baseline, or 102% above the 2020 pre-COVID level. The profit margin on gas was about 6.7% in 2019, so at current levels, it’s ...
Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
