Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
With the use of non-edible vegetable oils produced by trees such as Millettia Pinnata (formerly Pongamia Pinnata) or the Moringa oleifera tree, both which grow on borderline or non-arable land, the food versus fuel debate becomes less of an either/or question. Apart from their facility of growing in non-arable and/or marginal land, these trees ...
Crude oil map Main features of some qualities of crude oil Density and sulfur content of crude oils. In the international petroleum industry, crude oil products are traded on various oil bourses based on established chemical profiles, delivery locations, and financial terms. The chemical profiles, or crude oil assays, specify important ...
Crude oil, or petroleum, and its refined components, collectively termed petrochemicals, are crucial resources in the modern economy. Crude oil originates from ancient fossilized organic materials , such as zooplankton and algae , which geochemical processes convert into oil. [ 8 ]
Amateur use of mineral oil follows industrial use, since it typically is the insulating and cooling fluid in large electrical transformers and similar equipment, such as small switches used for high-voltages. Mineral oil is used as a brake fluid in some cars, such as Citroën models with hydrodynamic suspension, and bicycle disc brakes.
Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products. Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical ...
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.
Hemp oil, a high quality food oil [91] also used to make paints, varnishes, resins and soft soaps. [92] Kapok seed oil, from the seeds of Ceiba pentandra, used as an edible oil, and in soap production. [93] Kenaf seed oil, from the seeds of Hibiscus cannabinus. An edible oil similar to cottonseed oil, with a long history of use. [94] [95]
