Background technology
One of oil, the main object of geological prospecting, it is a kind of sticky, dark brown liquid, is referred to as " industrial blood
Liquid ".There is petroleum storage upper crustal some areas.Main component is the mixture of various alkane, cycloalkane, aromatic hydrocarbon.Oil
Mainly it is made up of different hydrocarbon mixing, the chemical element of composition oil is mainly carbon (83%~87%), hydrogen
(11%~14%), remaining is sulphur (0.06%~0.8%), nitrogen (0.02%~1.7%), oxygen (0.08%~1.82%) and micro-
Measure metallic element (Ni-V-Fe, antimony etc.).The chief component that the hydro carbons formed constitutes oil is closed by carbon and hydrogenation, accounted for
95%~99%, various hydro carbons are divided into by its structure：Alkane, cycloalkane, aromatic hydrocarbon.General natural oil not olefin-containing and it is secondary
Process the alkene and alkynes often not waited containing quantity in product.Sulfur-bearing, oxygen, nitrogen compound are harmful to oil product, in oil
The removing oil that should be tried one's best in processing is mainly used as fuel oil and gasoline, is also many chemical industries, such as solution, change
The raw material of fertilizer, insecticide and plastics etc..Lubricating oil is used in all kinds automobile, in plant equipment to reduce friction, protect machine
The liquid or semisolid lubricants of tool and workpiece, mainly play lubrication, supplement heat rejecter, antirust, cleaning, sealing and buffering etc. and make
With, as long as between object applied to two relative motions, and friction and mill that two articles are produced by contact can be reduced
The function of damage, as lubricating oil.Lubricating oil is a kind of technology-intensive product, is the mixture of complicated hydrocarbon, and
Its real performance is the comprehensive effect of complicated physically or chemically change procedure again.Lubricating oil is general by base oil and addition
Agent two parts are constituted.Base oil is the main component of lubricating oil, decides the fundamental property of lubricating oil, additive can then make up and
Improve the deficiency of base oil aspect of performance, assign some new performances, be the important component of lubricating oil.Lube base oil
Mainly divide mineral base oil, synthetic base oil and biological basis oily three major types.Mineral base oil is widely used, and consumption is very big
(about more than 95%), but some application scenarios must then use the product of synthetic base oil and bio oil formulation of base oil, thus
Developed rapidly both base oils.
Oil drum, i.e., for the device for depositing oil or lubricating oil, at present, some oil field plant equipment are huger,
When needing oil lubrication in use, it usually needs the transport back and forth of oil is lubricated with keg, when consuming
Between and labour, and in the handling process of oil drum, artificial operated also has certain danger；Also, use crane
