【Basic Knowledge Activity】Professional “Basic Knowledge” in the petrochemical industry: What are mechanical impurities in oils and fuels?

Mechanical impurities refer to all precipitated or suspended substances in petroleum or oils that are insoluble in the oil and specified solvents, such as sediment, dust, iron filings, fibers, and certain non-fusible salts. These impurities are introduced during extraction, refining, storage, or use. The content of mechanical impurities is a quality indicator for many oils. For light oils, mechanical impurities can block the oil passages, causing vulcanization or corrosion. When used as boiler fuel, they can clog the nozzles, reducing combustion efficiency and increasing fuel consumption. In the case of lubricating oils, they can damage the oil film, increase wear, clog oil filters, and promote the formation of sludge.

This initiative encourages various sections to create or individuals to post basic knowledge-related posts (the content can be gathered from the internet or created originally; participation can take place through multiple topics, with no restrictions on the approach used – it could be an explanation of a noun or an introduction to a series of principles). What are some suggestions and methods for getting in touch with cleaners? The regular administrator will reward the content that performs excellently. You will also be rewarded for regions where the activities are more intensive. (Regions should also carry out summarization and optimization based on the amount of such content available in their area.) ———————————————— The second phase of the campaign runs from February 20, 2016, to the end of June 2016; at least 50 award vouchers are available for you to claim (mugs, power banks, USB drives, and other prizes or campaign benefits).

Mechanical impurities are substances that exist in lubricating oil in a suspended or precipitated state, are insoluble in gasoline or benzene, and can be filtered out. Mechanical impurities in lubricating oil are substances such as dust, sediment, and iron shavings that remain unremoved during oil processing, or that enter the oil from the outside environment during storage, transportation, and use. These substances not only affect the performance of oils, such as causing blockages in oil pipelines, nozzles, filters, etc., but they also increase equipment corrosion, damage the oil film, and lead to increased wear and carbon deposition. Therefore, mechanical impurities are absolutely not allowed in light oils, while the requirement for heavy oils is less strict, generally limited to between 0.005% and 0.1%.
What are mechanical impurities in oils? Answer: Mechanical impurities in oils are foreign substances that enter petroleum products during storage, transportation, and use, such as sediment, ash, rust, metal particles, etc.
It refers to impurities present in oils that are insoluble in solvents; these impurities generally include sand, dust, iron filings, and mineral salts.
All impurities present in oils that are insoluble in specified solvents are called mechanical impurities.
Mechanical impurities refer to impurities present in oils that are insoluble in specified solvents (such as gasoline, benzene, etc.). These impurities generally refer to sand, dust, iron filings and mineral salts (such as iron oxide), as well as organic components that are insoluble in solvents, such as asphaltenes and carbides.
Therefore, impurities that are insoluble in the specified solvents
During the storage, transportation, and use of petroleum products, foreign substances from the outside environment can enter, such as sediment, ash, rust, metal powder, etc. Mechanical impurities can increase wear and clog oil passages during the use of oils. @sdshihua @Guan Gongyu @slll611 @chunhui1009 @OnlySingEcho @LinlinShangshang @zls1457 @BlackToothpaste @ZhangJun_nLlUg @MaYiyi
Mechanical impurities refer to all precipitated or suspended substances that are insoluble in solvents and are present in oils. It is mainly composed of sand, clay, iron filings, etc.
