Compound Crude Oil Demulsifier (AD-501)


After the emulsion formed from crude oil containing water, its viscosity, density and freezing point increases, this makes the liquidity of crude oil worse, oil well production load rising and the energy consumption increasing, at the same time, the storage and transportation energy consumption also getting higher.

A summary treatment of crude oil follows. For full treatment, see petroleum, petroleum production, and petroleum refining.

Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. Regardless of variations, however, almost all crude oil ranges from 82 to 87 percent carbon by weight and 12 to 15 percent hydrogen by weight.

Crude oils are customarily characterized by the type of hydrocarbon compound oil that is most prevalent in them: paraffins, naphthenes, and aromatics. Paraffins are the most common hydrocarbons in crude oil; certain liquid paraffins are the major constituents of gasoline (petrol) and are therefore highly valued. Naphthenes are an important part of all liquid refinery products, but they also form some of the heavy asphaltlike residues of refinery processes. Aromatics generally constitute only a small percentage of most crudes. The most common aromatic in crude oil is benzene, a popular building block in the petrochemical industry. And Grill
