Most additives are non-ionic surfactants

In the production of petroleum products, in order to improve and improve the performance of petroleum products, we must also add various additives, which can be divided into antioxidant, antiwear agent, detergent, dispersant, viscosity regulator, pour point depressant, rust inhibitor, fuel energy-saving agent, etc. according to their functions, most of them belong to non-ionic surfactants.

For example, aliphatic amine polyoxyethylene ether can be used as pour point depressant for fuel oil and lubricating oil. Surfactants used in antirust agents include sorbitol monooleate and trioleic acid ester, polyethylene glycol dioleic acid ester, polyoxyethylene nonionic surfactant, etc. Microemulsion or solubilization of water in natural feed oil can play a significant energy-saving effect. Therefore, we can use disc, tween, etc.

Nonionic surfactants have excellent washing properties and strong decontamination ability even at low concentrations; Less foam; Easy to make liquid detergent; It does not dissociate when dissolved in water, and is not sensitive to hard water and electrolytes; The critical micelle concentration is very low and has good solubilization ability; Emulsification, dispersion, wetting and anti redeposition properties are also very good; High stability, acid and alkali resistance, easy biodegradation. Therefore, it is widely used to prepare various detergents, and its variety and dosage are increasing year by year.

Oilfield chemicals play an important role in oil exploration and development, which is related to the smooth progress of oil exploration and development. However, the main problems in the field of oilfield chemicals in China are:

(1) There are few varieties and low degree of serialization, especially few original products with special properties.

(2) Most oil field chemical production plants have backward equipment and technology, and the production scale is relatively small.

(3) Research and development forces are scattered, and a virtuous cycle of research, development and application has not been formed. Many products are limited to low-level repeated research.

(4) Technical standards are not unified. Most products are set by enterprises themselves, and the level is low.
