The types of crude oil pour point depressants are becoming increasingly abundant, and compounding, environmental protection, and universal application have become important development directions.

Crude oil pour point depressant, also known as pour point depressant, is an oil additive. It is mainly used to change the crystallization form of paraffin in oil, reduce the pour point and viscosity of crude oil, and improve the performance of crude oil in oil production, gathering, transportation, storage and other operations. resource utilization and economic benefits. There are many types of crude oil pour point depressants with different action mechanisms. Currently, the more recognized action mechanisms include eutectic theory, adsorption theory, dissolution principle, anti-coagulation mechanism, eutectic-adsorption mechanism, crystal nucleation theory, etc.

my country’s crude oil comes in various forms and has greatly different compositions. In recent years, the crude oil produced by my country’s oil fields is mainly wax-based crude oil, which has the characteristics of high wax content, high pouring point and high viscosity. At low temperatures, wax-based crude oil has poor fluidity, and long-term suspension of transportation can easily cause condensation pipe accidents, thereby increasing transportation, processing, storage and handling costs. Pour point depressants help reduce the freezing point of crude oil, and their economy, environmental protection, and convenience are better than dilution transportation methods, emulsification transportation methods, etc. Therefore, adding pour point depressants has become one of the main measures to solve the poor fluidity of low-temperature wax-based crude oil. .

In the international market, the crude oil pour point depressant market is highly concentrated. The main suppliers are Dow, BASF, Evonik, Klein, Arkema, Huntsman, PetroChina, Dongying Runke, Xinchang Zhuorun, and Gulet Technology. wait. my country’s crude oil pour point depressant research and development and production lag behind European and American countries for more than ten years. The types and quantities of pour point depressants are less than those in foreign markets. Some products rely on imports. However, imported crude oil pour point depressants are expensive and most are not suitable for the high wax characteristics of local crude oil.

According to the “2022-2027 China Crude Oil Pour Point Depressant Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Crude oil pour point depressants are mainly used in the fields of crude oil transportation, crude oil processing, and crude oil extraction, of which crude oil transportation applications account for more than 65%. In the past two years, due to the impact of the COVID-19 epidemic, the production of crude oil pour point depressants has not grown significantly. The global production is about 194,000 tons/year. Among them, compound type pour point depressants have outstanding advantages, and their growth rate is higher than that of surfactant type pour point depressants. and copolymer type pour point depressants.

Types of crude oil pour point depressants are mainly divided into surfactant-type pour point depressants, copolymer-type pour point depressants, compound type pour point depressants, etc. Among them, copolymer-type pour point depressants are the mainstream products in the market. Surfactant-type pour point depressants include petroleum sulfates, polyoxyethylene alkylamine type pour point depressants, etc.; copolymer-type pour point depressants are divided into three types: polyurethane, polyolefin, and long-chain alkyl naphthalene, among which polyurethane The pour point depressant is widely used; the compound pour point depressant combines the action mechanism of two or more pour point depressants, and has the advantages of good pour point reducing effect and wide adaptability.

Industry analysts said that the types of crude oil pour point depressants have become increasingly abundant. In recent years, with the development of the market and the in-depth research on the pour point depressant mechanism, , new and compound crude oil pour point depressants have begun to flood into the market. At the same time, under the background of increasingly stringent environmental protection requirements, economical, environmentally friendly, efficient, and universally applicable crude oil pour point depressants have also become the key development directions of crude oil pour point depressants. Crude oil pour point depressants help to reduce costs and increase efficiency in the crude oil industry. my country is a major crude oil producer, and the crude oil pour point depressants market has broad development space.
