The petroleum sulfonate market has broad development prospects, and oil extraction is its largest application field.

Petroleum sulfonate, with the molecular formula C23H38SO3M, is a high-quality surfactant, mainly used in petroleum mining and refining, chemical industry, rubber, plastics, dyes and other fields. According to different structures, petroleum sulfonates can be divided into two categories: aromatic petroleum sulfonates and aliphatic petroleum sulfonates.

The main production method of petroleum sulfonates refers to the process of using petroleum and its distillates as raw materials to generate petroleum sulfonates through sulfonation with sulfonating agents, alkali neutralization, separation and purification. Sulfur agents are important materials that affect the quality of petroleum sulfonate products. Currently, the sulfonating agents commonly used in industry mainly include sulfur trioxide, sulfuric acid, fuming sulfuric acid, chlorosulfonic acid, etc. Among them, sulfur trioxide is the mainstream vulcanizing agent required for the production of petroleum sulfonates, including gaseous and liquid forms.

Petroleum mining is the largest application field of petroleum sulfonate. In this field, it is mainly used as a surfactant in the tertiary oil recovery and oil displacement process of oil fields. It plays the role of reducing the oil-water interfacial tension, reducing rock formation adsorption, and improving the oil-water viscosity ratio, thereby achieving To enhance crude oil recovery. At present, petroleum sulfonate has become the most commonly used surfactant in domestic tertiary oil recovery and flooding processes, and its application areas have covered Daqing Oilfield, Shengli Oilfield, Xinjiang Oilfield, etc.

According to the “Petroleum Sulfonate Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center It shows that under the current background of my country’s continuous increase in oil exploration, the market demand for petroleum sulfonates continues to increase, and the industry shows good development prospects. According to data from the National Bureau of Statistics, domestic crude oil production will reach 205 million tons in 2022, a year-on-year increase of 2.9%. Against this background, the domestic petroleum sulfonate market size will be approximately 620 million yuan in 2022, and my country has become one of the major consumers of petroleum sulfonate in the world.

Due to technical limitations, the current global petroleum sulfonate production capacity is mainly concentrated in the hands of leading international companies such as the United States and Japan, including Japan’s MORESCO, the United States’ Chemtura, etc. my country’s dependence on petroleum sulfonate imports is still relatively high, and local companies will need to continue to optimize process technology in the future. The main domestic petroleum sulfonate manufacturers include PetroChina Karamay Petrochemical, Zanyu Technology Group, Shandong Daming Fine Chemicals, Qingdao Huicheng Environmental Protection Technology, Sinopec Nanjing Chemical Industry Research Institute, Tianjin Bohong Petrochemical, Daqing Huasen Technology, Shaanxi Bondano Environmental Protection Technology, Zhongqing Beide Petroleum Technology, Tianjin Gonghe Energy Concentration, etc.

Industrial analysts personnel said that petroleum sulfonates are an important type of surface activity required in petroleum extraction agent, with excellent interfacial activity, stability, adsorption and emulsification functions. In recent years, against the background of increasing domestic oil exploitation, the scale of petroleum sulfonates has continued to rise, and the industry has shown good development prospects. At present, most enterprises in my country have deployed in the field of petroleum sulfonate production. However, due to technical limitations, the domestic petroleum sulfonate production capacity is still relatively low and the product quality is relatively poor. In the future, local enterprises will need to continue to optimize process technology.
