(PS-NB Petroleum Sulfonate CAS 61789-85-3)

Overview Of Petroleum SulfonatePetroleum Sulfonat is an anionic surfactant prepared from petroleum and its fractions through sulfonation and neutralization reactions. The composition of petroleum sulfonates is relatively complex because the raw materials are mostly mixtures, and their molecular weight, structure, and properties will affect their performance in different applications.

Petroleum sulfonates can be simply divided into two categories: aromatic and aliphatic. Among them, aromatic petroleum sulfonates are mainly used as surfactants in tertiary oil recovery and have a good effect on reducing the interfacial tension between crude oil and formation water. Petroleum sulfonates can be used in combination with alkaline agents to reduce interfacial tension over a wide range of surfactant and alkaline mass fractions, thereby improving oil washing efficiency.

Applications Of Petroleum SulfonateTertiary oil recovery: Petroleum sulfonates are used as the main surfactant in tertiary oil recovery. In the process of oil extraction, due to the high viscosity and water content of the crude oil in the reservoir, traditional oil extraction methods often find it difficult to effectively extract crude oil. Petroleum sulfonates can be used in combination with alkaline agents to form low interfacial tension oil-in-water emulsions, thereby reducing the interfacial tension between crude oil and formation water and improving the recovery rate of crude oil.

Applications of Petroleum Sulfonate

Crude oil demulsification: in the process of crude oil processing, the crude oil contains a large amount of water and emulsifier, which will form a stable oil-water lotion. Petroleum sulfonate can be used as demulsifier to destroy the stability of lotion and separate oil from water, thus facilitating subsequent crude oil processing.

Ore flotation: Petroleum sulfonates can be used as collectors in the flotation process of ores. Due to its good wettability and selectivity, it can effectively combine ore particles with bubbles, thereby achieving flotation separation of ore.

Lubricant additive: Petroleum sulfonates can be used as additives in lubricants to improve their extreme pressure, wear resistance, and oxidation resistance. Under harsh working conditions such as high speed, high temperature, and heavy load, petroleum sulfonates in lubricating oil can effectively reduce friction and wear, and extend the service life of mechanical equipment.

Other fields: Petroleum sulfonates can also be used to prepare other chemicals, such as calcium petroleum sulfonate, magnesium, barium, and sodium salts. In addition, it is also widely used in industries such as pesticides, rubber, textiles, and papermaking.

FAQQ1

How are petroleum sulfonates synthesized?

Answer:The synthesis of petroleum sulfonates is usually achieved by a sulfonation reaction between petroleum fractions and sulfuric acid or oleic acid, followed by a neutralization reaction. Hydrocarbon compounds in petroleum fractions undergo a sulfonation reaction with sulfuric acid to generate corresponding sulfonic acid. This is then neutralized with bases such as sodium hydroxide and potassium hydroxide to obtain petroleum sulfonates.

Q2

What is the role of petroleum sulfonates in tertiary oil recovery?

Answer:In tertiary oil recovery, the main function of petroleum sulfonates is to reduce the interfacial tension between crude oil and formation water, forming water in oil emulsion with low interfacial tension, thereby improving the recovery rate of crude oil. In addition, it can also be used in combination with alkaline agents to increase the stability of emulsions and improve oil-washing efficiency.

Q3

What is the application principle of petroleum sulfonates in crude oil demulsification?

Answer:The application principle of petroleum sulfonates in crude oil demulsification is mainly based on their demulsification effect. When petroleum sulfonate is added to the lotion of crude oil, it can destroy the emulsion film and separate oil from water. In addition, petroleum sulfonates can also reduce the interfacial tension between oil and water, promote the aggregation and settling of oil droplets, and thus achieve the demulsification of crude oil.

Q4

What is the environmental friendliness of petroleum sulfonates?

Answer:The environmental friendliness of petroleum sulfonates is related to their molecular structure, production process, and application methods. Improper handling during production and use may cause certain environmental pollution. However, its environmental impact can be effectively reduced by adopting environmentally friendly production processes and reasonable application methods. In addition, some studies are also exploring methods for converting petroleum sulfonates into environmentally friendly surfactants.

Q5

What is the market prospect of petroleum sulfonates?

Answer:With the increasing reduction of petroleum resources and the improvement of environmental protection requirements, the market prospects of petroleum sulfonates have been affected to a certain extent. However, due to its excellent performance and wide applicability, petroleum sulfonates still have broad application prospects in petroleum extraction, processing, transportation, chemical, pharmaceutical, environmental protection and other fields. At the same time, with the continuous progress of science and technology and the increasing environmental requirements, the production process and application methods of petroleum sulfonates will also be continuously improved and optimized, bringing new opportunities for their market prospects.
