Background
The sulfonate surfactants are the most productive and widely applicable anionic surfactants, and are also the ones developed earlier and of more varieties. The petroleum sulfonate surfactant is a common surfactant in tertiary oil recovery, and is widely used in various oil fields in China due to low price and good oil displacement effect.
The petroleum sulfonate is prepared by using crude oil distillate oil as a raw material, sulfur trioxide as a sulfonating agent, dichloroethane or dichloromethane as a solvent and performing sulfonation reaction, neutralization reaction and solvent purification. Because the raw oil contains polycyclic aromatic hydrocarbons such as colloid, asphaltene and alkyl naphthalene, acid residues which are insoluble in dichloroethane are easily generated during the sulfonation reaction, and the acid residues can be adhered to the inner wall of the heat exchanger, thereby causing the heat exchange difficulty and further causing the temperature rise of the sulfonation reaction. If the sulfonation reaction temperature is higher than 25 ℃, side reactions such as carbonization, coking, sulfone formation and the like are increased, and the quality of the product is reduced.
The stainless steel heat exchanger is adopted in the traditional production process, although the inner wall of the heat exchange tube is polished necessarily, the inner wall of the heat exchange tube is inevitably corroded along with the increase of the service life, and therefore the adhesion rate of acid sludge is greatly improved. Sulfonic acid belongs to strong acid organic acid, and if the sulfonic acid is washed by water, the inner wall of the heat exchange tube is seriously corroded, and perforation is easily caused.
