Problems solved by technology

Emulsifier is a surface-active substance, which has both hydrophilic and lipophilic groups in the molecule. It gathers on the oil / water interface, which can reduce the interfacial tension and reduce the energy required to form an emulsion, thereby increasing the energy of the emulsion. Among them, Existing crude oil emulsifiers have poor thermal stability and emulsifying performance, are not easy to form, have poor oil displacement effects, cannot meet the requirements of heavy oil viscosity reduction, and are not conducive to production and transportation

Abstract

The invention relates to the technical field of industrial emulsifiers, in particular to a composite crude oil emulsifier. The composite crude oil emulsifier is prepared from the following componentsin parts by mass: 8 to 12 parts of sodium dodecyl sulfonate, 17 to 23 parts of sodium stearate, 7 to 13 parts of n-hexyl nitrate, 12 to 18 parts of polyethylene glycol, 6 to 10 parts of sodium hydroxide and 4 to 8 parts of methanol. The crude oil emulsifier prepared by the formula has higher thermal stability and emulsifying performance, and is easy for forming emulsions, so that the composite crude oil emulsifier has a certain oil displacement effect, can meet the requirements of heavy oil viscosity reduction, and is conducive to extraction and transportation.

Description

technical field [0001] The invention relates to the technical field of industrial emulsifiers, in particular to a composite crude oil emulsifier. Background technique [0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface-active substance, which has both hydrophilic and lipophilic groups in the molecule. It gathers on the oil / water interface, which can reduce the interfacial tension and reduce the energy required to form an emulsion, thereby increasing the energy of the emulsion. Among them, The existing crude oil emulsifiers have poor thermal stability and emulsifying performance, are not easy to form, have poor oil displacement effects, cannot meet the requirements of viscosity reduction of heavy oil, and are not conducive to production and transportation. Contents of the invention [0003] In order to overcome the e...
