| titleOfInvention | A kind of preparation method of high dehydration rate oil field demulsifier |
| abstract | The invention relates to a preparation method of a high dehydration rate oil field demulsifier, and belongs to the technical field of crude oil dehydration. In the present invention, tofu is used as a raw material, after being chopped, it is flattened, placed in a high temperature and high humidity environment to form mold, the moldy tofu and castor oil are mixed and fermented to obtain fermented tofu, and then the fermented tofu pulp is reacted with acid chloride to obtain the main component of the demulsifier. Then, the main component of the demulsifier is mixed with sodium silicate, and the orthosilicic acid is precipitated by the reaction of hydrochloric acid and sodium silicate, which is adsorbed on the surface of the main component of the demulsifier, and then the orthosilicic acid is hydrolyzed under high temperature conditions to form nano-silica. Thereby, the composite structure of nano-silica and the main component of demulsification is obtained, and finally a high dehydration rate oil field demulsifier is obtained. good use effect. |
