The commonly used nonionic demulsifiers in oil fields are mainly as follows: 1. SP type demulsifier The main component of SP-type demulsifier is polyoxyethylene polyoxypropylene octadecyl alcohol ether, with the theoretical structural formula R(PO)x(EO)y(PO)zH, where: EO – polyoxyethylene; PO –…
Abstract Demulsifier is a kind of chemical used to destroy the stability of emulsion, which is widely used in petroleum industry, wastewater treatment, food industry, pharmaceutical and other fields. In this paper, the classification, mechanism of action, application fields, influencing…
Demulsifiers are used in oil fields to separate the crude oil from the water and salt that are produced along with it. Crude oil is often mixed with water and salt in the form of an emulsion, which is a…
