Abstract:The block polyether demulsifier prepared by ring-opening polymerization of ethylene oxide and propylene oxide under high temperature and high pressure is the most widely used demulsifier for water in crude oil emulsion. It has the high synthesis risk and cost. Therefore, the development of non-block polyether demulsifier has attracted more and more attention. In this article, a new type of demulsifier was sythesized by radical polymerization of acrylate and cationic monomer. It was found that the copolymer PMA… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
