High carbon number black condensate anti-foam drainage agent, preparation method and application thereof

Abstract

The present application relates to a kind of anti-high carbon number black condensate foam drainage agent, preparation method and its application, the foam drainage agent is made of the following weight percentage components: tetradecyl amide propyl dimethyl tertiary amine 17%~25%, octadecyl amide propyl dimethyl tertiary amine 3%~5%, 3-chloro-2-hydroxy sodium propyl sulfonate 15%~20%, N,N-dimethylformamide 2%~5%, isophorone diisocyanate 3%~5%, non-ionic surfactant 3%~6%, perfluorooctyl polyether surfactant 0.5%~3%, the balance is water.The present application anti-high carbon number black condensate foam drainage agent is made of the twin surfactant of low surface tension, good oil resistance performance betaine surfactant, and non-ionic surfactant and perfluorooctyl polyether surfactant are compounded to obtain, in the environment of high carbon number black condensate oil, still have good foam drainage effect, with higher liquid carrying rate.
