The effective application of efficient reverse demulsifier stellate polyquaternium.

Using organic amines such as secondary amines and tertiary amines polymerize propylene oxide ring-opening to get linear polyquaternium, using PAMAM as a crosslinking agent then obtained
stellate polyquaternium reverse demulsifier. Its advantages are mild reaction conditions, readily available raw materials, unique structure of products, is cationic organic macromolecule, and has a
charge neutralization, replacement, adsorption, bridging performance, add 5 ~ 30ppm can effectively remove oil,suspended solids and other pollutants from the oily sewage , effectively reduce the oil content ,color, COD and other indicators in treatment sewage.The stellate polyquaternium efficient reverse demulsifier respectively, in Huabei Oilfield, Liaohe Oilfield, Daqing Oilfield carried out using the evaluation and achieved good effect. Weihai CY Dendrimer Technology Co.,Ltd fowards from "One method for preparing efficient stellate polyquaternium reverse demulsifier" Patent No.: 200810115284.3 Applicant: China National Offshore Oil Corporation co-applicants: Tianjin Chemical Research and Design Institute invention person: Sufen Wang, Guangyuan Yao,Bei Lin, Jiajun Li, Houkai Teng,Shuzhong Zheng.
