【摘要】 以丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)和苯乙烯(ST)为原料,聚甘油丙烯酸酯为扩链剂,过氧化二苯甲酰(BPO)为引发剂,甲苯为溶剂,进行自由基聚合,合成了一种非聚醚类的原油破乳剂。考察聚合诸因素对产物破乳性能的影响。实验表明,当单体质量比(MMA∶BA∶ST)为1∶3∶1,单体总量9g,聚甘油丙烯酸酯1.3g,引发剂用量为0.2g,溶剂用量30g,聚合温度80℃,反应时间6h时,原油破乳效果最好,在破乳剂加量300mg/L时,原油破乳脱水率达72.43%。更多还原

【Abstract】 A kind of non-polyether demulsifiers was synthesized by radical polymerization of BuAc,MMAc and styrene as material,polyglycerol acrylate as chain extender,BPO as initiator,toluene as solvent.Aimed at the dehydration rate of crude oil,the reaction conditions including monomer proportion,polymerization temperature,polymerization time,the category and dosage of initiator,solvent dosage were studied.The conditions of demulsification were studied too.The optimum condition and technology were shown as follows:the total of monomer was 20 g,the proportion of monomer MMAc∶BuAc∶Styrene=1∶3∶1,polyglycerol acrylate dosage 1.3 g,dosage of initiator 0.2 g,solvent dosage 30 g,polymerization temperature 80 ℃,polymerization time 6 h.Under the optimum condition and the dosage of demulsifier 300 mg/L,the dehydration rate of crude oil was up to 72.43%.更多还原
