针对文 11联合站原油脱水与注入水处理简易流程 ,在室内筛选出反相破乳剂RD 1以取代原用破乳剂DR95 1,又筛选了阻垢剂HEDP、净水剂聚合氯化铁 +聚合氯化铝、杀菌剂HCB 2 ,在文 11联矿场简易流程试验中使用这一组化学剂 ,使破乳剂加量由 2 8.6mg/L降到 8.7mg/L ,脱水电流由 15A降到 5A ,电脱水温度由 70℃降到 6 0℃ ,脱出污水含油由1371mg/L降到 45— 5 0mg/L ,消除了系统结垢 ,净化油含水和注入水水质均达到要求指标 In view of the simple process of crude oil dehydration and injection water treatment at the joint station of Wen 11, the reverse phase demulsifier RD 1 was screened indoors to replace the original demulsifier DR95 1, and the scale inhibitor HEDP and water purifying agent of polymeric ferric chloride + polymerization Aluminum chloride and bactericidal agent HCB 2. The chemical agent was used in the simple flow test of 11 coal mines to reduce the dosage of demulsifier from 28.6mg / L to 8.7mg / L and the dehydration current dropped from 15A 5A, the temperature of electrothermal dehydration dropped from 70 ℃ to 60 ℃, the oil content in effluent was reduced from 1371mg / L to 45-550mg / L, the system fouling was eliminated, and the purifying oil water and injection water quality met the requirements
