摘要
针对新疆高含水原油的特性,制备了非离子型双酚A酚胺醛树脂嵌段聚醚破乳剂(BPAE).酚胺醛树脂起始剂的合成工艺为双酚A、甲醛和二乙烯三胺按1∶4∶6的反应摩尔比例,在70℃、N2环境下充分反应1h,再在120~220℃下减压蒸馏得到酚胺醛树脂起始剂.将上述酚胺醛树脂作为起始剂依次与PO、EO进行开环聚合反应合成BPAE.通过热化学瓶试法,比较了BPAE、腰果酚胺醛树脂破乳剂(CPAE)、壬基酚胺醛树脂破乳剂(NPAE)、SP169在不同破乳剂加剂量、破乳温度、破乳时间对原油脱水的影响.通过这几种聚醚破乳剂的破乳脱水实验表明,胺基改性酚醛树脂嵌段聚醚的破乳效果很好,其中BPAE破乳效果最优.在破乳剂浓度为25mg/L、破乳温度40℃、破乳时间为120min条件下,原油脱水率可达85.4%.
Aiming at the characteristic of Xinjiang crude oil with high water content,prepared a non-ionic bisphenol A phenol amine aldehyde resin block polyether demulsifier( BPAE). Phenol amine aldehyde resin initiator was synthesized when the molar ratio of bisphenol A to formaldehyde to diethylenetriamine was 1 ∶ 4 ∶ 6,the reaction temperature was 70 ℃,adequate response 1 h under N2 atmosphere,and vacuum distillation at 120 ~ 220 ℃. Using phenol amine aldehyde resin as initiator,synthetic BPAE through polymerization reaction with PO and EO. Using chemical bottle test,compared BPAE,cardanol phenol-amine resin demulsifier( CPAE),nonylphenol phenol-amine resin demulsifier( NPAE),SP169 effect on crude oil dehydration at different demulsifier dosage,temperature and time. Through this several kinds of polyether demulsifiers demulsification dehydration experiment showed that the amino modified phenolic resin block polyether demulsification effect is very good,including BPAE demulsification effect optimal. The demulsification efficiency can be up to 85. 4% at the concentration of 25 mg / L,the temperature of 40 ℃and the time of 120 min.
