中文摘要:
      为解决辽河老化油破乳脱水困难的问题, 在 KOH催化剂条件下, 以对叔丁基酚胺醛树脂为起始剂, 与环氧 乙烷(EO)、 环氧丙烷(PO)聚合反应合成一类新型对叔丁基酚胺醛树脂型破乳剂, 考察了 EO、 PO质量比及起始 剂与 PO质量比对所合成破乳剂的脱水性能的影响, 并分析不同破乳剂的羟值、 浊点、 HLB值及水数。研究结果 表明: 起始剂、 PO质量比为 1∶149, EO与 PO质量比为 1∶2时所合成的破乳剂 PTAE7的破乳效果最佳。浊点、 水 数及 HLB值均受起始剂与 PO质量比、 EO与 PO质量比的影响, PTAE7的浊点为 27.8℃, 水数为 7.34, HLB值为 6.62。在破乳温度 85℃、 破乳时间 150 min、 加剂量 100 mg/L的条件下 PTAE7破乳剂对辽河老化油的脱水率达 95.28%, 油水两相分离且界面清晰。图 4表 3参 18
英文摘要:
      In order to solve the problem of dehydration of aging oil in liaohe oilfield,p-tert-Butylphenol formaldehyde resin demulsifier was synthesized through ethylene oxide (EO) and propylene oxide (PO) polymerization reaction using p-tert-butylphenol formaldehyde resin as the initiator in the presence of KOH catalyst. The effect of the different proportion of initiator to PO, EO to PO on the performance of the dehydration, and the hydroxyl value, cloud point, HLB value and water number of demulsifiers was probed. The experimental results showed that when the ratio of initiator and PO was 1∶149 and the ratio of EO to PO was 1∶2 , the obtained demulsifier PTAE7 had the best demulsification effect. The cloud point, water number and HLB value of the demulsifier was affected by initiator/PO and EO/PO ratio. The cloud point of the demulsifier PTAE7 was 27.8℃, the water number was 7.34 and the HLB value was 6.62. After being treated by demulsifier PTAE7 with dosage of 100 mg/L for 150 min at the temperature of 85℃, the dehydration rate of the crude oil was up to 95.28% , and two-phase separation was visible with clear interface
