一种高效反相破乳剂在胜利油田海洋采油厂的应用

Application of an efficient reverse demulsifier in Offshore Oil Production Plant of Shengli Oilfield

合成了一种高效反相破乳剂MH-9,并将其与破乳剂MC-9368配合使用处理采油污水。瓶试实验结果表明,当MH-9与MC-9368投加量分别为30、40 mg/L时,脱水率高达95.3%。中试实验结果表明,MH-9与MC-9368配合使用能够将三相分离器的水相出口含油量降低50%左右,同时将分水速率从200 m3/h提升到300 m3/h。该复合配方优化了平台集输系统,解决了陆地联合站高负荷海洋平台来液的问题,并且综合加药量低,环保,经济性好。

A high-efficiency reverse demulsifier MH-9 was synthesized and used together with demulsifier MC-9368 to treat oil production wastewater.In the bottle test,when the dosages of reverse demulsifier and demulsifier were 30 mg/L and 40 mg/L,respectively,the dehydration rate was as high as 95.3%.In the pilot test of the Shengli Oilfield Marine Oil Production Plant,the oil content in the water outlet of the three-phase separator can be reduced by about 50%.Meanwhile,the water distribution rate increased from 200 m3/h to 300 m3/h.The platform gathering and tran-sporting system is optimized,and the problem of liquid inflow from high-load offshore platform of land joint station is solved.The advantages of this product are low dosage,environmental protection and good economy.
