含聚污水除油剂的研制和应用
|
摘要
随着聚合物驱的深入,油田含聚污水的成分渐趋复杂,处理量及处理难度也随之增大,因此针对含聚污水的高效低价除油剂的开发有着非常重要的意义。本文概括介绍了国内含聚污水处理工艺、使用药剂现状和研究进展,在此基础上提出了以二乙烯三胺同双氰胺预聚后引入己二胺和环氧氯丙烷合成除油剂的反应路线,讨论了原料配比、反应温度、恒温时间等条件对产品的最终形态及性能的影响,得到的最优合成条件为:(1)二乙烯三胺和双氰胺以1.0:1.0摩尔比、150℃下恒温5.0h进行预聚,生成50.0%预聚物水溶液;(2)加入50.0%已二胺和预聚物水溶液,两者摩尔比为0.8:0.2,在50℃下向混合物中以摩尔比1.0:0.8滴加环氧氯丙烷并在70℃恒温2.0h。评价表明,所合成的除油剂加药浓度8.0mg/L、沉降时间30min时除油率可达94.0%以上。该除油剂已在胜利油田埕东联合站实施现场应用,加药量350kg/d时即可使回注水含油达标。
With the developing of polymer flooding, sewage containing polymer is becoming more and more complex to deal with for its cpmplex constitue. Thereore, the oil remover with high efficency and low cost for sewage containing polymer is required. The domestic polymer-bearing wastewater treatment process, the status and use of pharmaceutical research progress were firstly summarized in this paper, then a new route to prepare oil remover, in which diethylene triamine, dicyandiamide, hexane diamine and epichlorohydrin were selected materials, was proposed. Such influence as the proportion of material, reaction temperature, constant temperature time on the apperance and performance was discussed, and the optimum reaction conditions were obtained as follows: to prepare prepolymer with mass percent of 50.0%, mole of ratio of diethylene triamine and dicyandiamide is 1.0:1.0, reaction temperature is 150℃, reaction time is 5.0 hours; to prepare final product, mole of ratio of hexamethylen diamine (50.0%) and prepolymer is 0.8:0.2,epichlorohydrin dropping temperature is 50℃, keep temperature at 70℃for 2.0 hours, the mole of ratio of the mixture and epichlorohydrin is 1.0:0.8. The results of evluation showed that, a oil removing efficency of 94.0% can be attained with obtained oil remover of a mass concentration of 8.0mg/L and settling for 30mins. This oil remover has been applied in Chengdong union station of Shengli oil field. With a dose of 350kg/d, oil content in the sewdge can be reduced to reach the standard of recirculated water.
