摘要
本文介绍了DPA型高效原油破乳剂的研制情况。该破乳剂在江汉油田4年多的生产应用中取得好效果,脱水、脱盐效率高,脱水速度快,低温性能好,脱水温度为43~45℃(环境温度),平均加药量为6.1ppm,而且只需一次加药,即可达到:外输原油含水0.07%,含盐量可从9~11×10~4mg/L降至100mg/L左右。DPA破乳剂具有原料易得,合成工艺简单,成本低,既可溶于水又可溶于油的优点。已在南阳、中原、华北等油田和洛阳、石家庄、乌鲁木齐、广州等地炼油厂进行了生产应用,收到了明显经济效益。以江汉油田王一站现场应用DPA与SAP对比为例,DPA的最大优点是在保证原油外输质量的情况下,每年可节省破乳剂19t,节省标准煤4480t,节电24365kW·h。本项目已获1987年国家发明三等奖。
This type of demulsifying agent has been used in Jiang Han Oilfield for more than 4 years and got fairly good results. It has a high efficiency and good property in dehydration and desalting. The dehydration temperature is 43~45##. Average amount of agent added is 6.1ppm.
