采用自己研究的药剂对辽河油田特稠油污水进行破乳和净水试验 ,找出了主要影响因素 ,确定了处理工艺的操作条件。结果表明 ,使用破乳剂DI ,可使油的回收率大于99 % ;絮凝剂A中添加了收缩絮体的化学药剂B之后作为净水剂 ,使积杂量小于5 %(体积比)。同时 ,处理后的水完全达到辽河油田要求的指标 ,即油含量小于5mg/L,积杂量小于15mg/L
Using the reagents of our own research, the demulsification and water purification tests were conducted on the special heavy oil wastewater in Liaohe Oilfield. The main influencing factors were identified and the operating conditions of the treatment process were determined. The results showed that the recovery rate of oil was more than 99% by using demulsifier DI. After the chemical flocculant A with shrinkable flocculant B was used as the water purifying agent, the amount of accumulated impurities was less than 5% by volume. At the same time, the treated water fully meets the requirements of the Liaohe Oilfield with oil content of less than 5 mg / L and accumulated less than 15 mg / L
