摘要
从大庆油田长期受石油污染的土壤中筛选得到了生物破乳剂XH-1,考察了该生物破乳剂与化学破乳剂的复配及破乳效果。结果表明,生物破乳剂XH-1的破乳效果明显好于化学破乳剂的,其30min的除油率可达90.43%;在目前油田广泛使用的11种化学破乳剂中,PCI-1、CW-1和CW-2的破乳效果较好,30min的除油率分别为86.11%、83.51%和52.73%,可作为生物破乳剂XH-1的助剂;XH-1与助剂PCI-1复配时破乳效果最好,最佳复配剂量:XH-1为500mg/L、PCI-1为3mg/L,其30min的除油率可达96.78%。
The bio-demulsifier XH-1 was isolated from contaminated oily soil in Daqing Oilfield, and the combination and demulsification efficiency of this bio-demulsifier and chemical demulsifiers were investigated. The results show that the demulsification efficiency of bio-demulsifier XH-1 is significantly better than that of chemical demulsifiers, and the oil removal rate of XH-1 is 90.43% after 30 min. A- mong 11 commercial demulsifiers used at present, PCI-1, CW-1 and CW-2 are screened as additives for XH-1 for their excellent demulsification, and their oil removal rates are 86.11%, 83.51% and 52.73% respectively. The combination of bio-demulsifier XH-1 and additive PCI-1 has the best demulsification. The optimal dosages of XH-1 and PCI-1 are 500 mg/L and 3 mg/L respectively, and the oil removal rate is 96.78% after 30 min.
