Research and Application of Combinational Demulsifier

Article Preview

Abstract:

The dehydrationrate of Daqing crude oil was not stable and the amount of chemical demulsifier used too much, which caused serious environmental pollution and enlarged the difficulty of dealing with crude oil. Therefore, PRJ-1 bio-demulsifier was selected to combine with chemical demulsifiers SP-169 and GT-D01, respectively, to resolve the crude oil emulsion of Daqing. The results showed that PRJ-1 can combine with SP-169 efficiently. The demulsification efficiency was high and dehydrated water was clear. However, the demulsification efficiency increased a little with GD-D01. The study shows that efficient synergetic effect between PRJ-1 and SP-169 was confirmed. The suitable proportionality of combinational demulsifier is 1:1 and the demulsifying effect can meet requirement of oilfield demulsifiers currently.
