In recent years, the water content of oilfield production fluid is high and there is a large amount of oily sewage. In order to improve the capability of sewage treatment, usually using demulsifier for oily sewage processing. This article uses simulated water sample to test the treatment effect of the optimized reverse demulsifier at different oscillation time. As the increase of action time and oscillation, the average size of droplets increases and the amount of the droplets under 1 μm decreases.

Open Journal of Yangtze Oil and Gas 2019年第3期4卷 212-224页

Stable water-in-oil emulsions are produced in oil exploitation and cause many environmental and operational issues.In this paper,a co-polymer demulsifier is reported in detail;an emulsion polymerization method is used to prepare nano-P(MMA-AA-EA)with MMA,AA and EA as the monomers,DVB as the cross-linker and APS as the initiator.The resulting products are characterized by FT-IR.Furthermore,the surface tension and particles size analysis is investigated.The results show that the surface tension reduction is 10.66 mN/m at 20?C when the concentration of co-polymer is 1000 ppm and the average size is 76.99 nm.Moreover,the HLB of polymer is discussed specifically by changing the amount of AA.With the increase of AA,the HLB value of the polymer is increased accordingly.Besides,the demulsification performance of the co-polymer is also evaluated at different synthesis and demulsification conditions.It is showed that the maximum demulsification efficiency is 96%at 70?C for 60 min.The optimum concentration of demulsifier is 400 ppm when the amounts of AA and DVB are 1.4 g and 0.1 g,respectively.At last,the process of demulsification is showed under a microscope;the coalescence process of water droplets is indicated under the action of the demulsifier.

The crude oil in Longdong area is produced in the form of emulsion containing associated oil and water which needs to be separated before dispatch to end user. Chemical demulsification is most widely used technology to break the emulsions. A series of experiments on low temperature demulsifies were implemented for studying demulsification performance by Bottle Test method and Turbiscan stability analyzer to study the effect of water content, temperature, and demulsifier concentrations. Rheological method is used to determine the curve of viscosity-temperature. Different commercial demulsifiers were used. Efficient low temperature AR102, AR901, PR929, and PRC06 demulsifiers were selected. PRC06 was chosen to be the best at 40℃, and when the optimal concentration was 200 mg/L, dehydration rate was 99.51%, and study was performed to observe dehydration condition of different demulsifiers, the dehydration performance was convincingly high.
