Effect of Anion Non-Ion Complex System on Emulsification Property of Heavy Oil
The effects of a single emulsifier octylphenol ethoxylate 10(OP-10)and its compounding system on emulsion stability,rheology and the effect of organic bases on the interfacial tension were investigated.The results show that the optimal binary composition is as follows:The mass fraction of OP-10 is 1%and the mass fraction of sodium oleate(YSN)is 0.6%.The optimum compounding method can produce stable emulsion with thick oil,and the viscosity can be reduced from 1 168.22 mPa·s to 57.57 mPa·s,with the viscosity reduction rate of 91.03%and the water separation rate of 21.33%.The organobase triethanolamine(TEOA)can reduce the interfacial tension of the compounded system to the 10-2 mN/m level.
