Demulsification of Crude Oil
1. Feasible to capture the rate @ which both elasticity and interfacial viscosity changes as demulsifiers gradually start replacing emulsifiers within oil-water interfacial film @ lab-scale?
2. Whether the rate @ which the strength and life time of interfacial film keeps mitigating upon the addition of demulsifiers remain linear?
If so, what is the respective rate @ which, the curve of interfacial elasticity would keep changing upon enhancing the concentration of demulsifiers?
Would it change continuously?
OR
Will it reach asymptoticity upon reaching critical concentration of demulsifiers?
3. How exactly emulsion stability gets disturbed as a function of demulsification pressure upon reducing the rig pressure beyond bubble point pressure?
4. Whether amine group demulsifiers (hexylamine/diacylamine) would remain to be more effective than acid group and polymeric emulsifiers in breaking emulsion in carbonate reservoirs?
5. If emulsion formation and its associated stability keep varying from one location to another (even between two different wells in the same field); on top of having safety concerns; being expensive; and not being environmental friendly, then, why do we still (mostly) prefer chemical demulsification technique to remove water from crude oil as against using electrical or thermal (centrifugal/micro-wave/ultra-sonic) demulsification techniques?
