Demulsification of Crude Oil Emulsion Using Propylene Oxide-Ethylene Oxide Block Copolymer

Abstract:

Article Preview

The effect of concentration, temperature and pH-value on the demulsification potency of the propylene oxide and ethylene oxide block copolymer initiated from alkylphenol formaldehyde resin in breaking up emulsion from Daqing oilfield have been investigated. The results revealed that demulsification potency of the studied demulsifier increases with the increase of demulsifier at low concentration, the increase of temperature, the increase of acidic pH-value and the increase of demulsification time, respectively. In the meantime, demulsification potency of the studied demulsifier decreases with the increase of demulsifier at high concentration and the increase of basic pH-value, respectively. Neutral pH-value of the emulsion was found to be the optimum value causing maximum demulsification potency.
