Abstract�� In consideration of thermochemical method in demulsification of high water-content crude oil,the influences of temperature and quantity of demulsifier on the demulsification efficiency and demulsification velocity were investigated.It is shown that for a fixed amount of crude oil,there is an optimum quantity of demulsifier and it is affected by temperature.The optimal quantity of the demulsifier for crude oil decreases with the increase of temperature.The quantity of demulsifiers can also affect the dehydration velocity of the emulsion.
