Method for low temperature demulsification of thickened oil



The invention relates to a method for low temperature demulsification of thickened oil. According to the method, a demulsifier is introduced, a demulsifying agent is effectively diffused in crude oil emulsion, and the aim of dehydrating the thickened oil at a low temperature is achieved by adopting a method for performing primary heating, performing primary demulsifying agent addition and performing primary sedimentation. The method disclosed by the invention is good in demulsification effect and is particularly suitable for demulsification of thickened oil at a low temperature. The method is simple in process, small in equipment number, easy and convenient to operate and high in demulsifying agent adaptability, and water in the thickened oil can be efficiently and rapidly removed at the low temperature, so that the aim of greatly reducing the energy consumption is achieved.
