Method for low temperature demulsification of thickened oil

一种用于稠油低温破乳的方法

Abstract

本发明涉及一种用于稠油低温破乳的方法,该方法通过引入破乳器,实现破乳剂在原油乳液中的有效扩散,采用一级加热、一次加破乳剂、一级沉降的方法,达到在较低温度下进行稠油脱水的目的。本发明的方法破乳效果好,特别适用于在较低温度下的稠油破乳。该方法工艺简单,设备数量少,操作简便,对破乳剂适应性较强,能在较低温度下实现高效快速脱除稠油中的水,从而达到大大降低能耗的目的。
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.
