Background

The crude oil entering the refinery, although being dewatered at the field, still contains a greater or lesser amount of salt and water. The salts (such as sodium chloride, calcium chloride, magnesium chloride and the like) contained in the crude oil are mostly dissolved in water to form water-in-oil emulsion; also a small fraction of salt crystals are suspended in the oil. In order not to affect the crude oil processing, the crude oil is desalted and dehydrated in the first step after entering the plant. The method for removing the crude oil is to add a small amount of water (about 5 percent) to be fully mixed, to make salt completely dissolved in the water, then to add a selected demulsifier, to make water drops grow under the action of an electric field and obtain sedimentation separation under a certain condition (the temperature is properly high to reduce the crude oil temperature, and the pressure is higher than the temperature by F and the saturated vapor pressure of the oil is 0.1-0.35 MPa). This process is known as desalting and dewatering of crude oil. Desalting and dewatering are carried out simultaneously.
