Abstract: An improved separator for desalting petroleum crude oils which may be operated in a continuous manner under automatic control; the improved desalter is therefore well suited to modern refinery operation with minimal downtime. A portion of the emulsion layer is withdrawn from the desalter through external withdrawal ports according to the thickness and position of the emulsion layer with the selected withdrawal header(s) being controlled by sensors monitoring the position and thickness of the emulsion layer. The withdrawn emulsion layer can be routed as such or with the desalter water effluent to a settling tank or directly to another unit for separation and reprocessing.

Abstract translation: 一种改进的脱盐石油原油分离器，可在自动控制下连续运行; 因此，改进的脱盐器非常适合现代炼油厂的运行，停机时间最短。 乳剂层的一部分根据乳液层的厚度和位置通过外部取出口从脱盐器中排出，所选择的取出头由监测乳剂层的位置和厚度的传感器控制。 抽出的乳剂层可以这样或者与脱盐水流出物一起排列到沉淀池中或直接传送到另一个单元进行分离和再处理。
