原油的脱盐脱水工艺
摘要：
本发明公开了一种原油的脱盐脱水工艺，包括以下步骤：向原油中注入6.5%的新鲜水并充分混合，使悬浮在原油中的盐粒能够充分的溶解于新鲜水中，然后加入适量的破乳剂，在高压电场的作用下以及120-145℃温度条件下，进行一次分离，使大部分的盐和水从原油中分离出，将经过一次分离后的原油引至二次分离罐中进行二次分离，其中，二次分离的工艺条件为：高压电场、110-125℃。本发明所述的原油脱盐脱水工艺通过二次分离，且对两次分离中的工艺条件进行控制，从而实现脱盐脱水效果较好的原油处理工艺。
摘要（英）：

The invention discloses a crude oil desalting and dewatering technique which comprises the following steps: injecting 6.5% of fresh water into crude oil, sufficiently mixing until salt particles suspended in the crude oil can be sufficiently dissolved in the fresh water, adding a proper amount of demulsifier, carrying out primary separation at 120-145 DEG C under the action of a high-voltage electric field to separate most salts and water out of the crude oil, and leading the crude oil subjected to primary separation into a secondary separation tank to perform secondary separation at 110-125 DEG C in a high-voltage electric field. The crude oil desalting and dewatering technique is implemented by the two separation processes, and implements favorable desalting and dewatering effects by controlling the technological conditions in the two separation processes.
