Abstract
The invention relates to removing salt from crude oil via two steps of adding water with harsh mixing of the added water with the crude oil and gravity separating the salty water between steps where the process additionally includes a step of injecting steam into the crude oil after the first of the two water adding and harsh mixing desalting steps, but upstream of the gravity separation of the first step. The steam separates salt by transferring the salt into the condensed water from the steam.
