Abstract
A petroleum desalting process is improved by introducing the an alkaline compound such as sodium carbonate into the water phase, preferably in the vicinity of the water/oil interface which forms between the oil and water layers. This makes the rapid and effective separation of the oil and water phases from the emulsion layer possible.
