can be removed in Desalter, but small amounts of salt may be dissolved in the crude oil itself. The salts that are most frequently found present in crude oil feed stocks are sodium, calcium and magnesium chlorides (NaCl, CaCl2 and MgCl2) although other forms of salt can be present in smaller quantities.

Crude Oil Desalting | Emulsion | Sodium Chloride

Crude Oil Desalting. Introduction When the crude oil enters the unit, it carries with it some brine in the form of very fine water droplets emulsified in the crude oil. The salt content of the crude measured in pounds per thousand barrels (PTB) can be as high as 2000. Desalting of crude oil is an essential part of the refinery operation. The salt content should be lowered to between 5.7 and 14 ...

Alfa Laval - Crude oil desalting

Desalter - Wikipedia

A desalter is a process unit in an oil refinery that removes salt from the crude oil. The salt is dissolved in the water in the crude oil, not in the crude oil itself. The desalting is usually the first process in crude oil refining. The salt content after the desalter is usually measured in PTB - pounds of salt per thousand barrels of crude oil.

Desalting Optimization | Baker Hughes, a GE Company

The typical response to desalter upsets is to increase demulsifier pump rates, but that is inefficient and costly in terms of chemical, since actual demulsifier usage during upset conditions far outpaces target dosages. By stabilizing the feed and preventing upsets, chemical demand is steady and predictable, and overall program costs are lower.
