The salts in crude oils are very important topic. they must be removed in the desalter by many methods. what are these salts?
Dear Anirbid Sircar,
Thank you for the informations. We need know the normal ranges quantities of each salt in most known oils.
regards!

The chemical composition of these salts varies, but nearly always is mostly NaCl, with lesser amounts of calcium and magnesium chloride.
(petrowiki)
Mostly chlorides and minor amount of sulphates, of sodium, calcium, however it is better to do a full scale ionic analysis of produced water to identify the known elements and its concentration. you will require to know the FEED quality of your crude for designing desalter. Moreover these salts make water more corrosive to carbon steel so this factor also to be considered from metallurgical point of view.
