FREMGANGSMAATE FOR REDUSERING AV SALTINNHOLDET I RAAOLJE

The salt content of crude oil is reduced by washing crude oil containing residual salt water with wash water of lower satinity than the water present in the crude oil and allowing the resulting mixture to settle into a layer of crude oil of reduced salt water content and a layer of saline water.

Beschreibung
Zusammenfassung:	The salt content of crude oil is reduced by washing crude oil containing residual salt water with wash water of lower satinity than the water present in the crude oil and allowing the resulting mixture to settle into a layer of crude oil of reduced salt water content and a layer of saline water. The quantity of wash water employed is greater than 7.5% by volume of the crude oil.The saline water may be recycled and a proportion removed from the recycle stream and a corresponding quantity of water of lower salinity added.Washing with relatively large quantities of water results in the formation of a less stable emulsion. Consequently, less severe conditions are required to break it to recover the desalted crude oil.
