Figure M-VI 2.1 Crude oil Desalting. CRUDE OIL DISTILLATION. Desalted crude flows to atmospheric and vacuum distillation through crude pre flashing section. Atmospheric distillation column (ADU) and Vacuum distillation column (VDU) are the main primary separation processes producing various straight run products,
Crude oil contains salt, dissolved or suspended. The salt can lead to fouling and corrosion of heat exchangers and distillation overhead systems. Further salts are detrimental for catalysts in the downstream conversion processes. Excess of water has to be removed therefore desalting takes place before distillation.
This salt needs to be removed so that the crude oil can be processed in a refinery or stabilizer plant without fouling heaters and exchangers and other equipment. Crude Oil Desalting technology is utilised to remove residual salt to meet these requirements. The type and size of the Desalter that is used is dependent on.

When first received by a refinery, the crude oil usually contains some water, mineral salts, and sediments. The salt appears in different forms, most often times it is dissolved in the formation water that comes with the crude i.e. in brine form, but it could also be present as solid crystals, water-insoluble particles of corrosion
Desalting is a water-washing operation performed initially at the production field and thereafter at the refinery site for additional crude oil cleanup. Salt and water content specifications are even more rigid because of their negative effect in downstream processes due to corrosion, and catalyst deactivation. An optimum
ABSTRACT Electrical dehydration and desalting of crude oils are considered in terms of fundamental theory, laboratory studies and field operating expe rience with special attention directed at crude oils prodiked in Indonesia. The relative requirements of both crude oil producers and crude oil refiners for separation of water
