gravity separation of three phases: gases, crude oil and water (with entrained dirt). CRUDE DESALTING. It is a water washing operation performed at the refinery site to get additional crude oil clean up. • Crude Oil Desalting consists of. • Purifying process. • Remove salts, inorganic particles and residual water from crude oil.
Crude Oil Pretreatment (Desalting). Petroleum refining is the process of separating the many compounds present in crude petroleum. Desalting Process.

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.
When crude oil enters the unit, it carries with it some brine in the form of very fine water droplets emulsified in the crude oil. ? Desalting of crude oil is an essential part of the refinery operation. ? The salt content should be lowered to between 5.7 and 14.3 kg/1000 m3. 2
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
system in the crude oil washing process. The evaluation was carried out in the two desalters at the. Cartagena Refinery (GRC) and a desalter at the Barrancabermeja Refinery (GCB) of ECOPETROL. The pressure drop was measured and the efficiency of the desalting processes, dehydration and hydrocarbon crude.
?to reduce corrosion, plugging, and fouling of equipment and. ?to prevent poisoning the catalysts in processing units, these contaminants must be removed by desalting (dehydration). Page 4. 4. The two most typical methods of crude-oil desalting are: Chemical desalting. ?water and chemical surfactant. (demulsifiers) are
Full-Text Paper (PDF) | 10.5772/61274 | 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
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.
