Serving the Oil & Gas Industry Since 1980


When crude oil is brought to the surface by whatever means, it contains many undesirable impurities, including salts, suspended solids and water soluble trace metals/slits, iron oxides, sand etc. The salt content in the crude oil varies depending on source of the crude oil.  When a mixture from many crude oil sources is processed in refinery, the salt content can vary greatly.


The Purpose of Desalting

  • Removal of undesirable impurities, especially salts and water, from the crude oil prior to distillation.


  • Inorganic salts can become decomposed in crude oil pre-heat exchangers and heaters. As a result, hydrogen chloride gas is formed which condenses to liquid hydrochloric acid at overhead system of the distillation column, damaging expensive internals and downstream equipment.


  • Sand or silt can cause significant damage due to abrasion or erosion to pumps, pipelines, etc.


  • The calcium naphthanate compound in the crude unit residue stream, if not removed can result in the production of lower grade coke.


  • To remove Metals which may poison the Reformer Catalyst.


  • To avoid lengthy and expensive plant shut downs and achieve more then average Plant Life.



EN-FAB Crude Desalters, Early Production Facility

The crude oil distillation unit is the first processing unit in virtually all petroleum refineries, distilling the incoming oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units.
