Desalters

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 EN-FAB desalter provides efficient separation of undesirable impurities, suspended in crude feedstocks.

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

• EN-FAB desalters efficiently remove undesirable impurities, especially salts and water, from crude oil prior to distillation.

• Inorganic salts can become decomposed in crude oil preheat 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.
