A desalter is a course of unit in an oil refinery that removes salt from the crude oil. The salt is dissolved in the water within the crude oil, not in the crude oil itself. 200,000 tons of methanol installation The desalting is often the primary course of in crude oil refining. The salt content material after the desalter is often measured in PTB – pounds of salt per thousand barrels of crude oil. Another specification is Fundamental sediment and water
The time period desalter may additionally confer with a water desalination facility used to treat brackish water from agricultural runoff. This may be achieved either to provide potable water for human or animal consumption, or to scale back the salinity of river water previous to its crossing a world border, often to adjust to the terms of a treaty. Desalters are additionally used to treat groundwater reservoirs in areas impacted by cattle feedlots and dairies.

Desalting crude oil
The salts which are most regularly current in crude oil are calcium, sodium and magnesium chlorides. If these compounds are usually not removed from the oil several issues come up within the refining process. The high temperatures that happen downstream in the process could trigger water hydrolysis, which in flip permits the formation of corrosive hydrochloric acid. Sand, silts and salt cause deposits and foul heat exchangers or lead Petroleum Machinery manufacture to plugging. The need to supply heat to vaporize water reduces crude pre-heat capability. Sodium, arsenic and different metals can poison catalysts. By eradicating the suspended solids, they are not carried into the burner and finally flue gasoline, where they’d cause issues with environmental compliance akin to flue gasoline opacity norms.
