3 Most Common Methods Of a Crude Oil Desalter
A crude oil desalter is a machinery tool utilized in the oil refinery industry to remove inorganic salts, water, and sediments from the impure petroleum crude oil. Removal of salts, water and sediments is a necessary activity to prevent corrosion that occurs from hydrochloric acid generation. It is a result of the hydrolysis of chloride salts present in the crude oil (calcium chloride and magnesium chloride). Any salt that remains even when the process is complete, represents a metal source that can poison expensive catalysts useful in a variety of petroleum refinery processes. Most common methods of crude oil desalting: • Chemical And Electrostatic Separation: Washing off the salt from crude oil with the help of water oil and water phases are separated with the application of a settling container. In the next step, chemicals are mixed to break down the emulsion or electrostatic field can be applied to subside the saltwater droplets more rapidly. • Electric Desalting: Unde...
