can be removed in Desalter, but small amounts of salt may be dissolved in the crude oil itself. The salts that are most frequently found present in crude oil feed stocks are sodium, calcium and magnesium chlorides (NaCl, CaCl2 and MgCl2) although other forms of salt can be present in smaller quantities.

Crude Oil Desalting | Emulsion | Sodium Chloride

Crude Oil Desalting. Introduction When the crude oil enters the unit, it carries with it some brine in the form of very fine water droplets emulsified in the crude oil. The salt content of the crude measured in pounds per thousand barrels (PTB) can be as high as 2000. Desalting of crude oil is an essential part of the refinery operation. The salt content should be lowered to between 5.7 and 14 ...

Coalescer - Wikipedia

A coalescer is a technological device performing coalescence.They are primarily used to separate emulsions into their components via various processes; operating in reverse to an emulsifier.. There are two types of coalescers. Mechanical coalescers use filters or baffles to make droplets coalesce while electrostatic coalescers use DC or AC electric fields (or combinations).

A small-scale dynamic simulator for crude oil refinery desalters has a pressurized oil deviblis configured to hold a supply of crude oil and a water deviblis configured to hold a supply of wash water. At least one chemical feed pump selectively adds emulsion breaker chemicals to the desalter simulator and a low shear metering pump is configured to pump crude oil and wash water through the ...

Desalting Optimization | Baker Hughes, a GE Company

The typical response to desalter upsets is to increase demulsifier pump rates, but that is inefficient and costly in terms of chemical, since actual demulsifier usage during upset conditions far outpaces target dosages. By stabilizing the feed and preventing upsets, chemical demand is steady and predictable, and overall program costs are lower.

Desalter - Wikipedia

A desalter is a process unit in an oil refinery that removes salt from the crude oil. The salt is dissolved in the water in the crude oil, not in the crude oil itself. The desalting is usually the first process in crude oil refining. The salt content after the desalter is usually measured in PTB - pounds of salt per thousand barrels of crude oil.

A delicate balance must be maintained while controlling mixing intensity and feed levels to provide optimal salt removal. The fluid-handling equipment supporting the Desalter must be reliable and robust enough to withstand aggressive levels of corrosive and abrasive wear‚ as well as the arduous start and stop cycling of this intermittent duty.

desalter. The desalted crude enters another heat exchanger network. Both heat exchanger networks make use of the vapors of the main column condenser, the pump-around circuit streams (PA1, PA2 and PA3), and the products that need to be cooled. Then, the preheated crude enters the furnace, where it is heated to about 340-372 oC (644-700 oF).
