Salts in crude oil are the main reason of overhead corrosion in distillation column. Common salts in crude oil are NaCl, MgCl2, CaCl2. The hydrolysis of MgCl2 starts about 120C and hydrolysis of CaCl2 starts about 210C. Because of hydrolysis HCl forms which causes overhead corrosion. The final results for various samples show a salt content (ppm) of crude oil (307.32 – 441.58) ppm, diesel (19.68 – 579.27) ppm, kerosene (102.02 – 531.94) ppm, gasoline (92.76 – 563.76) ppm, turbine oil (recycled) 30.77 ppm and turbine oil (used) 324. 1.1 This test method covers the determination of the approximate chloride (salts) concentration in crude oil. The range of concentration covered is 3.5 mg/kg to 500 mg/kg or 1.0 lb/1000 bbl to 150 lb/1000 bbl (PTB) as chloride concentration/volume of crude oil. Assuming a crude oil sg=0.9, and that measured Cl is 10 ppm w/w, NaCl content can be calculated as follows: NaCl content =10*1.65=16.5 ppm w/w. Volume of 1000 bbl=159 m3.

The range of concentration covered is 0 to 500 mg/kg or 0 to 150 lbs/1000 bbl as chloride concentration/volume of crude oil. 1.2 This test method measures conductivity in the crude oil due to the presence of common chlorides, such as sodium, calcium, and magnesium. Other conductive materials may also Salt Content. Salt content of crude oils can be measured using the standard method ASTM D3230 and reported as lb NaCl/1000 bbl. Desalting (removing the salt) is necessary when NaCl content is greater than 10 lbs/1000 bbl. Such high salt contents lead to corrosion in distillation towers and other equipment.

Continuous monitoring of the salt content by the MOD 4100 S Salt in crude oil analysers, is highly beneficial to guarantee the highest degree of desalting at lowest cost of operation, also including reducing the amount of wash water to its minimum. Reducing the salt content also influences the salt point.
Salt content (measured as sodium chloride) in electrically desalted crude oil comes down to a level of about ______ ptb (pounds per thousand barrel). a) 0.03 b) The crude oil is in the form of a water-in-oil emulsion with water content of 8% (by weight) or less. The salt is stirred into the crude oil. The resulting mixture is

For the purpose of this test method, salt is expressed as % (m/m) NaCl (sodium chloride) and covers the range from 0.0005 % to 0.15 % (m/m).
