IS 1448 : Part 115 : 2023 Petroleum and Its Products - Methods of Test Part 115 Determination of Salt Content in Crude Oil
Revised Standard from Last Update.
1. SCOPE
1.1 This standard prescribes three test methods for determination of salt content in crude oil that is conductometric method, extraction method and ion chromatography method.
1.2 Method A covers the determination of the chloride (salts) concentration in crude oil. The range of concentration covered is 3.5 mg/kg to 500 mg/kg as chloride concentration/volume of crude oil.
1.2.1 This method measures conductivity in the crude due to presence of common chlorides, such as sodium, calcium, and magnesium. Other conductive materials present in the crude oil may also contribute to the conductivity.
1.3 Test method B is intended for the determination of total halide concentration of 0.002 percent to 0.02 percent, weight in crude petroleum, topped crude, residual cracking stock, and fuel oil. It may also be applied to the estimation of seawater contamination of used turbine oil and of marine diesel fuel.
1.4 Test method C for salt content in crude oil using extraction by hot water with mechanical stirring and detection by ION chromatography technique. The method covers the concentration of salt measurement start from 0.1 PTB and above.
