Abstract:
Crude oil often contains different inorganic salts, such as chlorides of sodium, calcium, and magnesium. These salts are typically in the form of salt crystals dissolved in the water that is emulsified in the crude oil and bring various problems to petroleum refining industries. The large concentration of salt in crude can contribute to the mechanical cogging of furnace tubes, condensers, and lines via the formation of deposits. To avoid complications and corrosion during transport or storage, it is important to analyze the salt concentration in crude, so that the crude can undergo an appropriate desalting process before further progressing in the refinery process. The Koehler K23060 Salt in Crude Analyzer is an innovative, handheld instrument that can be intuitively used to measure the concentration of salts in crude oil. The instrument measures the conductivity of a solution of crude oil in a polar solvent and compares the result with a calibration curve of known salt mixtures, which will determine the salt content in the crude sample in accordance with ASTM D3230.
