the salt content in crude oils. Its technology is based on ASTM D 3230, an electrometric
method. This method determines the salt concentration in crude oil by measuring its
conductivity, when dissolved in a mixture of an aromatic and an alcoholic solvent.

the refinery operation only, but is also
essential from a commercial point of
