Abstract
A method and apparatus for determining the salt concentration of crude oil using a single solvent that allows for improved safety and accuracy. The apparatus can include a pair of electrodes, a solvent storage container, a power source, a temperature sensor, a computer, and a display device. The method includes introducing a volume of the crude oil and a solvent to a mixing zone and mixing them together to form a homogenized mixture. The temperature and conductivity of the homogenized mixture are measured in order to determine the salt concentration of the homogenized mixture, and subsequently, the salt concentration of the crude oil.
