A method for determining a salt concentration of a hydrocarbon fluid using a conductivity sensor and a hydrocarbon testing solution includes forming the hydrocarbon testing solution. The electropolymerizable monomer is operable to form a resultant associated polymer at a peak potential of the electropolymerizable polymer. The method includes introducing the hydrocarbon testing solution into the conductivity sensor. The method includes inducing a range of potential across the hydrocarbon testing solution such that at least a portion of the electropolymerizable monomer polymerizes. The range of induced potential includes the peak potential of the electropolymerizable polymer. The method includes detecting a range of electrical current associated with the range of potential induced. The method also includes the step of determining the salt concentration of the hydrocarbon fluid using the range of potential induced and the range of electrical current detected.
A conductivity sensor useful for determining the salt concentration of a hydrocarbon testing solution by forming a resultant associated polymer, the conductivity sensor comprising:
A hydrocarbon testing solution useful for determine a salt concentration in a hydrocarbon fluid comprises the hydrocarbon fluid, an electropolymerizable monomer and a non-aqueous solvent, where the hydrocarbon fluid comprises a salt and a hydrocarbon selected from a group consisting essentially of a crude oil, a natural gas condensate, a crude oil fraction, a post-petrochemical processed material and combinations thereof, and where the electropolymerizable monomer is operable in the hydrocarbon testing solution to form a resultant associated polymer at a peak potential of the electropolymerizable polymer.
