Salt Analyzer for Crude Oil

A non-transitory computer-readable storage medium having executable code stored thereon for determining the a salt concentration in crude oil, the executable code comprising a set of instructions that causes a plant information processor to perform operations comprising:

• obtaining one or more parameters associated with a desalting process, the desalting process parameters comprising a demulsifier flowrate, a crude oil temperature, a crude oil flowrate, a desalting electrostatic grids voltage, a wash water flowrate, and a disposal water flowrate;
• and
• determining the salt concentration in crude oil output from the desalting process using the one or more desalting process parameters
• comparing the determined salt concentration to a threshold concentration;
• and
• providing a notification if the salt concentration exceeds the threshold concentration.

A plant information system, comprising:

• a plant information processor;

• obtaining one or more parameters associated with a desalting process, the desalting process parameters comprising a demulsifier flowrate, a crude oil temperature, a crude oil flowrate, a desalting electrostatic grids voltage, and a wash water flowrate;
• and
• determining the salt concentration in crude oil output from the desalting process using the one or more desalting process parameters
• comparing the determined salt concentration to a threshold concentration;
• and
• providing a notification if the salt concentration exceeds the threshold concentration.
