Salt Analyzer for Crude Oil Using Process Parameter Model

The patent creates a virtual copy of the physical desalting process by developing a mathematical model that replicates salt concentration behavior. The model uses process parameters (electrostatic voltage, water flow rates, demulsifier injection) to generate a virtual representation of salt concentration that correlates with actual measurements, eliminating the need for frequent physical sampling while maintaining measurement accuracy.

The patent replaces the mechanical/chemical manual sampling and titration system with a computational model-based system. Instead of physically collecting crude oil samples and performing laboratory titration, the system uses a computer-implemented model that calculates salt concentration based on process control parameters, substituting physical measurement operations with computational analysis.

The patent implements continuous monitoring by having the model calculate salt concentration continuously based on continuously updated process parameters from the desalting system. Instead of periodic discrete measurements, the model provides ongoing real-time assessment of salt concentration, enabling immediate detection and response to quality changes while maintaining ease of operation through automated calculations.

The patent establishes a feedback loop where the model continuously receives process parameter data from the desalting system, calculates salt concentration, and provides this information back to operators. This feedback mechanism enables real-time monitoring and allows for immediate process adjustments to maintain salt concentration within specifications, improving response time while keeping the system easy to operate.
