Methods and systems for proactively monitoring crude quality assurance

A non-transitory computer-readable storage medium having executable code stored thereon for controlling the processing crude oil, the executable code comprising a set of instructions that causes a processor to perform operations comprising:

• obtaining a first voltage associated with a desalter of a crude oil processing system;
• obtaining a second voltage associated with a dehydrator of a crude oil processing system, wherein an output stream from the dehydrator is provided to the desalter;
• evaluating at least one of the first voltage and the second voltage as an indicator of the salt concentration in crude oil;
• and
• adjusting at least one of a plurality of control parameters in response to the evaluation to modify at least one of a separation efficiency of the high pressure production trap (HPPT) of the crude oil processing system and a separation efficiency of the dehydrator,
• the plurality of control parameters comprising a wash water parameter, a demulsifier parameter, an interface level of the dehydrator, an interface level of the desalter, and a mixing valve parameter, wherein the mixing valve parameter comprises a differential pressure across a mixing valve positioned to mix wash water, a demulsifier, and the dehydrator output stream.
