Desalter working principle in Oil Refinery.

An oil refinery desalter works by mixing crude oil with water to break the oil-water emulsion.

The mixture then enters an electrostatic chamber where an electric field helps water droplets coalesce.

The coalesced water settles at the bottom, separating from the oil.

The partially desalted oil then undergoes dehydration to remove any remaining water.

Throughout the process, parameters like water-to-oil ratio, voltage, and temperature are adjusted to optimize desalting efficiency.

The desalter's purpose is to remove impurities like salts and water from crude oil, improving product quality and preventing corrosion in downstream refining units.
