Abstract

Systems and methods for treating a rag layer in a gas oil separation plant. The method includes withdrawing the rag layer from a vessel proximate an oil water interface; conveying the rag layer to a separation device, the separation device operable to effect electrostatic coalescence on the rag layer to separate oil and water; and recycling separated oil from the separation device back to the gas oil separation plant process.
