3 Phase Separator P&ID
This P&ID illustrates a 3-phase horizontal separator vessel that receives a mixed 3-phase inlet stream and separates it into vapor, oil, and water. The vessel is equipped with vortex breakers, a weir, and a demister pad. Control strategies include a pressure control loop for the vapor outlet, and two separate level control loops for managing the water and oil levels and their respective outlets.
