Hydrocarbon-in-water purification system

Abstract:

A hydrocarbon-in-water purification system includes a high capacity hydrocarbon absorber stage having a high capacity hydrocarbon absorber material and an inlet configured to receive a hydrocarbon-in-water dispersion from a fuel system. A polishing hydrocarbon absorber stage is in liquid communication and downstream of the high capacity hydrocarbon absorber stage including polishing activated carbon. The high capacity hydrocarbon absorber material has a greater saturation capacity than the polishing activated carbon and the polishing activated carbon has a greater polishing capacity than the high capacity hydrocarbon absorber material. A method for controlling and managing the evacuation of water from the hydrocarbon-in-water purification system includes tracking the purification state of water volumes and the bed loading states of purification beds defined in the water filter.
