An oil processing vessel for cleaning oil and the associated produced water utilizing the principle of capillary attraction in lieu of heat and/or electric coalescence to dehydrate the oil and in lieu of induced gas flotation to extract oil from the water. The oil processing vessel also includes a means for mitigating the foam often encountered when processing crude oil and if required an integral means to split the oil discharge from the vessel into disparate proportional flow streams. There also can be included a means for extracting extraneous material that accumulates inside the vessel at the water/oil interface.
