Passive oil collection device

Abstract

A novel, efficient, economical oil collection device, which recovers oils from surface waters using physical principles has been demonstrated. This method has never been used in oil skimmers. The device contains a water-filled vessel open at one end that is positioned above the spilled oil so that the oil entrance opening is leveled with the oil layer on the water surface. The oil moves upward into the vessel displacing the water due to the lower density of the oil. The device has no moving parts. Torricelli’s discovery and Pascal’s law govern containment of the liquid in the vessel above the water level, while Archimedes’ buoyancy force moves oil in the vessel. A collection of thick and thin oil layers on calm water has been shown. This device is very durable, environmentally friendly, recovers pure oil, emits no noise, no pollution, and capable of producing a broad economic impact in the oil clean-up industry by protecting health, life, and the environment.
