Abstract
A system and method for passive collection of oil from water based on a density differential. A sealed column of water is elevated above the oil/water surface within a low pressure contained volume, and oil moves upward into the contained volume displacing the water due to the lower density of the oil. Filled containers of oil are exchanged for containers of water, or oil is transferred from the filled containers.
