Abstract
System in fluid communication with an oil-contaminated water supply, such as a water leg portion of an offshore drilling or production platform sump tank, for conveying the separated water into contact with an organophilic clay in a vessel maintained at an operating pressure of at least 10 psig, such that the hydrocarbons and other organic material will be adsorbed onto the organophilic clay and will be conveyed back to the ocean water without contamination.
