An air modulated vacuum oil recovery technique was developed in an experimental and engineering design project as a method of collecting oil spilled on water. A foam is produced using foaming agents in order to facilitate the removal. The prototype device possessing a self contained power source proved capable of rapidly recovering thin slicks of oil (less than 4 mm) from water surfaces with only a small amount of water present (less than 10% by volume) in the recovered oil. The prototype recovered oil at the rate of 450 gal/hr for a thin oil slick. Thicker slicks could be recovered much more rapidly. The process and laboratory equipment is described.
