  • Process for removing oils or petroleum from the surface of the sea
    Patent number: 4284509
    Abstract: After physical removal of the majority of the oil on the surface of the water, the thin film remaining is treated with microbial metabolites which reduce the surface and interface tension and cause the formation of oil agglomerates. These agglomerates may be drawn off or left to be degraded by hydrocarbon-degrading microorganisms normally present in the sea water or added thereto.
