ABSTRACT:
An organoclay made by the reaction of smectite clay and a quaternary ammonium compound derived from an oil having 50% or more of its carbon chain lengths consisting of C.sub.14 or lower is described as an effective oil spill remediation agent. Oils used include coconut, babasso and palm-kennel oil. Such organoclay's effectiveness as an oil spill remediation agent, and that of organoclays can be increased by (a) further treatment with a water insoluble compound such as vegetable oil and b) by mixture with an organic fibrous material such as waste paper pulp. The agents produced are particularly effective in polar and arctic waters in maintaining buoyancy of the oil agglomeration formed by their use. Methods of remediating oil spills using organoclays particularly useful in regions such as waters of the Alaska oceans and inlets of the North Sea are also described.
