ABSTRACT:
Oil-separation and recovery from marine oil spills is carried out by a system which includes a containment boom, a weir and/or foil type skimmer, a separator unit and a second, fire proof containment boom for receiving separated oil in a closed containment area on the surface of the body of water from which the oil has been recovered and wherein the oil may be combusted. The separator unit uses so-called superabsorbent materials including sheets of non-woven fibers or flakes of materials including sodium carboxymethyl cellulose, acrylonitrile grafted starch absorbents, polyacrylates, copolymers of styrene and maleic anhydride and copolymers of unsaturated monomers and recurring units of at least one copolymerizable comonomer comprising about 20% to about 80% pendant carboxylic acid units and about 80% to about 20% pendant carboxylate salt units blended with a monomer containing at least two hydroxyl groups. The separator unit includes a tank with spaces defined in part by the sheets of absorbent materials disposed such that water may flow through the absorbent sheets and oil is collected and removed from one side of the space defined by the sheets.
