ABSTRACT:
A method of recovering oil floating on a water surface which has been contaminated with the oil by distributing upon the contaminated surface discrete particles of a hydrophobic macroporous highly crosslinked polymer. The particles are allowed to adsorb and to become laden with the oil. The oil laden particles are recovered from the water surface, and the oil from the oil laden particles is removed by applying compressive forces to the oil laden particles. Particles which are substantially free of the oil are recirculated and re-distributed upon the contaminated surface, and this sequence of steps is repeated until substantially all of the oil has been recovered.
