ABSTRACT:
An oil spill recovery system includes a first hydrocyclone separator and optionally a second hydrocyclone separator located on a floating vessel floating on a body of water from which spilled oil is to be recovered. A recovered fluid containing oil and water emulsion and a large amount of free sea water is recovered from the body of water. The first hydrocyclone separator separates the recovered fluid into a first underflow stream containing oily water and a first overflow stream which contains substantially all of said oil and water emulsion. The oily water underflow stream from the first hydrocyclone separator is then directed to a second hydrocyclone separator which separates it into a second underflow stream which is returned to the sea as clean water, and a second overflow stream. The first overflow stream is stored in on-board ship's storage. The second overflow stream may be stored in ship's storage or recycled for further separation.
