ABSTRACT:
A method for recuperating crude oil from the body of a spill. First, the body of the spill is sprayed at low pressure then the same operation is done at a relatively higher pressure of at least 100 p.s.i. After the dispersant is allowed to penetrate the body of the spill for several hours, physical agitation of the body of the spill is induced the use of air compressors operating in the range between 500 and 700 psi causing the crude oil to disperse and come to the surface. The crude oil is then extracted from the spill through the use of skimmers and vacuum suction means and subsequently processed.
