ABSTRACT:
This invention comprises an apparatus or mechanism and a method of using it to recover petroleum from a floating slick or spill by means of absorbing the petroleum in powder particles principally comprising a reaction product of polyurethane, a catalyst, and a strong cationic polymer comprising an agent which produces a foam product that has a strong affinity for combining physically with petroleum resembling a magnetic attraction between the same. The reaction product is formed into desired sizes of elongated block-like shapes which are fed to a shredding assembly of saw blades that reduce the solid shapes into irregularly-shaped powder particles that are capable of being used in at least two ways to attract and adsorb petroleum by bonding. One way is to employ a porous boom of substantial diameter and length that is used to at least partially enclose a predetermined area of the slick or spill, the particle content of the boom absorbing adjacent petroleum. A second way of using the particles is to discharge them from a blower or otherwise dispose them onto the area of slick which is partially or completely surrounded by the boom to permit the particles to absorb the area of the slick subtended by the boom into the deposited particles, either with the boom also absorbing the petroleum or not. The adsorbed particles then are moved to a conveyor on a ramp which moves them to a high-powered centrifuge that operates at high speeds that are capable of breaking the attraction or bond of the particles to the petroleum and thereby separates the petroleum for recovery thereof and renders the released particles available for reuse.
