Abstract

A sorbent and filter media material produced from a mass of delustered hydrophobic and lipophilic fibers. In one embodiment the fibers are mixed together to form a cohesive wad of fibers. The wad has a substantial volume of internal interstices available to absorb a liquid hydrocarbon or an organic liquid, and the surfaces of the fibers also adsorb that liquid. The combination of adsorption and absorption enables the sorbent to sorb up to twenty times it own weight of hydrocarbon or organic liquid. Preferably a majority of the fibers are of a relatively shorter length, while a minority of the fibers are of a relatively longer length. The longer fibers help bind the wad together into a cohesive mass that has a substantial volume of internal interstices. After a short time during which the hydrocarbon is sorbed, the wadded mass can be collected, pressed to recover the hydrocarbon, and recycled.

         86 . The delustered fiber filter of  claim 83 , wherein said delustered fiber filter does not substantially impede a flow of water through said delustered fiber filter.  
     
     
         87 . A method for removing at least one of an organic liquid and a liquid hydrocarbon from a surface of a body of water contaminated with one of the organic liquid and liquid hydrocarbon, comprising the steps of: 
 (a) providing a hydrophobic and lipophilic sorbent product that is encased in a porous encapsulating boom, said hydrophobic and lipophilic sorbent product comprising a plurality of delustered hydrophobic and lipophilic fibers;    (b) collecting the liquid hydrocarbon by: 
 (i) encircling a portion of the surface of the body of water with the sorbent filled porous encapsulating boom, said portion encompassing all of the surface of the body of water that is contaminated;  
 (ii) allowing the sorbent filled porous encapsulating boom to sorb at least a portion of said one of the organic liquid and the liquid hydrocarbon from the surface of said body of water;
