Water free pulp from pulp slurry

Abstract

By providing a pulp slurry, containing ink and water, and subjecting the slurry to dewatering to produce pulp sludge containing water is formed and a liquid, primarily water, is obtained. Pulp sludge, removed from dewatering is subjected to pressing to produce pressed pulp and expelled water. The expelled water and liquid, primarily water, is combined and recycled to an apparatus to create additional pulp slurry. Dewatered pressed pulp is subjected to dehydration, to transfer water contained within pulp, to air. Pulp resulting from dehydration is then subject to bailing. Furthermore pulp is excluded from a deinking procedure to permit ink to remain within the pulp. Whereby this invention removes water from a pulp slurry and provides pulp substantially devoid of water.

What is claimed is:  
     
         1 . A method to separate pulp from an aqueous pulp slurry, which comprises: 
 providing a pulp slurry containing ink and water, and    providing dewatering means, and    subjecting said pulp slurry to said dewatering means to form pulp sludge and a liquid primarily water, and    removing said pulp sludge and said liquid from said dewatering means, and subjecting said pulp sludge to dehydration to transfer water within the pulp sludge to form pulp substantially devoid of water, and    creating additional pulp slurry containing ink and water from said liquid whereby this invention removes water from a pulp slurry and provides pulp substantially devoid of water.    
     
     
         2 . The method as described in  claim 1  wherein said pulp slurry is obtained from waste paper.  
     
     
         3 . The method as described in  claim 2  wherein the pulp slurry contains ink from waste paper.  
     
     
         4 . The method as described in  claim 2  wherein the waste paper is selected from the group of, newspapers, office papers and cardboard including an individual or a combination thereof.  
     
     
         5 . The method as described in  claim 1  wherein said pulp, substantially devoid of water, is subjected to bailing to form bales of pulp.  
     
     
         6 . The method as described in  claim 1  wherein said pulp slurry is produced from waste paper within an apparatus for pulping.  
     
     
         7 . The method as described in  claim 1  wherein said pulp, substantially devoid of water, is subjected to gasification.  
     
     
         8 . The method as described in  claim 7  wherein gasification from the pulp is used to power fuel cells.  
     
     
         9 . The method as described in  claim 8  wherein the fuel cells are selected from the group consisting of molten carbonate fuel cells, solid oxide fuel cells or a combination thereof.  
     
     
         10 . The method as described in  claim 8  wherein the fuel cells are stationary within a site.  
     
     
         11 . The method as described in  claim 1  wherein said pulp slurry is produced from cellulose solids.  
     
     
         12 . The method as described in  claim 1  wherein said pulp slurry is separated from matter unaffected by pulping.  
     
     
         13 . The method as described in  claim 1  wherein said pulp is obtained from waste paper contained within municipal solid waste.  
     
     
         14 . The method as described in  claim 1  wherein said method is accomplished in batch form as well as by a continuous form.  
     
     
         15 . The method as described in  claim 1  wherein said pulp sludge is subject to dehydration by air.  
     
     
         16 . The method as described in  claim 1  wherein said pulp sludge is subject to dehydration by a drier.  
     
     
         17 . The method as described in  claim 1  wherein said pulp slurry is produced from an apparatus to create additional pulp slurry.  
     
     
         18 . The method as described in  claim 1  wherein said pulp slurry contains organic compounds.  
     
     
         19 . The method as described in  claim 1  wherein said dewatering means is a filter to produce filtered pulp and an aqueous filtrate.  
     
     
         20 . The method as described in  claim 1  wherein said dewatering means is a filter press to produce pressed pulp and an expelled liquid, primarily water.
