Abstract
This invention discloses systems, apparatuses and methods for drying or dehydrating high moisture content feedstock to dry or low moisture products. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel and wherein the processing unit forms the dried material from the dryer vessel into granules, pellets, flakes or other desired form for the final product. The systems, apparatuses and methods of this invention also provide for prevention of release of HAP, including VOC, emissions from manufacturing facilities in conjunction with or independent of the above treatment of high water content feedstock.

16. A method for treatment of high water content feedstock in a manufacturing facility comprising:
-
operating a gas turbine producing exhaust gases; contacting the exhaust gases with high water content feedstock for a contact time sufficient to produce a dried material having a moisture content less than the feedstock; and directing HAP emissions produced in the manufacturing facility into the combustion air intake of the gas turbine, wherein the HAP emissions are from a different source than those produced by processing of the high water content feedstock. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
