Process and system for drying and heat treating materials
First Claim
1. A method for treatment of waste material feedstock comprising:
- operating a gas turbine generator to produce electricity and exhaust gases having a temperature greater than 1,000°
F.;
contacting the exhaust gases having a temperature greater than 1,000°
F. with waste material feedstock having a moisture content of at least about 30% by weight in a dryer vessel for a contact time sufficient to produce without significant oxidation of the waste material feedstock a dried material having a moisture content of less than about 20% by weight.

Abstract
This invention discloses systems and methods for conversion of high moisture waste materials to dry or low moisture products for recycle or reuse. 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 or other desired form for the final product. Optionally, the systems and methods further provide for processing ventilation air from manufacturing facilities to reduce emissions therefrom.
