Process and system for drying and heat treating materials
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.
1. Apparatus for treating waste material feedstock comprising:
a gas turbine;
a dryer vessel receiving exhaust gases from the gas turbine through a connection, receiving waste material feedstock and drying or thermally treating the waste material feedstock by direct contact of the exhaust gases and the waste material feedstock to produce a converted material, wherein the connection between the gas turbine and the dryer vessel substantially precludes the introduction of air into the dryer vessel; and
a processing unit receiving the converted material from the dryer vessel and forming same into granular, pellet or prill form.
2. Apparatus according to claim 1 wherein the gas turbine comprises a gas turbine generator.
3. Apparatus according to claim 1 wherein the connection between the gas turbine and the dryer vessel directs essentially 100% of the gas turbine exhaust into the dryer vessel.
4. Apparatus according to claim 3 wherein the gas turbine comprises a gas turbine generator.
