Gasification Process

With this process, tires are shredded on receipt to a minus 2 x 2 particle size through the use of a mobile shredder and transported to the manufacturer's processing installation. These tire chips are fed into the gasifier retort by means of a closed feed hopper and auger system. The gasifier is a closed system. It is designed to be pollution and emission free. From the retort, the gas is directed into mechanical cleaner and cooling modules, and from there into an electrostatic precipitator for fine particulate removal. All contaminants such as complex sulfur compounds, dioxins, furans and zinc oxides are removed and chemically neutralized or modified. The cleansed gas product is then immediately available and ready for economic use and may be introduced directly into electric energy production or other heating applications.

The average weight of a worn passenger car tire is approximately 20 lb., of which 2 to 3 lb. is #2 scrap steel, approximately 2 lb. may be fabric, and the remaining 15 to 16 lb. is the petroleum base product in different compounds. 1-lb. of shredded tire produces approximately 13,500 BTUs, or 45 ft.³, of synthetic tire derived gas.
