Waste Tyre Management
VIPAR ENGINEERING
PYROLISIS PLANT
INNOVATIVE DESIGN WITH LOW INSTALLATION COST AND HIGHER EFICIENCY
Technology
Pyrolysis involves heating waste tyres /plastic without oxygen to break them down to char or carbon black, oil, and gas. Plants operate within a temperature range of 250° - 500°C.At temperatures above approximately 150°C tires release increasing amounts of liquid oil products and gases. Above 400°C, depending on the process employed, the yield of oil and solid tire-derived char may decrease relative to gas production.
A typical commercial operation is described below.
1. 2. 3. 4. Tires delivered to a site are weighed. Tires are introduced to systems whole or else halved, chopped, or shredded. The feedstock is typically dried and preheated, using tire-derived gas. Temperature and residence time in the reactor are two key pyrolysis reactor design criteria. In the gasification stage, tire-derived oil, is condensed and cooled. Light and heavy oil fractions may be handled separate A separator removes any remaining water vapor. The product is filtered. 5. Solid tire-derived char is cooled, typically using a water-cooled stage. The product may be sized and screened to remove fiber. A magnetic separation stage captures magnetic materials remaining in the char. washing the char and further size reducing it produces the carbon black p r o d u c t . 6 Tire-derived gas maintains operating pressure in the system and provides heat to the system. Vented gases pass through a pollution control train, which may include a gas flare. 7. Gas can further treated for power generation. It is passes through venturi scrubber to remove particulate matter from gas and then it is passes through water cooled condenser which can help to bring down the temperature of Tire-derived gas and cracking of tar from it. Further it is passes through various filters containing wood waste and saw dust waste to remove moisture from gas and finally cleaned through fabric filter. Resultant
