Used tyres / Waste Plastics / Segregated to sizes suitable  Plastics  are baled to sizes suitable to the feeder hopper and fed to the reactor through the Hydraulic air lock tight feeder to the reactor

​

• The scrap / waste tires  or plastics are reduced to size and fed to the reactor through the hydraulic air lock feeder.

  • In case of tires and auto parts one  25mm to 40mm lumps

  • In case of waste plastics such as PP/PE/HDPE/LDPE depending on physical structure i.e. solid or films 40mm lumps In case of lumps 25mm to 40mm lumps  and in case of films and scarp pp bags  in 24” x 36” x 24”   sized compressed  bales.

  •  Mixed waste plastics previously  tested for minimum calorific value of 8000 KCALS/KG and max. 5% ash content is compressed into bales of size 24” x 36” x 24”.

• A hot air generator fired by Diesel /Furnace Oil /Light Diesel Oil /recycled Pyro gases heats the contents of the reactor to a temperature of 475 o C in the absence of air.

• The addition of catalyst modifies the molecular structure of the rubber / plastic during the pyrolysis process as a result fuel oil in vapor form is produced along with other gases.
   

• The mixture of gases and vapors are passed through heat exchangers cooled with water to condense the fuel oil vapors into liquid form.
   

• The fuel Oil so produced is further processed and filtered to purify the product and bring it up to commercially acceptable quality parameters.
   

• The residue emanating from the reactor is carbon black . If ash content is less than 5% it can be sold as raw material for upgrading to carbon black suited for tires or for production of activated carbon. However, if Ash content is high due to presense of fillers in the mixed plastic then the carbon could be separated from the residue by the process of electrostatic separation. The high ash residue could also be used as a filler in construction industry.
   

•  Carbon black used by the tire and ink  industry or activated carbon used for water purification .
   

• The combustible gasses stripped off fuel oil vapors  are fed to the Hot air generator burners burners which provide the heat to the reactors for the pyrolysis process thus rendering the whole process self sufficient as far as heat energy is concerned.External source of energy is required only for cold start up.
   

• The coolant water circulated in the heat exchangers is cooled in a cooling tower and recycled in a closed loop.
   

• The finished product fuel oil is pumped to the storage tanks for sale.
   

• In view of the  combustible & explosive nature of the pyro gas and pyro oil all electricals are of flame proof and explosion proof construction.
   

• The plant is adaptable to any raw material as indicated in the chart below. However, Choice of raw material is always based on how commercially  viable the processing is.
