Working with our Partners, ETIA/VOW , we are able to take Rubber Crumb and convert into Carbon Black and Oil

The process is a continuous thermochemical conversion of tyre waste streams, that allows continuous pyrolysis and gasification processes to produce carbon black.

Pyrolysis Mode 

•    Mode: Range of Temperature: 450 < T < 650°C 

Gasification Mode 

•    Mode: Range of Temperature: 600 < T < 850°C 

 How the unit works 

1.    Dry crumb is introduced in a hopper with regular and controlled flow. Particle size and moisture will affect the yield of biochar, oil and gas. 

2.    A high temperature rotary valve or dosing screw introduces the dry crumb into the pyrolyzing chamber. This chamber is based on SPIRAJOULE® technology, an exclusive and patented electrical heating screw conveyor. This process allows perfect monitoring and control of dwell time and temperature during the process. Temperature can be adjusted precisely up to 800°C depending on specifications required. Dwell time of the solid phase can be adjusted from 5 to 30 min. Adjustment of operating conditions defines the ratio of TP oil, biochar and gas produced with the process. 

3.    Gas generated by the process exits from the top side of the SPJ pyrolyzing chamber and goes directly to a condensing and/or gas cleaning system by circulation of chilled water. Bio oil and water are the liquid phase coming out from the condenser. The w/w ratio of biomass converted into bio oil depends on biomass composition and operating conditions but generally in the range from 20% to 60% 

4.    Solid phase coming out from SPJ pyrolyzing chamber is quickly cooled down into a flash cooler based on a double jacketed auger cooling screw mounted with water spraying device. Biochar is then cooled down to a temperature which should not exceed 50°C. The w/w ratio of waste converted into biochar depends in biomass composition and operating conditions 

5.    The non-condensable gas (NCG) coming out from condenser have energetic value and may contain some organic molecules. This gas can be used as fuel to be burned in a combustion chamber or can be treated and use in a turbine or gas Engine to produce electricity and heat (CHP).
