CARBONIZATION – EFFICIENT AND PROFITABLE
Carbonization – the conversion of natural material to biochar, feeding char or activated carbon – is a process that has been known for many centuries. However, only the PYREG process allows the precise control of the parameters, so that carbon products can be produced in various quality grades and nutrients can be recycled gently. In addition, most of the carbon contained in the input material is stored in a stable way and not released into the air as CO2. Efficient, climate friendly and without harmful by-products: You can rely on us – we are the world market leader.
The PYREG process is a continuous method and uses the principle of dried carbonization. For that purpose, the input material (at least 65% dry matter content) is not incinerated, but first degassed at a temperature of 500-700 °C and then, by admission of a well-defined air stream, carbonized. The material passes through the PYREG reactor, hauled by conveyor screws. As this process enables users to precisely adjust treatment parameters like temperature control, carbonization time and admission of primary air, the optimum quality of the final product can be achieved.
NO PROBLEMATIC SUBSTANCES
As the combustible gas generated in the PYREG reactors is completely burned by the FLOX® method (flameless oxidation) at a temperature of 1,000 °C inside a separate combustion chamber, thermal NOx is significantly avoided. The formation of problematic substances like oils or tar is suppressed as well, because the carbonization gas is not cooled, but oxidized in the combustion chamber.
Inside an optional flue gas cleaning system, harmful acid gases are absorbed by means of alkaline flue gas scrubber, whereas volatile components like mercury are retained by charcoal filters.
The carbonization process is self sustaining; after completion of the activation phase no further external energy is required to run the process, as the energy of the sludge is sufficient for the continuance of the thermal treatment. It is even possible to benefit from the excess heat produced; an amount of 150 up to 600 kWth may be used for drying of humid biomass, for heating or power generation.
The PYREG System Movie
WHY A PYREG SYSTEM PAYS OFF
Reduction of transport costs (more than 80%) through decentralised recycling.
Reduced space requirements and handling costs.
Marketing of CO2 emission certificates
In-house instead of external exploitation: Planning security through decoupling from market price developments.
Revenues from the marketing of carbon products.
Marketing of the surplus regenerative energy.
Avoidance of otherwise necessary alternative investments.
Long-term disposal security even with stricter limit values and environmental protection regulations.
