CARBONISATION – EFFICIENT AND PROFITABLE
Carbonisation – 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. Efficient, environmentally friendly and without harmful by-products: You can rely on us – we are the world market leader.
In principle, the carbonisation in the PYREG process is as follows (similar to pyrolysis). The dried feed material (at least 65% dry matter content) is fed through the 500-700 °C hot PYREG reactors. There, the material is not burned, but first degassed gently and then carbonised by the addition of specific air. The material is thus completely hygienised.
NO PROBLEMATIC SUBSTANCES
Since the combustible gases produced in the reactors are completely combusted in a downstream combustion chamber in the FLOX process (flameless oxidation) at around 1,000 °C, the process produces little thermal NOx. This also means that there are no problem substances such as oils or tars, since the carbonisation gas is not cooled but thermally oxidized in the afterburner chamber.
In an optional downstream exhaust gas purification stage, the acidic harmful gases are removed from the exhaust gas in an alkaline flue gas scrubber and volatile sewage sludge components such as mercury are adsorbed onto an activated carbon filter.
Carbonisation is also autothermal, which means that only some external starting energy is required. Subsequently, only the energy contained in the sewage sludge is used to maintain the process. In addition, up to 150 kWth or 600 kWth of excess heat energy can be used for sludge drying.
The PYREG System Movie
WHY A PYREG SYSTEM PAYS OFF
A PYREG system is extremely cost-effective and guarantees maximum flexibility. Only a small amount of initial energy is required to operate the compact system. Once the process has started, the PYREG system produces its own operating heat. In addition, further energy contingents are available and can be used for drying or other peripheral uses.
Reduction of transport costs (more than 80%) through decentralised recycling.
Reduced space requirements and handling costs.
Reduced administration effort etc.
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.
