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.

THERMAL HYGIE­NI­ZA­TION

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.

USABLE ENERGY

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.

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.
