ARENA specializes in ON SITE inertization systems for organic and high calorific waste streams and sludge (medical waste, hazardous waste, …) per the latest standards, and using the latest ecological technologies.
Our ‘Ghibli’ reactor process and gas treatment systems are ‘mild’: using the powerful low temperature suspended silica reactor, with simple and completely dry flue gas treatment with – as needed - particle separation, acid gas neutralisation, NOx reduction and catalytic dioxin conversion. We can offer :

- Turn key systems for on site industrial use as well as maintenance & operation service.

- Build, own and operate projects (BOO) for specific organic hazardous waste streams with local or strategic partners.

Companies producing organic waste or sludge experience increasing costs for destruction or removal of their waste streams. External as well as on-site solutions become more specialized and professionalized.

“GHIBLI suspended silica Reducer Systems” (fluidised bed principle) offer simplicity, affordability, reliability, maximum mass and volume reduction and highest ‘burn-out’ rate.

• Thermal capacity: from ~ 0.1 to over 5 MWth
• Oil Refineries – Food and Petrochemical Industry
• Waste Water Sludge (municipal and industrial)
• Medical Waste.

GHIBLI ‘Suspende Silica’ Waste Reducer Systems

The heart of the GHIBLI Waste Reducer Systems is a medium temperature ‘Suspended Silica’ reactor.

 This reactor contains calibrated silica which is brought in a liquid-like state (suspended particles : fluidized bed) by the injection of air and gas.

Before waste can be introduced, the reactor is heated up to a homogeneous stand by temperature of approx. 500 °C. In this condition, the suspended silica becomes a very powerful reactor, in which a fast and complex physicochemical process will evaporate and strongly oxidize any organic waste in a fully controlled environment (fluidized bed). The organic waste disintegrates easily and submerges in the bubbling reactor as if it were a boiling liquid to be further oxidized and broken down.

Ignited by a permanent pilot burner, the well known “flame screen” is a unique feature characterizing this process. Beside being a simple and reliable means for heating, the flame screen is also used as a primary “safety screen” igniting all organics containing gases as soon as they erupt from the bubbling reactor surface.
Past the flame screen, the gases are routed to an integrated afterburner designed for a temperature and a residence time in accordance with the regulatory requirements.
