The new Impact Catalyst Process is based on the Impact
Crushing proinciple of the Rotoshredder
BHS-Sonthofen has announced that at IFAT ENTSORGA 2010 it will present for the first time the new Impact Catalyst (IC)-Process for the recycling of refrigeration equipment containing CFCs or HCs such as pentane.
The process is based on the successful low-wear, impact-crushing principle of the BHS Rotorshredder, however the method of processing all refrigerants and foaming agents by means of catalytic hydrolysis is totally new. An inertisation of the shredder by means of expensive nitrogen gas is no longer required.
The company claim that its latest innovation offers several major benefits, including:
• Single-stage, continuous size reduction of refrigeration equipment in the BHS Rotorshredder, providing an optimal disaggregation result
• Maximum throughput rates of up to 150 refrigerators per hour
• Extremely low wear
• High availability time
• No explosive atmosphere in the shredder, i.e. size reduc-tion is made without nitrogen inertisation, even when processing
• Pentane fridges
• Ecologically sustainable gas treatment by thermal-catalytic
• Conversion of all refrigerants and foaming agents into saline waste water and CO2 directly within the plant
• Considerably reduced operating expenses as compared to conventional gas treatment (active carbon/ cryocondensation unit). Costs can be lowered even further with an increasing share of pentane fridges
• No expensive liquid nitrogen required
• No further costly loading, transport and final disposal of condensed refrigerants and foaming agents.
The new IC-Process meets all statutory regulations and limits set by EU directives, and the BHS believes offers a very attractive option for higher capacity refrigeration recycling plants due to the significant reduction in operating costs in comparison to conventional methods.
