Destruction sans danger pour l'environnement des CFC responsables de la destruction de l'ozone stratosphérique.

Environmentally safe disposal of ozone-depleting CFCs.

Résumé

Waste refrigerants recovered from industry, such as R12, R115, R502 and R22, can be easily converted into the valuable chlorine free products, which may be recycled into the market. A high selectivity to HFC-32 can be combined with a complete CFC-12 conversion by using an additional catalytic purification step. A pilot plant with a capacity of about 1 kilogramme/hour was designed and will be tested for the conversion of waste R12 into HFC-32 within this year. The preliminary process design has shown that the conversion of CFC-12 into the high added value product HFC-32 is both technically and economically feasible. The design can easily be extended to a process for conversion of both HCFC-22 and CFC-115 into HFC-32 and HCFC-125 respectively.
