PROCEDE DE RECYCLAGE ET DE DEPOLLUTION D'UN GAZ CHAUD, HUMIDE ET CHARGE EN COMPOSES ORGANIQUES VOLATILES, REJETE PAR UN DISPOSITIF DE TRAITEMENT DE MATIERE PREMIERE, ET INSTALLATION METTANT EN ŒUVRE LEDIT PROCEDE

摘要

The method involves recovering hot, wet and charged gases of volatile organic compounds rejected by a raw material processing device i.e. dynamic fluidized bed (1), including a cleaned, hot and dry gas input (3) in a closed loop. The gases are preheated. The gases are cooled under conditions allowing to condense the organic compounds and water contained in the gases and to drain the gas by separation of the gas from condensates. Cleaned and dry gas is obtained and heated. The cleaned, hot and dry gas is reintroduced in the device. An independent claim is also included for an installation for processing volatile organic compounds rejected by a raw material processing device.
