Filtrazione catalitica nell’industria

del cemento

In sintesi, alcune industrie hanno già adottato completamente la tecnologia di filtrazione ceramica come mezzo
per soddisfare gli attuali requisiti di controllo delle emissioni, consentendo inoltre ai clienti di aggiornare i loro
sistemi per soddisfare i requisiti futuri con uno sforzo e un costo ridotti. In particolare, la filtrazione ceramica
consente di ridurre il PM, gli Nox e gli inquinanti pericolosi a valori estremamente bassi in un’unica fase.
L’industria del cemento è ancora all’inizio nell’abbracciare la tecnologia di filtrazione ceramica come uno
strumento prezioso per bilanciare i costi in modo CO -neutro e raggiungere il futuro livello di controllo delle

emissioni.
