Claims (3)
1. Förfarande för rening av upphettade rökgaser genom matning av ett torrt finfördelat absorptionsmedium som innehäller ätminstone en jord- 5 aikaiimetall samt genom att efter detta avlägsna dammet frän rökgasen, kännetecknat därav, att ett absorptionsmedium i hydratform mätäs tili en rökgasdraganordning som efterkopplats tili upphetningsut-rymmet vid en temperatur där dehydrering undvikes och efter matningen av absorptionsmediet och utan föravlägsnande av damm renas ätminstone 10 en delström av rökgasen frän damm först efter en pä förhand bestämd efterreaktionstid och den andra delströmmen omedelbart.
2. Förfarande enligt patentkrav 1, kännetecknat därav, att delströmmen är flerfaldigt avlänkad. 15
3. Förfarande enligt patentkrav 1 eller 2, kännetecknat därav, att bäde den efterreagerande och den icke-efterreagerande delströmmen renas gemensamt frin damm. 20
