Membrane condenser for particulate abatement from waste-gaseous streams

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH, HF, SO) removal and control from waste gaseous streams was also proved. In the present work, the application of membrane condenser for water recovery as well as microparticles removal from gaseous streams are presented. Experimental tests showed that microparticles did not affect membrane condenser performance, neither in terms of water recovery nor in term of fouling. Moreover, the carried-out tests revealed also that the complete retention of particles can be achieved only through the proper choice of the membrane, with pore size lower than particles diameter.
