ABSTRACT
The need to capture microparticles from gas streams occurs during cleaning of flue gases from industrial installations, the exhaust gases of internal combustion engines, etc. The need to capture is dictated not only by environmental concerns. Often the captured particulate phase is a valuable product. For example, the finest fraction of cement in cement plants is released into the atmosphere, together with the combustion products of fuel used for kilns, while the high content of this fraction in the cement improves its quality. In the production of kaolin by anhydrous technology there is the same situation – the most delicate and most valuable part of the fraction goes away along with the flue gases. Addressing these and similar problems requires the development of effective ways to capture microparticles. There is a huge number of ways but they do not always satisfy the needs of production. At submicron size of the captured particles only electrical and fabric filters are effective.
