Abstract:The objective of this study is to elaborate the use of nano filters for controlling the pollution of the industries coming out of the chimneys. The nano filters allow small gaseous molecules to pass trough them. The nano filters are the kind of filters that have the pores of the size 3-20nm. The main component that is considered most important for the removal from the industrial pollution is NOx, i.e., NO2 or NO. The SCR (Selective Catalytic Reduction) technique can be used for the control of NOx emission from the chimneys of the industries. In SCR technology the mostly used catalyst is Aqueous Urea {in the form of solid particulate form}.The nano filter and the absorber must be used together to control the emission of pollution from industries.
