AbstractFiltration of liquid aerosol (mist) is one of the most important challenges in many branches of chemical industry. The main goal of this process is to separate liquid particles from exhaust gas and gas purification to meet the requirements of environmental and human protection. One of the possible ways of modification is deposition of aerogels on filtration fibres. In this study aerogels based on methyltrimethoxysilane (MTMS), which exhibit superhydrophobic and superoleophilic properties were used. Such material has very good sorptive properties for oils, mainly thanks to its high porosity. Modified filters were imagined by SEM. Also the efficiency of oil mist separation has been investigated. The aerosol liquid particles with a wide range of diameters – from nanoto micro-sized - were applied in the testing procedure. Though the pressure drop during the filtration on modified filters has been higher, the presented modification seems to be a promising method of improvement of fibrous filters properties.
