Water - oil emulsion separations are of importance to petrochemical industries. Water molecules of less than 100µ diameter are present as secondary emulsions. The presence of water reduces the efficiency of the fuel combustion, the water droplets can plug or interfere with performance of small orifices, and the water can dissolve polar compounds from the fuel and form corrosive materials such as sulfuric acid which can damage engine parts. Thus, fuel filtration extends the life of engine. Coalescence filters are efficient and effectual for the removal of secondary emulsions. The surface functionalization of fibers used to make coalescence filters can potentially provide cleaner air, and cleaner fuel with reduced water concentration. The solid surface energy of the fiber is a crucial factor in coalescence phenomena. The aim of this work is to eliminate these water molecules by development of filters made of glass with modified surface energy using coupling agents like silanes. Three coupling agents used in this work are 3-aminopropyltriethoxysilane (APTS), (2-(carboxymethylthio) ethyltrimethylsilane) (CES), and ((heptadecafluoro-1, 1, 2, 2-tetra-hydrodecyl) trichlorosilane) (FTS). The APTS functionalized surface having an intermediate surface energy of 65mJ/m2 was found to be the most effective fiber for water-in-oil coalescence. Functionalized and unfunctionalized fiber filters were also tested for gas-liquid coalescence filtration. The experimental results showed an improvement in the performance of FTS coated glass filters compared to the untreated glass fiber filter. Intermediate wettability is commonly accepted to provide the best coalescing filter performance, but direct experimental evidence is scarce. This work experimentally confirms that intermediate wettability provides the best performance.
