Abstract

Received: 22.03.2013 This paper investigates the possibility to improve the filtering process Accepted: 05.04.2013 of flue gas by separation of suspended nanoparticle using dielectrophoresis. The study focuses on the particles having an average radius of about 50–150 nm, that cannot be filtrated by classical techniques but have a harmful effect Keywords: Flue gas for environment and human health. The size distribution nanoparticles filtration, Nanoparticle collected from the flue gas filters of a hazardous waste incinerator plant were separation, evaluated. Based on obtained experimental data and a proposed Dielectrophoresis, mathematical model, the concentration distribution of nanoparticle Recovery, Purity, suspended in flue gas inside a microfluidic separation device was analyzed Separation efficiency by numerical simulations, using the finite element method. The performances of the device were described in terms of three new specific quantities related to the separation process, namely Recovery, Purity and Separation Efficiency. The simulations could provide the optimal values of control parameters for separation process, and aim to be a useful tool in designing microfluidic devices for separating nanoparticle from combustion gases. 1.
