The effect of cyclone length on separation efficiency and pressure drop has been investigated experimentally and theoretically by varying the length of the cylindrical segment of a cylinder-on-cone cyclone. Hoffmann, AC de Groot, M Peng, W Dries, HWA Kater, J Removal of these undesirable impurities from the biogas is an important step in the production of a fully valued fuel, biomethane.Īdvantages and risks in increasing cyclone separator length The presented method of biogas purification has been used for the removing of hydrogen sulphide, particulate matter and carbon dioxide from the raw biogas at the biogas plant.
The developed cyclone separator has been used for the cleaning of biogas in operating conditions at the biogas plant in Kolinany (Slovakia. The calculations can be used in practice for the design of cyclone separator depending on the flow rate of biogas, size of the biogas plants respectively. Calculations have been performed for the diameter of the cylindrical part of cyclone separator 175 mm and for the biogas volume flow rate 6.9∙10−5 m3∙s−1. There is presented a methodology for determination of operating dimensions of the cyclone separator and description of principal features of the cyclone separator model.

The size of the particles separated from this experiment will be used to further refine our model.
We filled a chamber with Arizona test dust and utilized an acoustic suspension technique to segregate particles finer than a coarse cutoff size and introduce them into the cyclonic separation apparatus where they were further separated via a vortex following our computational model. To test the model, we constructed an experiment to separate a test dust of various sized particles. Using the OpenFoam computational package, we were able to determine the flow parameters of a vortex in a cyclonic separator in order to segregate dust particles to a cutoff size of tens of nanometers. This has led us to believe that cyclonic separation has more applications than the agricultural and industrial. Currently, cyclonic separators are primarily used in agriculture and manufacturing to syphon out contaminates or products from an air supply. The ability to separate particles based on their size has wide ranging applications from the industrial to the medical. Microparticle Separation by Cyclonic Separation
