Design of laboratory cyclone separator for biogas purification

Abstract

This article deals with calculation of a cyclone separator for biogas purification using physical and chemical methods. There is presented a methodology for determination of operating dimensions of the cyclone separator and description of principal features of the cyclone separator model. 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. 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. The developed cyclone separator has been used for the cleaning of biogas in operating conditions at the biogas plant in Kolinany (Slovakia). 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. Removal of these undesirable impurities from the biogas is an important step in the production of a fully valued fuel, biomethane.
