Experimental Determination of the Permeability of Non-Porous Planar Structures during Operation of Equipment in Own Industrial Unit

Abstract:

The permeability is a physical property related to porous structures. It is a physical quantity that quantifies the resistance that a permeable matrix has to the flow of a particular fluid. Knowledge of the permeability of a filter media is important for the design, optimization and operation of various equipment, such as fabric filters, sedimentary, filtering hydrocyclones and others. There is the routine that the experimental determination of permeability of a filter medium is not made during the operation of industrial equipment, because they require a specific instrumentation or because it not presents a flat filtration. Therefore the experimental determination of permeability occurs out the industrial, in testing of laboratory by flat filtration. The two different times (industrial and laboratory) increase operation costs for the user by requiring uninstalling or fragmentation of the equipment to take it the laboratory. This work aimed to present a methodology (experiments combined with CFD techniques) in which it is possible to determine the permeability of a filter media (non-flat geometry) in their own manufacturing plant. According to the main results achieved, the proposed methodology was satisfactory, eliminating the need for characterization of filter media in the laboratory.
