Methodology for the Development of Additively Manufactured Packings in Thermal Separation Technology
A methodical procedure for the development of additively manufactured innovative packing structures in laboratory scale is described. Since structural development is an evolutionary process, the focus of this publication is on the methodology of development strategies. Therefore, packing structures based on crystal lattices with flexible dimensioning are created with the visual basic for applications (VBA) tool in Autodesk Inventor (R). For the characterization, computational fluid dynamics (CFD) simulations are applied to examine the dry specific pressure drop and the liquid distribution. Calculations of packing-characteristic values with parameter studies and the above-mentioned CFD simulations reveal indications of the efficiency of these packings. Selective laser sintering using polyamide 12 (PA 12) as material was applied for additive manufacturing of the packing and the column shell.
