Thickness and Shape Optimization of Filter Sheet by Non-Linear FEA
Filter Sheets are non standard components and hence the guidelines for design are loose under the ASME and the TEMA code. The usual engineering practice is to extend the ever current design is available with an increased factor of safety. However this results in excessively heavy designs, resulting in increasing costs (e.g. Material, transport, assembly and installation).Hence in such designs there is maximum scope for optimization. Optimization goals are focused on Installing maximum possible filter tubes in a single plate thus increasing the capacity – Shape Optimization and Designing an optimal thickness for filter sheet assembly component for maximum economy – Material optimization. The Project execution phases consist of Analyzing a proposed for both Shape and Material optimization and submission of reports to clients, (In this phase we analyze only 1/6th portion of the assembly) Based on approval and feedback of client, designing the entire assembly and submitting drawings and models for approval) On approval of client proceed with analysis of the entire model created in phase 2. Performing actual hydro tests on the assembly after manufacturing, and evaluating effectiveness of FEA analysis. Preparing Information sheets and guideline processes for future project implementation. The challenges for FEA validation are Performing Shape Optimization and making filter pattern in accordance with manufacturability and ergonomic evaluations. FEA validation should certify a FOS of 5, as required by the guidelines of the Saudi Arabia Oil Code. FEA validation being comparable in case of Hydro Test performance on actual installation of assembly. The outputs of FEA work shall be a shape Optimized Filter Sheet assembly, with maximum productivity and maximum economy. Deformation and Stress Certification for performance in Hydro Test which shall take place at 2.5 times the actual working conditions.
