Abstract

This study presents CADET-Julia, an implementation of the Discontinuous Galerkin spectral element method (DGSEM) in Julia, applied to the Lumped Rate Model (LRM) and multi-component Langmuir isotherm for binary separation in both batch and simulated moving bed (SMB) operation. A comparative analysis was made of CADET-FV and CADET-DG, C++ implementations of finite volume and DGSEM found in CADET, respectively. For stiff systems operated in batch mode, CADET-FV, CADET-Julia and CADET-DG showed similar performance, however, for less stiff systems, CADET-Julia and CADET-DG were superior. For stiff systems in SMB operation, CADET-Julia was significantly faster than CADET-FV. CADET-DG could not be benchmarked at the current time.
