An Open-Source IDAES Framework for Simulating Inductively Heated Adsorption Processes

Magnetic Inductive Swing Adsorption (MISA) is a carbon dioxide capture process similar to Temperature Swing Adsorption that uses direct electromagnetic heating instead of classic heating systems for the regeneration step of the process. However, the lack of validated dynamic models hinders process optimization. This work introduces an open-source MISA model in the IDAES framework, incorporating Specific Absorption Rate (SAR) physics (SAR ? B²) to capture electromagnetic heating. Binary Sips isotherm parameters for Fe3O4@HKUST-1 were fitted to experimental data, achieving high statistical agreement (R2 > 0.996, RMSE < 0.022 mol/kg). Comprehensive validation was performed against adsorption isotherms, dynamic breakthrough curves, and desorption profiles. The model predicts breakthrough time with only 9% error and saturation time with 6% error. Crucially, the coupled thermal transport and SAR heating model capture temperature evolution during desorption within 5% error across all field strengths. Although the use of Linear Driving Force kinetics introduces minor systematic overprediction, the model successfully bridges the gap between laboratory feasibility and industrial design. This validated tool enables the first systematic investigation of cycle configurations, providing a platform for techno-economic comparisons and scale-up of energy-efficient magnetic carbon capture.
