Vector acceleration methods – adsorption process simulations

The REPAIR project is proud to share the news of (Kian Karimi and Matteo Gazzani) sharing their latest open-access paper published in Industrial Engineering & Chemistry Research.

Simulating adsorption processes, which are widely used in air separation, CO2 capture etc., often require significant computational effort. One of the main challenges is reaching cyclic steady state (CSS), the state at which the process performance stabilizes.

Accelerating CSS determination has been an active research area for almost three decades now. We are glad to contribute to this important topic with our latest work, where we explore vector acceleration methods to achieve faster CSS convergence in adsorption process models.

Our findings show that these methods can achieve up to 4× speedups, and they can be incorporated into existing process simulators with relatively minimal effort.

This work was carried out as part of the Repair-eu project, funded by the European Commission through CINEA under the Horizon Europe framework.

Special thanks to Rahul Anantharaman for insightful discussions!
