CySim - Adsorption model (UK3.5)

Adsorption Process Modelling and Optimisation

The Adsorption group has developed tools for the dynamic simulation and optimisation of adsorption systems for separation processes.

T he adsorption simulator CySim (https://www.carboncapture.eng.ed.ac.uk/lab/cysim) contains different mass and heat transfer models and allows the simulation of multi-column adsorption cycles; thus, it is applicable to a wide range of adsorbents and process conditions. The simulator has been linked to multi-objective optimisation tools for the design of efficient cycle configurations and for the parameter estimation from adsorption experiments. Furthermore, the adsorption simulator can be integrated with complete flow sheet simulations, e.g. coal fired power station, using Unisim Design, the Honeywell process simulator.

  • Validated adsorption simulator

  • Experience in simulating pressure and temperature swing cycles for several different gas separations

  • Optimisation of adsorption processes with respect to purity, recovery, energy consumption and productivity

  • Can be run with flow sheet simulations for the calculation of complete processes

  • Integration with molecular simulation for the calculation of adsorbent properties
