Cyclic separation processes are more important than ever to the chemical process industries. Gas-phase processes such as PSA, VSA and TSA enable air separation, hydrogen purification, CO2 capture and many other applications. Liquid-phase processes such as SMB and liquid chromatography create high value-added products.

The importance of cyclic separation processes creates a strong incentive for optimisation. However, these processes come with many challenges that have historically limited the ability to model and optimise them. Adsorption beds have spatially varying properties with both axial and radial variations. Flow reversals and complex operating procedures make cyclic separations inherently dynamic. Optimised equipment design and operating procedures are typically only meaningful at cyclic steady state. All of these challenges can now be addressed with advanced modelling.

This webinar will demonstrate high-fidelity modelling of cyclic separation processes using the gPROMS platform. The presentation will include application examples that show how modelling can help engineers understand system behaviour, reduce experiments, evaluate alternative processes and optimise the system.

What this webinar covers

  • Adsorption technology: adsorbent properties and types of industrial systems
  • Trends and challenges in cyclic separation process design
