Aspen Adsorption and Aspen Chromatography

Optimize cyclic separation processes and maximize production by identifying improvement scenarios and reducing plant trials using proven, high-fidelity models.

Advanced Modeling for Cyclic Separation Processes

All Cyclic Separation Processes

Address pressure-swing adsorption (PSA), temperature-swing adsorption (TSA) and simulated moving bed (SMB) variants such as Intermittent SMB, PowerFeed, ModiCon, and Thermal Gradient.

Various Geometry Options Available

Choose axial column, horizontal beds and radial beds. Include axial dispersion and a wide range of kinetic models such as lumped resistance, micro/macro-pore and general rate.

Flexible, Customizable Solutions

Apply rigorous dynamic modeling or cyclic steady-state approximations to rapidly design  cyclic separation systems. Apply built-in or custom isothermic equations.

Vast Physical Property Database

Rely on a database with 37,000 components, 127 property packages and 5M+ data points and interaction parameters. Employ state-of-the-art activity coefficient models and equations of state.
