Aspen Adsorption
A comprehensive flowsheet simulator for the optimal design, simulation, optimization, and analysis of industrial gas and liquid adsorption processes
Aspen Adsorption enables process simulation and optimization for a wide range of industrial gas and liquid adsorption processes, including reactive adsorption, ion exchange, and cyclic processes such as pressure-swing, temperature-swing, and vacuum-swing adsorption. It is used to select optimal adsorbents, design better adsorption cycles, and improve general plant operations. Aspen Adsorption is a core element of AspenTech’s aspenONE® Process Engineering applications.
Features
- Rigorous Rate-Based Adsorbent Bed Model
- Various geometries including axial column, horizontal beds, and radial beds
- Options to include axial dispersion in the material balance
- Wide range of kinetic models including lumped resistance, micro/macro-pore, and general rate model
- Wide range of standard equilibrium/isotherm models that allow for either pure component or multi-component/competitive behavior
- Highly configurable energy balance to account for non-isothermal behavior, conduction, heat loss, and wall effects
- Unique Cyclic Steady-State Modeling Paradigm allows use of steady-state estimation and optimization techniques for rapid design and optimization of cycles
- Cycle Management
- User can define any number of independently operated cycles, each containing any number of process steps (e.g., production, purge, equalization, and repressurization)
- Process steps can be controlled by timer or by monitored events
- Steps or ramped changes can be imposed on manipulated variables
- Parameter Estimation tools that allow engineers to fit the models against various types of experimental and plant data
- Rigorous Physical Properties through integration with Aspen Properties; it includes extensive databases of pure component and phase equilibrium data for a wide range of components
- Compatible with Aspen Plus Dynamics®, enabling the simulation of equipment upstream and downstream of the adsorption section
