Separation Design with Shortcut Methods
Designing separation sequences is important to achieve efficient processes. The Shortcut Toolbox and the CAPE-OPEN based Shortcut Unit effectively support you in this task.
Simplify Assessment of Separation Steps
In order to gain qualitative insight into a separation, the tools help you to
- determine azeotropes,
- find miscibility gaps,
- draw residue curve diagrams, and
- compute mass balances.
These steps are easily applied to mixtures with an arbitrary number of components. The analysis is based on non-ideal property models using existing property data.
Reduce Energy Cost
Based on the rectification body method (RBM) developed at Process Systems Engineering (LPT) at RWTH Aachen University, you can
- easily determine the feasibility of separation steps,
- calculate the minimum energy demand, and
- quickly screen separation alternatives for energy efficient candidates.
Minimize Entrainer Demand
An extension to the distillation shortcut permits the computation of minimum entrainer demand in addition to energy demand for homogeneous extractive distillation.
Shortcut Unit Model
Plug our CAPE-OPEN compliant shortcut into your flowsheeting simulator:
- quickly analyse separation sequences,
- reuse existing thermodynamics, and
- include the shortcut within recycles.
Ongoing Developments
Current developments tackle
- flowsheet optimization,
- initialization of MINLP optimization problems, and
- heterogeneous distillation
