Aspen EO Modeling Option
Aspen EO Modeling Option is the Equation-Oriented (EO) model
library option for use with Aspen HYSYS. It enables large process
simulation models (including Aspen HYSYS) to be converged rapidly
using the EO solution mode.
Features
Equation-oriented strategy can be very effective for the kinds
of problems such as:
- highly heat-integrated processes
- highly recycled processes
- processes with many design specifications
- process optimization
- process model tuning through data reconciliation and parameter
estimation
Benefits
- Solves the entire flowsheet simultaneously without nested
convergence loops and utilizes analytical first order
derivatives
- EO strategy can solve much larger problems using the same
computational effort
- Solves the simulation of highly heat-integrated or recycled
processes
- Optimization of plant operating conditions to maximize
profit
