What is HYSYS simulation?
Aspen HYSYS (or simply HYSYS) is a chemical process simulator used to mathematically model chemical processes, from unit operations to full chemical plants and refineries. HYSYS is used extensively in industry and academia for steady-state and dynamic simulation, process design, performance modelling, and optimization.
What is UniSim used for?
UniSim Design Suite is an intuitive and interactive process modeling software that enables engineers to create steady-state and dynamic models for plant design, performance monitoring, troubleshooting and operational improvement.
What is the difference between HYSYS and UniSim?
HYSYS & UNISIM have almost identical capabilities. HYSYS is older whereas UNISIM is comparatively new. HYSYS being older is used by many companies active in the engineering and design related to oil & gas.
Who uses Aspen Hysys?
Aspen HYSYS is the energy industry’s leading process simulation software that’s used by top oil and gas producers, refineries and engineering companies for process optimization in design and operations.
What is a simulation process?
Process simulation is a model-based representation of chemical, physical, biological, and other technical processes and unit operations in software. The goal of a process simulation is to find optimal conditions for a process. This is essentially an optimization problem which has to be solved in an iterative process.
Which of the following is chemical processing simulation software?
List of chemical process simulators
| Software | Developer | Applications |
|---|---|---|
| Aspen HYSYS | Aspen Technology | Process simulation and optimization |
| Aspen Plus | Aspen Technology | Process simulation and optimization |
| ASSETT | Kongsberg Digital | Dynamic process simulation |
| BatchColumn | ProSim | Simulation and Optimization of batch distillation columns |
What is the difference between Aspen Plus and Hysys?
Essentially the difference is that HYSYS is flow based while Plus is process focused. Thus Aspen Plus is quite good at simulating non-ideal properties, systems with electrolytes, solids, azeotropes, and chemical reactions. While Hysys is optimized for upstream oil & gas, gas processing, and refining applications.
What are the disadvantages of simulation?
Disadvantages of modelling and simulation
- Mistakes may be made in the programming or rules of the simulation or model.
- The cost of a simulation model can be high.
- The cost of running several different simulations may be high.
- Time may be needed to make sense of the results.
