Is it necessary to learn process control system configuration for HYSYS simulation?
It’s not necessary. HYSYS is merely used for process simulation; configuration involves integrating it with actual equipment, which falls under the category of applications.
In some special cases, such as when using HYSYS for OTS projects, it is necessary to learn *DCS system configuration and control.
Yes, if you know nothing about process control, how can you create a good dynamic simulation?
Don’t get hung up on details; you’ve only carried out dynamic simulations. You should know that most of the functions of process simulation software are related to steady-state simulations. Additionally, it’s important to correct the misconception that HYSYS is considered a software whose strength lies in dynamic simulations – this isn’t the case; HYSYS has greater strengths in steady-state simulations for oil and gas processing.
HYSYS is a software that combines dynamic and steady-state analysis. For chemical plants, and especially refineries, dynamic simulation is the main approach. So it is still necessary to understand the control strategy; otherwise, the simulation cannot be carried out properly, the model cannot be built correctly, and it may not even be possible to achieve effective control. For DCS system configuration, it’s sufficient to have a basic understanding; there’s no need to go into too much detail.
The discussion is quite lively. I’d like to add my two cents as well: In most cases in China, HYSYS is used for steady-state simulations, and there’s no need to learn process control; knowing how to perform process flow simulations is sufficient. The part related to connection with DCS systems comes into play only in dynamic simulations, but it’s quite difficult to master* haha
After acquiring Hysys, Honeywell has been using UniSim Design for OT
It mainly depends on what it’s used for In the case of steady-state simulation, there is no need to consider how control is implemented; however, for dynamic simulation, some understanding of control is necessary.
