HYSYS is one of the most powerful software tools for simulating chemical engineering processes, particularly in petrochemical and refinery industries. This software has the capability to perform both static and dynamic simulations, although it has some weaknesses in dynamic simulation.
HYSYS was originally a standalone software, but recently, the Aspen company acquired it, changing its name from HYSYS to Aspen HYSYS.
Now, let’s briefly introduce the modules of Aspen HYSYS:
In this section, all the substances involved in the process are first entered into the software. Then, an appropriate equation of state or thermodynamic model for liquid substances must be selected for simulation. This module is essentially the starting point of the process and is used in almost 90% of simulations.
It is important to note that if any reactions occur during the process, they must be defined in this section of the software.
This is the core section of the software, where the actual simulation is performed. The main functionality of HYSYS revolves around this module, with other modules supporting it.
Besides process simulation, useful data can also be extracted here, such as Txy diagrams, bubble and dew point determination, and some mechanical simulations like reactor volume estimation.
A process that is not safe will not be efficient. Generally, the processes we simulate during training with this software are pre-tested and safe. However, this module provides tools to conduct process safety analyses to some extent.
This section of the software is used for energy analysis, evaluating factors that contribute to optimizing energy consumption. For example, it calculates the CCF (Capital Cost Factor) and provides an approximate value for it.
