Process simulation is a process that is used for the development, design, analysis, and optimization of many different types of technical processes. This may include options like biological processes, chemical processes, chemical plants, and power stations to name a few. We are going to take a look at how chemical process simulation is meant to work.
The Main Idea
To start, process simulation is going to be a representation done in a model about chemical processes and unit operations that show up in the software. There need to be some prerequisites in place for this to work, though the two that must show up all the time are the physical and chemical properties of the mathematical models, pure components and mixtures, chemical and physical properties, and the reactions. This will provide enough information to the software to figure out what is happening.
The software in process simulation will help us describe the different processes in a flow diagram, making it easier to see what is happening and what is likely to happen at some point. The software can then solve the mass and energy balance, ensuring that you will find the stable operating point based on the parameters that you are looking for. So basically, we are trying to find a way to optimize the problem that we want to work with.
We will need to rely on a lot of models in this simulation to provide us with a place to make our assumptions and approximations well. We can use real data to help with this, giving us the most accurate options, based on what we know when we set things. When we can use what we already know, it is easier to learn some of the unknowns in the process. The two main types of models that you may make throughout this includes predictive methods to estimate the properties and equations and correlations where you add in the parameters and fit them to your experimental data.
