What do the software packages do?

The best chemical process simulation software packages help chemical engineers design, optimize, and troubleshoot chemical processes. They can also be used to train process operators and to assess the impact of changes on process performance.

The most popular chemical process simulation software packages are Aspen HYSYS, CHEMCAD, and Pro/II. These software packages have different strengths and weaknesses, so it is important to choose the right one for your needs.

Aspen HYSYS is a powerful process simulation software package that can handle complex processes. It has a wide range of features, including a user-friendly interface, good documentation, and strong support from the vendor. However, Aspen HYSYS is expensive and can be difficult to learn.

CHEMCAD is another popular process simulation software package. It is less expensive than Aspen HYSYS and has a more intuitive interface. However, CHEMCAD does not have as many features as Aspen HYSYS and its documentation is not as good.

Pro/II is a process simulation software package that is well suited for small-scale processes. It is easy to learn and use, and its documentation is excellent. However, Pro/II does not have as many features as Aspen HYSYS or CHEMCAD.

How do you choose which package is right for you?

There are many different process simulation software packages available on the market, and choosing the right one for your needs can be a difficult task. Here are a few factors to consider when choosing a process simulation software package:

-The size and complexity of your process: Some process simulation software packages are better suited for small, simple processes, while others are designed for more complex processes.

-Your specific needs: Some software packages offer more features than others, so it is important to choose a package that has the features you need.

-Your budget: Process simulation software can vary widely in price, so it is important to find a package that fits within your budget.

What does each package cost and what are the differences in price?

The cost of each package depends on the features and functionality you need. The most basic packages start at around $500, while the most comprehensive packages can cost up to $5000.

The main difference in price is the number of licenses you need. If you only need one license, then you can get away with a less expensive package. However, if you need multiple licenses for a team of engineers, then you’ll need to spend more to get a package that can accommodate multiple users.

Another factor that affects price is the level of support offered. Basic packages usually come with limited support, while more expensive packages include premium support from the software vendor.

Finally, some packages offer additional features such as cloud-based collaboration tools or integrations with other software programs. These add-ons can increase the price of a package, but they may also be worth the investment if they offer valuable functionality for your engineering team.


There are many different chemical process simulation software packages available on the market today. While they all have their own unique features and benefits, we believe that the ten products on our list are the best of the best. If you’re looking for a top-quality simulation package to help you with your work as a chemical engineer, then any one of these would be an excellent choice.
