Comparison of four chemical engineering simulation software, chemcad hysys proi aspen

Thread Content

1. It is generally believed that PROII is more accurate in the oil refining industry because there is a lot of empirical data in the database； ASPEN performs better in the chemical industry. Someone compared: PROII is the empirical school, and ASPEN is the academic school. 2. learn * aspen plus essentials (1), chemical engineering principles ； Discuss unit operations (2) and thermodynamic methods of chemical processes ； Explain the calculation method of physical properties ； (3), Chemical system engineering ； Describes how to model chemical systems, analysis, and solutions. If you can simply master it, 1 and 2 are enough. If you want to go further, you need to look at 3. It is also important to have an experienced teacher to guide you. 3. HYSYS is mainly used in oil refining. Dynamic simulation is its strength. ASPEN is intelligent, used for process simulation in the chemical industry, relatively large or long processes, and the database is relatively complete and open. It and HYSYS are now one company. PRO/II can be used for equipment accounting, short process, or distillation accounting. Chemcad is relatively poor and can be downloaded from anywhere on the Internet. For school use only. 4. I think aspen plus’s calculations are the most accurate, and its database construction is also the most complete. But I'm not comfortable with its operation. Because it considers so many aspects, I find it difficult to learn. The interface operation of chemcad feels very simple and easy to use. But the database is not too big. The version 5.0 I use only has physical property data for 2000 commonly used substances. The PRO/II falls in the middle on both counts. 5. From the perspective of easy convergence, chemcad>hysys>proii. From the perspective of being close to industrial reality, proii>hysys>chemcad
