ASPEN simulation

It’s normal for there to be differences; in my opinion, experimental data should still be the guiding factor

There will definitely be errors, plus the conditions are different too

As a commercial software, to enter a market abroad it must undergo testing by authoritative industry organizations; only if it meets the required standards can it be approved for use. ASPEN has been widely used abroad, which is why it was adopted in China without going through any testing first. As widely used commercial software, if it differed too much from the actual values, it would have long been discarded as junk and lost its purpose – just like no one would spend hundreds of thousands on a BMW if it couldn’t outperform a bicycle Someone once suggested manually rechecking the ASPEN calculation results to see the differences – isn’t that like taking off one’s pants just to fart? What more is there to need software for? The key to learning professional software lies in the theoretical foundation. Whether it is model software like PDS, stress calculation software like CII, or process calculation software like ASPEN and PRO II, they are all merely tools; it is a person’s competence and knowledge level that determines success. Thinking that you can land a professional job just by playing with a piece of software is nothing but a dream. For example, the results produced by CII software are meaningless; one can achieve the same outcome by training a cleaner to enter the data mechanically. The key lies in knowing how to interpret the reports, identify the root causes of problems and make adjustments, as well as carrying out proper flexible design and pipe support. No manual can teach you this – it all depends on experience and skill. I don’t recommend that beginners who have just started working start using software right away, as it can lead to serious problems. For example, as in the case of the person who posted the question, if they can’t even figure out the root cause of the issues, what’s the point of learning it? The key to ASPEN simulation calculations lies not in the operations themselves, but in a good understanding of chemical engineering principles, thermodynamic knowledge, and numerical calculation techniques. It is necessary to select an appropriate thermodynamic model; choosing the wrong model can lead to significant differences in results. The documentation provided with the ASPEN software explains in detail under what conditions each model should be used. It is essential to first grasp the theoretical aspects before attempting to carry out the calculations. Experience in using ASPEN is also crucial, as computers are ultimately machines, and human judgment is needed in many situations. If data is entered on one side and construction drawings are generated immediately on the other, then what’s the need for people? The boss can just buy a machine and start making money.
