Seeking advice from experts in Aspen for petrochemical engineering design!
Thread Content
I’ve only been learning *Aspen for a short time; I also worked on two examples following the guidelines. There’s still one question that hasn’t been clarified to this day: what can Apsen Plus do for us? From studying chemical engineering principles, we know that there are design calculations and operational calculations for a unit operation. Can the same be achieved in Apsn Plus? How are parametric settings implemented for design-oriented and operational computing? A set of petrochemical units is available; can I use Aspen Plus to identify reasons such as low yields? Has a simulation analysis identified its influencing factors? Thank you so much!
What can Apsen Plus do for us? When I first started learning, I was in the same situation as you, the original poster???? But later, after using the PDP (process design package) from EG across the entire plant, I realized how powerful this software really is, as the results matched the parameters used in actual operations. So when you encounter a bottleneck, you just need to enter the relevant values and you’ll know whether a heat exchanger is insufficient, the purity level is not adequate, or the cooling water system needs to be upgraded, etc.... As for troubleshooting process issues, that might be more difficult to achieve, after all, abnormalities occur during normal operations
Aspen can certainly meet the requirements mentioned by the original poster, enabling design and calculation. I think when Aspen is used in factories, as you said, for an existing setup, it’s possible to input the relevant operational data from regular production into the software for calculations, and then compare the results obtained with those from actual production. Since Aspen yields the most optimal results under the conditions you have set, comparison can be used to determine how far your actual production performance and capabilities fall short of the ideal state. It allows for an analysis of which aspects and operational parameters have not been optimized, so that production improvements can be made to achieve your goals.
Original poster: Software is just a tool; what’s important is your understanding of the manufacturing process! It’s like a camera – professionals can use it to take beautiful photos, while ordinary people using the same camera can only take some casual pictures.
Thank you all for the active discussions. My goal at this stage is to simulate the on-site process in our workshop using Aspen, and based on the performance parameters of the existing equipment as well as those of the catalysts, determine the optimal operating conditions. It would be ideal to also analyze the impact of factors such as sulfur and water content on the catalysts. . .
