There is an error in the Aspen hydraulic calculation; can I ignore it and proceed with the simulation?
Thread Content
I used the radfrac module to simulate the absorption of CO2 by alcoholamine solutions; since the initial flow data and tower structure parameters were taken from reference literature, making modifications was rather limited. The process simulation is working fine at the moment; the issue lies in the hydraulic operation diagram. Since I’m not interested in studying these hydraulic calculations either, I was wondering if it’s possible to ignore the hydraulic aspects and proceed with the simulation anyway?
In Aspen, hydraulic calculations are an important step used to determine parameters such as the flow pattern, flow velocity, and pressure drop of the liquid and gas phases within the column. If errors occur in the hydraulic calculations, it may affect the accuracy and reliability of subsequent operations. Therefore, it is recommended that you recheck the input parameters in the hydraulic diagram and attempt to resolve the error to ensure the accuracy of the simulation. If you are not very familiar with the principles and methods of hydraulic calculations, you can first learn the relevant knowledge or seek help from professionals. If you are absolutely certain that the hydraulic calculations are unrelated to your research question, you can also try to ignore the error and proceed with the simulation. However, this approach may introduce some errors, and you assume the risk accordingly. .
Okay, thank you very much. I wasn’t originally aiming to design a tower; I just used data from existing studies to simulate a tower that is as close as possible to the experimental data. My future research will focus on things like process optimization and economic analysis, so I plan to ignore the hydraulic aspects if it’s not necessary.
