I have questions regarding the adjacent tower.
Thread Content
The stabilizer tower in the absorption and stabilization section of the company’s catalytic cracking unit uses a side tower; I built a model using Aspen Plus, but encountered problems during the tuning process. The liquid phase distribution in the adjacent tower can be controlled via control valves, while the gas phase distribution should be determined based on the pressures in the pre-distillation section and the side-stream outlet section. In that case, given a certain liquid-phase distribution ratio, how can one determine the gas-phase distribution ratio? Is it necessary to analyze the hydraulics of the two parts? I’m not sure if my approach is correct; I’d like to ask everyone for their advice. @*EJIAHUA
By the gas-phase distribution ratio you mention, do you mean the proportion of vapor at the bottom of the partition that distributes to both sides of the partition? If so, I think a hydraulic analysis is necessary
Thank you for the reply. That’s exactly what I mean. I also think a hydraulic analysis is needed. In current models, the vapor-phase distribution ratios are all manually entered; when hydraulic analysis is required, figuring out how to construct the model becomes a challenge.
