Optimizing the feed position for multi-stream feeding in distillation columns using CASE STUDY
Thread Content
For a distillation column simulating multi-feed situations, are the results of optimizing the positions of the two feed plates simultaneously using a CASE STUDY identical to those obtained by optimizing them separately?
I think it’s definitely different. I’ve only simulated optimizing the position of one feed plate; optimizing both at the same time has not been tried yet. I’m not sure if it will work – I think the computational load is too high, so I’m not certain whether it’s feasible
Agree with the person above; it’s likely not feasible, and it may not be reliable either. I think, in such a situation, an optimization should be carried out first to determine the ratio of the light and heavy key components inside the distillation tower, so as to arrange the second stream of material and avoid reverse distillation.
One could try optimizing both feed positions simultaneously using an optimizer first, and then use operating condition analysis to optimize them one by one; this should help reduce the amount of computation required. It’s just my opinion; I’m not sure if it’s feasible, just offering it for discussion.
