I have a question regarding the atmospheric and vacuum distillation of crude oil

I have built a crude oil atmospheric distillation column with side-stream outputs, aiming to obtain products such as naphtha, kerosene, and diesel. There is no side-stream stripping tower; instead, sampling is done directly from the tray levels. By adjusting the tray levels and the initial amounts of material fed into the column, it is possible to achieve the desired distribution of the products. During this process, I found that the material drawn off via the side line was not the entire liquid phase on that tray, but only a portion of it. Is this reasonable? Is it the same in practice as well? I know this is related to the reflux ratio; how is the amount of side stream controlled in engineering? Thank you, senior
Reply to 1# Daney: What does the poster mean by “not all of the liquid phase is drawn off through the side line, but only a portion of it”? Please explain! Additionally, I am also working on atmospheric and vacuum distillation simulations, using Aspen Plus and HYSYS; I hope to discuss this with you!
