ProII tower type

There’s an example problem on the forum regarding tower design, which uses Shotcut and precise calculations; I’m not sure if it will be useful to you

By \"distillation,\" the poster means the rigorous calculation method; by \"shotcut,\" he refers to the simplified calculation method. Meanwhile, \"side column\" denotes a tower equipped with side-line stripping, such as the atmospheric and vacuum distillation towers used for crude oil, which have side-line stripping units. Generally, we first use a simplified calculation method (shotcut) based on the separation requirements to determine the minimum number of theoretical plates, the minimum reflux ratio, and the heat loads of the top condenser and reboiler required to achieve the specified separation goals. Then, calculations are performed using the rigorous method based on the results obtained by the simplified method, with the initial values for the rigorous method being the results from the simplified method. The original poster can take a look at the simulation process of some towers.
