Multi-component distillation calculation problems in PRO
Thread Content
In vapor-liquid equilibrium calculations, pro2 is often applied to multicomponent systems. However, it seems that there is no yet very accurate algorithm for multi-component distillation calculations. I wonder what calculation method is used for multi-component calculations in Pro2? To be honest, the distillation calculations learned in school mainly focus on binary systems; I don’t have a very thorough understanding of multi-component calculations. Also, what is the role of three-component vapor-liquid equilibrium data in practical applications? Looking forward to a reply from experts.
Let LK and HK be the key components; the calculation method is similar to that of a binary system, but it is much more complex. The poster can check the software manual or books
Is it calculated using key components? You mean the shortcut model, right? But how is the precise calculation carried out? Is it done board by board? If so, how are the multi-component equilibrium data obtained? Are there any relevant materials I can take a look at?
