I have a few questions regarding distillation column design
Thread Content
:Shut up: I have a few questions regarding the design of distillation columns (using KG-towers or Cup-towers for design and verification). The first question is: after obtaining the basic data on the tray performance using HYSYS or Aspen, which tray’s property data should be used when selecting trays or designing the packing section? Is it necessary to use the data from all the trays for calculations before selecting the tower with the largest diameter? Should we just use the gas-phase load (or liquid-phase load?) ) Should the calculations be based on the data from the largest tray? Secondly, the theoretical number of stages per meter for the regular packing in the Cup-tower is 0.9, and this value cannot be changed. Why is this? Or is it actually the case that the plate equivalent heights of such regularly packed fillers are more or less the same?
The moderator has not used this software. :lol
The plate height varies depending on the type of filler; what matters most is the spotting rate, whether foaming occurs, as well as the spray density, F factor, and pressure drop – all of these need to be taken into consideration
