Consultation about MESHDistillation

[zasddsgg]

Hello, may I ask you some questions about MESHDistillation? Thanks for your help. Wish you a good day.

a) Does the reflux ratio in BioSTEAM’s MESHDistillation refer to the mass ratio or molar ratio?

b) Could I consult you when does MESHDistillation and BinaryDistillation need a full condenser (https://biosteam.readthedocs.io/en/latest/API/units/distillation.html#:~:text=Simulate%20distillation%20column%20with%20a%20full%20condenser%2C%205%20stages%2C%20a%200.673%20reflux%20ratio%2C%202.57%20boilup%20ratio%2C%20and%20feed%20at%20stage%202%3A)?

c) Can neither MESHDistillation nor BinaryDistillation set the mass ratio of distillate (ratio to feed stream of column)?

d) Could I consult you what are the differences between the several Distillation towers in BioSTEAM (https://biosteam.readthedocs.io/en/latest/API/units/distillation.html), especially MESHDistillation and BinaryDistillation?

e) Is the MESHDistillation equivalent to the RadFrac column in Aspen plus? How can the number of stages to be input and the position of stages to be fed be obtained for the MESHDistillation?

f) Could I consult you which distillation tower is usually used to build the process?

g) Is it OK to use BinaryDistillation (instead of MESHDistillation) to build the process?

h) Do boilup and reflux ratios (https://biosteam.readthedocs.io/en/latest/API/units/distillation.html#:~:text=boilup%20(float,at%20the%20condenser.) in MESHDistillation and BinaryDistillation refer to molar ratios or mass ratios?

i) Could I consult you how to set thermo in the MESHDistillation and BinaryDistillation (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/HP/system_sugarcane.py#L485), when to set thermos=ideal_thermo, and when to set thermos=None?
