Consultation about OleinCrystallizer #95

Open zasddsgg opened 7 months ago

zasddsgg commented 7 months ago

Hello, could I consult you some questions about OleinCrystallizer.

a) In https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/cane/systems/biodiesel_actag.py#L41-L45 and https://biosteam.readthedocs.io/en/latest/API/biorefineries/cane/units.html#:~:text=%5Bsource%5D-,Separations,PL%27)%2C%20melt_IDs%3D(%27AcTAG%27%2C)%2C%20order%3DNone),-%5Bsource%5D, there is the OleinCrystallizer unit. But when I looked through O1 = cane.Biorefinery('O1'), O1.oilcane_sys.units, I didn't see the OleinCrystallizer unit, Can I consult you how to view a system with OleinCrystallizer unit?

b) In https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/cane/systems/sugar.py#L141, the BatchCrystallizer is used. Could I consult you what is the difference between BatchCrystallizer and OleinCrystallizer? I study the source code of them in https://biosteam.readthedocs.io/en/latest/_modules/biorefineries/cane/units.html#OleinCrystallizer and https://github.com/BioSTEAMDevelopmentGroup/biosteam/blob/master/biosteam/units/_batch_crystallizer.py, It seems that the calculation method of Hnet is different, the Hnet of OleinCrystallizer is the difference between solid substance enthalpy in the outlet and inlet. Why is Hnet calculated differently?

c) If there is liquid state riboflavin and other impurities in the feed, I want to cool and crystallize the riboflavin to recover the riboflavin, and other impurities may also be precipitated during this process (I am not quite sure). Could I consult you which unit (BatchCrystallizer and OleinCrystallizer) shall I use?

d) In the source code of OleinCrystallizer (https://biosteam.readthedocs.io/en/latest/_modules/biorefineries/cane/units.html#OleinCrystallizer), could I consult you what is the meaning of solid_purity and melt_purity?

Thanks for your help. Wish you a good day.
