Caustic price in cornstover biorefinery #31

Closed yalinli2 closed 2 years ago

@yoelcortes , currently the price of caustic is $0.15/kg, however, I think this price is for the pure NaOH, not the 50% solution as in the biorefinery now https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/70b8fc76943985e3128db492465211ef187ce96a/BioSTEAM%202.x.x/biorefineries/cornstover/_process_settings.py#L29

If you look at stream 632 at PDF page 137 of the Humbird report, the flowrates of both water and inorganics are both 2252, Table 30 on PDF page 73 shows that the caustic flowrate is 2252.

Though in the 2018 report, the NaOH price is about 3X as high

Thanks!

I'll take care of rerunning/updating tests later
