1 year ago @zasddsgg, syntax errors are Python errors unrelated to BioSTEAM, I encourage you to search online why these occur. Here are a couple of options:
Use a dictionary
a = bst.Stream(
ID='a',
price=0.0516,
units='kg/hr',
Water=500,
H2SO4=600,
**{'sodium chloride': 700}
)Define an alias without a space:
chemicals.set_alias('sodium chloride', 'NaOH')
a = bst.Stream(
ID='a',
price=0.0516,
units='kg/hr',
Water=500,
H2SO4=600,
NaOH=700,
)Thanks,

Hello, I encountered an error when creating a stream: SyntaxError: positional argument follows keyword argument, which should be caused by the sodium chloride I added, but I repeatedly adjusted the position of sodium chloride=700 in the bst.Stream, and the error was still reported. May I trouble you for this error code. Thank you very much. Wish you a good day.
The original code is as follows: import biosteam as bst bst.nbtutorial() bst.main_flowsheet.set_flowsheet('corn stover_ethanol') from biorefineries import cellulosic cs = cellulosic.Biorefinery('corn stover ethanol') chemicals_cs = cs.chemicals NaCl = bst.Chemical('sodium chloride') chemicals = bst.Chemicals([]) chemicals.extend(bst.Chemicals([chemicals_cs.Water, chemicals_cs.H2SO4, chemicals_cs.Glucan, chemicals_cs.Xylan, chemicals_cs.Xylitol, chemicals_cs.Cellobiose, chemicals_cs.CSL, chemicals_cs.DenaturedEnzyme, chemicals_cs.Arabinan, chemicals_cs.Mannan, chemicals_cs.Galactan, chemicals_cs.WWTsludge, chemicals_cs.Cellulase, NaCl])) bst.settings.set_thermo(chemicals) a = bst.Stream( ID='a', price=0.0516,
units='kg/hr', Water=500, H2SO4=600, sodium chloride=700, )
