Hello

I have tried to run TEA for the preprocessing of a biorefinery using the same code provided in the documentation, however it shows the following error:

I have tried to fix this error, however I am unable to solve. The code is given as follows:

Note: This code would not be able to run it because different unit operations are used other than available in the repository. I am new to using BioSTEAM, so I am not sure if there is any error in my code or the TEA file of BioSTEAM. I would really appreciate if you can help me in this regard. Thanks a lot for always helping.

Best,
Uzair

@Uzair1shah, OK! I was able to reproduce the error. The issue is the first argument to a TEA object should be a System object not a TEA subclass:

sys = bst.main_flowsheet.create_system('sys')
tea =  Preprocessing(system=sys, # Not Preprocessing
                  IRR=0.15,
                  duration=(2018, 2038),
                  depreciation='MACRS7',
                  income_tax=0.21, # Previously 35% in published study
                  operating_days=200,
                  lang_factor=3,
                  construction_schedule=(0.4, 0.6),
                  WC_over_FCI=0.05,
                  labor_cost=2.5e6,
                  fringe_benefits=0.4,
                  property_tax=0.11,

@Uzair1shah,

The code you posted does not run for many reasons (e.g., biosteam is not imported, there is no thermodynamic property package). Please include all the code required to reproduce the error.

Can you also post the following:

BioSTEAM version (pip show biosteam).
Python version
Full traceback of the error

It is helpful to remove any irrelevant code too. For example, if the error happens at an earlier line, remove any lines that comes next.

Thanks!

I'm still unable to reproduce your error. I get the following error running your code:

ImportError: cannot import name 'TruckScale' from 'biosteam.units'...

Are you running any other scripts before running this one?

Although the error may be unrelated, you may find it helpful to upgrade to BioSTEAM 2.38.8. The documentation always shows the latest version.

Please refer to this code instead, I have removed the truck scale unit operation. I thought Truck Scale was already in the biosteam unit operations repository, and you might be able to import it. However, it seems like I renamed/created that unit operations. The following code should work for you.

Also, I will try updating the biosteam version and see if that helps with the error.

@Uzair1shah, there are many units listed in your code that are not in BioSTEAM. These units were never in BioSTEAM previously (nor have there been any renaming of unit operations in the last year). When you create new unit subclasses, BioSTEAM automatically registers them in the biosteam.units module, so the reason why your code might work on your side is because those units are being created in another script.

I get the same error with the most recent code you posted:

ImportError: cannot import name 'TruckScale' from 'biosteam.units'

It may be better if you try to minimize your code such that it still reproduces the error you are seeing.

I have removed the unit operations that might be on my side from the import list:

from biosteam.units import VibratingScreen, HammerMill, Mixer, Splitter

These unit operations were already in the biosteam so it should work for you. If it still does not work for you, I can attach scripts for these unit operations as well to reproduce the same error. However, the main code is as follows:

import biosteam as bst
import thermosteam as tmo

@Uzair1shah, OK! I was able to reproduce the error. The issue is the first argument to a TEA object should be a System object not a TEA subclass:

sys = bst.main_flowsheet.create_system('sys')
tea =  Preprocessing(system=sys, # Not Preprocessing
                  IRR=0.15,
                  duration=(2018, 2038),
                  depreciation='MACRS7',
                  income_tax=0.21, # Previously 35% in published study
                  operating_days=200,
                  lang_factor=3,
                  construction_schedule=(0.4, 0.6),
                  WC_over_FCI=0.05,
                  labor_cost=2.5e6,
                  fringe_benefits=0.4,
                  property_tax=0.11,
                  property_insurance=0.11,
                  supplies=0.20,
                  maintenance=0.01,
                  administration=0.005)

Thanks!
