Override separator parameters from python script

[Ja Eddouibi]

Hello again,
Thank you for your reply.
I want to override temperature and pressure during the simulation of a flash separator but from python script. I read a lot of comments in this forum but i didn't found how to do this. I hope that you have somme suggestions for me.
Thank you

Hi Ja,
you can easily find and paste the commands you need for this task with the Insert Snippet button in the Script Manager. Anyway, this should be what you were looking for:

# Define Object Property: OverrideT

obj = Flowsheet.GetFlowsheetSimulationObject('SEP-004')
obj.OverrideT = True # Override Sep. Temperature

# Define Object Property: OverrideP

obj.OverrideP = True # Override Sep. Pressure

# Define Object Property: FlashTemperature

obj.FlashTemperature = 373.15 # Seperation Temperature in K

# Define Object Property: FlashPressure

obj.FlashPressure = 202650 # Seperation Pressure in Pa

Just adding to Stefan's answer, if you override T and/or P, you'll need to connect an energy stream to the separator so DWSIM will calculate the energy balance of the separator and put the energy flow residue on it.
