Catalytic distillation simulation, prompts this error, please help!
Thread Content
Using PROII to simulate catalytic distillation, it prompts the following error. * * * error * * * Unit 1, 't1' - volume and weight basis flow rates are only estimates for varied draws. Enter the volume or weight basis rate for draw stream s3 as a specification, then vary the side draw rate to achieve it.
It seems to mean that you can set the flow rate of a logistics, and don't want it to be an indefinite value.
* * * error * * * Unit 1, 't1' - volume and weight basis flow rates are only estimates for varied draws. Enter the volume or weight basis rate for draw stream s3 as a specification, then vary the side draw rate to achieve it. Unit 1, 't1' -The volume or mass flow rate is simply the initial value extracted as a variable. Enter the volume or mass flow rate of stream S3 in the specification, and then set the side flow rate as a variable, ok.
