I was wondering if there is a method for adding up several energy streams. For example if I'm simulating a turbine, by means of different expanders, it would be useful to visualize the total energy associated with the machine.

Have any of you simulated urea and ammonia systems? (e.g. urea decomposition to ammonia). What could be a suitable property package?

Hello everyone. I was wondering if there is a way to move the unit-op palette from the bottom side of the screen to another position, lets say to the right. I have not been able to do so

Hi Vincent, I think a specific unit operation does not exist, and you should try to simulate the ejector putting together other unit-ops, namely expander, mixer, compressor. Maybe this paper could inspire some ideas: https://pdfslide.net/documents/ejector-modeling-in-hysys.html

yes, obviously I understood that it works like this :) it could be an improvement to make it possible to set freely one of the flow rates, or alternatively block the second cell

Hello everyone, I have a question about the Splitter UnitOp. Suppose that we have a feed stream (e.g. 100 kg/h) and two outlet streams. We want to set the mass flowrate of one of the outlets (e.g. to 20 kg/h), leaving the other free to change according to the possible inlet changes. See the attached file. It seems that this works ONLY if we set the value of the outlet 1. If we try to set flowrate of outlet 2 the value is ignored, and in some cases the mass balance is no longer verified. Am I doing...

Thanks Daniel, I will study the code.

sorry, there was a typo in the script. the acquisition of the input properties should have been: M1 = in1.GetProp("totalflow", "Overall", None, "", "mass")[0] m1 = in1.GetProp("totalflow", "Overall", None, "", "mole")[0] f1 = in1.GetProp("fraction", "Overall", None, "", "mole") P1 = in1.GetProp("pressure", "Overall", None, "", "")[0] T1 = in1.GetProp("temperature", "Overall", None, "", "")[0] H1 = in1.GetProp("enthalpy", "Overall", None, "", "mass")[0] but at this point I wonder why it worked...
