      Hi!

      I am trying to study a helium liquefaction cycle through a thermodynamic analysis: energetic and exergetic analysis. The system operates in a steady state considering that the portion of the liquefied gas is replaced through the backup gas. So, I have some doubts, if you can help me, please?

      1. What would be the best equipment to model the system after gas expansion? I ask because I thought of a separator vessel with the output of the liquefied gas going towards a source and the portion of the gas in vapor returning to the system.
      I would like to model the system in such a way that it would be possible to visualize the portion of the gas that was liquefied and the portion of the gas that returns to the system in the saturated state. But I couldn’t because of an error that I still don’t quite understand. Something related to the matrix system.

      2. Another doubt I have is that I don’t have all the system data, but through thermodynamic calculations, I think it’s possible to determine. My initial idea would be to validate my model in Cycle-Tempo with some of the experimental data I have. But when I model the system in the software with the adopted assumptions, I get an error response that tells me that I didn’t enter enough data.

      I am attaching a picture of how I modeled the system.

      Best regards!
