Hello, while using the EOS of Lee Kesler Plocker for the degassing of oil, I got one vapour phase and two liquid phases as a result. Can anyone please explain why I got two liquid phases? (Knowing that when I use the EOS of Peng Robinson I get only one liquide phase but a flow of vapour that...

MortenA yes I did, I set the inlet at 1m (which is the case in reality) and the outlet at 0.5m. pierreick good point, I will try it and see.

Yes, the elevation difference is what drives the liquide to come out of the tanks.

Thanks for your remark, I just added a schematic in HYSYS. I hope it is clear now.

Hello, after multiple attempts to empty five tanks in my HYSYS simulation, I could't do it. The tanks are filled with oil to a level of 80%, the valve of filling is fully closed, and the valve of the emtying is fully open. I installed a PID Controller, and i chose as a set point 5% than 50% but...

Hello, would anyone explain for me how does a Digital Control Point work? i didn't understand the signification of the lower dead band, the higher dead band and the threashold. Knowing that when I put a certain value in the threashold for tank filling, the level of liquid in that tank exceeds...

Thank you for your answers. I finally get it.

Hello, I am working on a simulation on HYSYS, and I found two types of flowrate: - Std ideal liq vol flow in m3/h - Liq vol flow @std cond in m3/h I would like to know the difference between theme. Thank you in advance.
