Hi everyone. I've to do an investigation project of methane liquefaction.
I propose do this using a 3 steps-cascade refrigeration system, and the refrigerants are Propane, Ethylane and Nitrogene. When I do the first step of the refrigeration system with Propane, and I simalute it in ProII, it gives to me an irregular behavior, because when i put in the evaporator (2cell HX), i get that in the entrace of the compresor I have a mix of the refrigerant, besides the cold line in the 2cell HX, is doing the process with a constante temperature. That does have any sense.
So, does anyone know why I'm getting this? Your help will be useful.
PD: Sorry if I have any writing error.
