Simulation of propylene+ethylene cascade refrigeration cryogenic box
Thread Content
How does the refrigerant circulate to provide cooling?
It should be so. First, cool it step by step using propylene refrigerants at different temperature levels, and then further cool it using ethylene refrigerants at two different temperature levels. What I don’t know is how to obtain these refrigerants at various temperature levels and how to circulate them. Please provide an explanation
Each refrigerant circulates independently, undergoing heat exchange at the evaporator/condenser
I saw a paper stating that ethylene and propylene are each compressed by their respective compressors, followed by step-by-step cooling and condensation; the resulting condensate then flashes at different pressures to provide refrigerants of various temperature levels for the low-temperature separation cryogenic box. I don’t quite understand how his process is implemented in detail
