Dear experts, what is the liquefaction temperature of ethylene at 4.3 MPa? How to calculate

Reply #22020-01-16

The liquefaction temperature is the boiling point at this pressure. 1.71℃

Um... could you please tell me how to calculate it?

I calculated it using the “Chemical Engineering Calculations” app that I developed. The formula is very complex and requires iteration, which essentially rules out manual calculation.

By checking the property data sheet for ethylene, one can find the temperature corresponding to its saturated vapor pressure of 4.3 MPa. Not all parameters need to be calculated by oneself! ! !

Using a different algorithm and recalculating, the value is 2.1°C. It’s basically similar to what I calculated last time.
