Calculation of ethylene vaporization heat
Thread Content
Dear seniors, I have a question. How to calculate the heat required to vaporize liquid ethylene at -101 degrees into gaseous ethylene at 30 degrees using 3 kg of steam? Detailed calculation methods are required. . . I hope to receive guidance from all the seniors! ! !

Anyone who uses Aspen can answer this question in just 5 seconds. If doing it by hand, one needs to look up the heat of vaporization for heat balance calculations @longkui1990
Acrylic acid is used as an intermediate; it is heated by steam, which in turn heats liquid ethylene (-101 degrees).
If the pressure remains constant, it’s the sensible heat of conversion of liquid ethylene to gaseous ethylene, plus the latent heat of ethylene at that state, then the sensible heat required to raise the gas temperature to 30°C, and finally the latent heat at 30°C: lol:lol
