Ethylene tower

Thread Content

Why is the process going through the ethane deethanization subcooler, then the deethanization vaporizer, and finally the cold box in the bottom of the ethylene distillation tower?

It seems to be related to the boiling points of ethylene and ethane; the boiling point of ethylene is around -48 degrees, while that of ethane is around -80 to -90 degrees
