Cryogenic separation |
| abstract |
A process for separating a hydrocarbon mixture containing an alkene, a corresponding alkane having the same number of carbon atoms as the alkene and at least one heavier hydrocarbon component comprises the steps of: a) feeding the hydrocarbon mixture to a first distillation tower (40) having an upper reflux stage; b) recovering a first overhead vapor stream (40V) rich in alkane and alkene from the first distillation tower (40) and passing said overhead vapor stream (40V) to a middle distillation stage of a second distillation tower (50); c) recovering a second overhead vapor stream (50V) rich in alkene from the second distillation tower (50); d) adiabatically compressing the second overhead vapor stream (50V) and passing said compressed vapor to a reboiler stage (50B) of the second distillation tower (50) to cool and condense the compressed vapor and heat a liquid reboiler stream. |
