Hello Engineers,
I Need your Help to Simulate (by Hysys) a Distillation Separation Process to separate 1-hexene from other components of 1-butene stream.
Components of 1-butene stream:
1-butene (Alpha-Olefin)
n-butane (Paraffin)
1-hexene (Alpha-Olefin) [This One is Goal]
hexane (Paraffin)
octene (Olefin)
I simulated a PFD but have problem in Separation of 1-hexene & hexane because of similar boiling points (63 and 68 Celsius). Distillation Separates them in Very High Condensor and reboiler duties (for example 800 kW).
After Search about it, I Understand it Needs Azeotropic Distillation (with another agent) or L-L Extraction Distillation (with another agent) to Distance their Boiling points to have a Simple Separation with desirable Cond. and reb. duties. But I Have Not any idea to Simulate Azeotropic Distillation or L-L Ext. Distillation for these 1-hexene & hexane.
Please Help me to Solve it...
Thanks
