Fractional distillation pressure control for separation of aromatic alkylation product |
| abstract |
A pressure control system and method for utilization in a process for effecting the alkylation of an aromatic hydrocarbon with a normally gaseous olefinic feed stream. The system is intended to control the pressure within a fractional distillation column which initially recovers the alkylaromatic product from unreacted aromatic hydrocarbons and a minor quantity of normally gaseous paraffinic contaminants contained in the olefinic feed stream. The system is especially advantageous in the boron trifluoride-catalyzed alkylation of benzene with ethylene, the latter containing minor quantities of ethane which must necessarily be vented, or removed from the system. |
