Abstract
A process for producing an alkylaromatic compound includes contacting a dilute olefin feed with a lean oil stream containing aromatic compound and alkylaromatic compound in an absorption zone to provide an alkylation reaction stream containing aromatic compound, alkylaromatic compound and olefin. The alkylation reaction stream is reacted under alkylation reaction conditions in an alkylation reaction zone to provide an effluent containing the aromatic compound and alkylaromatic compound. The effluent of step is separated into the lean oil stream which is recycled to the absorption zone and a product portion from which an alkylaromatic product is recovered.
