Abstract
A process for the alkylation of aromatic hydrocarbons such as cumene and ethylbenzene is disclosed. A portion of the effluent stream from an alkylation reactor passes through an indirect heat exchanger to transfer heat to a flashed stream containing the product aromatic hydrocarbons. The heat exchanger recovers the exothermic heat of reaction from the effluent stream for use elsewhere in the process. This method of heat exchange is especially useful in alkylation processes where the temperature of the effluent stream is relatively low, such as where the alkylation reactor contains a zeolite catalyst.
