摘要： A separation arrangement for a cumene process that operates with a relatively wet feed to an alkylation zone and relatively dry feed to a transalkylation zone reduces utilities and capital expenses for the separation and recycle of distinct wet and dry components by using an arrangement that first separates effluent from the trans alkylation and alkylation reaction zone in a benzene column before performing light ends and drying in a downstream depropanizer column. The arrangement uses a portion of the net overhead stream from the benzene column as a wet recycle stream for return to the alkylation reaction zone and sends another portion of the benzene net overhead to the depropanizer to supply a dry benzene recycle for the trans alkylation reaction zone.

摘要： A process for producing alkyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. One portion of the transalkylation reaction zone effluent passes to an alkylation reaction zone where an aromatic substrate is alkylated to the desired alkyl aromatic. At least a portion of the alkylation reaction zone effluent and another portion of the transalkylation reaction zone effluent pass to a product recovery zone. This process decreases the capital and operating costs of recycling aromatic substrate to the transalkylation and/or alkylation reaction zone while maintaining operational flexibility. This process is well suited for solid transalkylation and alkylation catalysts. Ethylbenzene and cumene may be produced by this process.

摘要： A process for producing ethyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. Portions of the transalkylation reaction zone effluent pass to a multibed alkylation reaction zone where aromatics in the transalkylation reaction zone effluent are alkylated to the desired ethyl aromatics. At least a portion of the transalkylation reaction zone effluent passes to an alkylation bed other than the first alkylation bed of the multibed alkylation reaction zone. This process decreases the capital and operating costs of recycling the aromatics in the transalkylation reaction zone effluent. This process is well suited for solid transalkylation and alkylation catalysts. Ethylbenzene may be produced by this process.

摘要： 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.
