Abstract:
1. A process for producing aromatics from a naphtha feedstream comprising: passing the feedstream to a fractionation unit, thereby generating a first stream comprising light hydrocarbons, a second stream comprising intermediate hydrocarbons, and a third stream comprising heavy hydrocarbons; passing the first stream to a first reformer, operated at a first set of reaction conditions, thereby generating a first reformer effluent stream; passing the second stream to a second reformer, operated at a second set of reaction conditions, thereby generating a second reformer effluent stream; passing the third stream to a third reformer, operated at a third set of reaction conditions, thereby creating a third reformer effluent stream; passing the first reformer effluent stream and the second reformer effluent stream to a fourth reformer, operated at a fourth set of reaction conditions, thereby generating a fourth reformer effluent stream; passing the third reformer effluent stream and the fourth reformer effluent stream to a fifth reformer, operated at a fifth set of reaction conditions, thereby generating a fifth reformer effluent stream; passing the fifth reformer effluent stream to an aromatics extraction unit, thereby creating a purified aromatics stream and a raffinate stream.
