Abstract
Process and apparatuses for producing benzene and para-xylene from a reformate stream is provided. The process comprises separating the reformate stream to provide a first stream comprising Cand lighter hydrocarbons and a second stream comprising aromatic hydrocarbons. The second steam is provided to a reformate splitter to provide a reformate bottoms stream comprising Caromatic hydrocarbons and a reformate overhead stream comprising Caromatic hydrocarbons. The reformate overhead stream is passed to an aromatics extraction unit to provide an aromatics extract stream comprising benzene and toluene and a raffinate stream comprising non-aromatic hydrocarbons. The reformate bottoms stream and one of the first stream and the raffinate stream is passed to an olefin reduction zone, wherein the reformate bottoms stream and one of the first stream and the raffinate stream are contacted with an olefin saturation catalyst under olefin saturation conditions to produce an olefin-treated reformate stream.
