Abstract
Processes and apparatuses for producing para-xylenes are provided. The processes comprises providing a reformate stream comprising aromatic hydrocarbons to a reformate splitter to provide a reformate bottoms stream and a reformate overhead stream. A portion of the reformate bottoms stream is passed to a para-xylene separation unit for separating para-xylene, wherein the portion of the reformate bottoms stream is passed to the para-xylene separation unit without an intermediate step for removal of olefins.
Claims6
A process for the production of para-xylene, wherein the process comprises:
- a) providing a reformate stream comprising aromatic hydrocarbons to a reformate splitter to provide a reformate bottoms stream comprising C7+ aromatic hydrocarbons and a reformate overhead stream comprising C7− aromatic hydrocarbons;
- and
- b) passing a portion of the reformate bottoms stream to a para-xylene separation unit for separating para-xylene, wherein said portion is contacted with an adsorbent under adsorption conditions to provide a xylene extract stream comprising para-xylene and a raffinate product stream,
- wherein the portion of the reformate bottoms stream is passed to the para-xylene separation unit without an intermediate step for removal of olefins.
