SYSTEMS AND METHODS OF PRODUCING AROMATIC PRODUCTS

摘要

Systems and methods for producing aromatic products are provided. An aromatic stream is provided with aromatic compounds and olefins. The olefins are reacted with aromatic compounds to form colored bodies, and the aromatic stream is distilled to produce an overhead stream and reboiler stream. The colored bodies are in the reboiler stream, and the reboiler stream is passed through an absorbent to remove the colored bodies.

主权项

1. A method of producing toluene, the method comprising the steps of:
processing a feed naphtha stream with a naphtha processing unit to produce a processed naphtha stream; separating the processed naphtha stream into an aromatic stream and a non-aromatic stream, wherein the aromatic stream primarily comprises toluene and benzene; reacting olefins remaining in the aromatic stream to produce colored bodies; distilling the aromatic stream to produce an overhead stream and a reboiler stream, wherein the reboiler stream comprises toluene and colored bodies; and removing the colored bodies from the reboiler stream by passing the reboiler stream through an absorbent, wherein the absorbent selectively absorbs colored bodies over toluene.
