METHOD AND APPARATUS FOR REDUCING AN AROMATIC CONCENTRATION IN A HYDROCARBON STREAM

摘要

Methods and apparatuses for reducing an aromatic concentration in a hydrocarbon stream are provided. In an embodiment, a method for reducing an aromatic concentration in a hydrocarbon stream includes saturating aromatics in the hydrocarbon stream to form a low aromatic hydrocarbon stream comprising no more than 2 weight percent (wt%) aromatics. Further, the method includes passing the low aromatic hydrocarbon stream through an adsorption zone to remove aromatics therefrom to form an aromatic-depleted product stream comprising less than 10 weight parts per million (wppm) aromatics.
