Abstract
Methods and systems for petrochemical feedstream purification are described herein. The methods generally include providing a petrochemical feedstock, wherein the petrochemical feedstock includes a concentration of polar impurities, contacting the petrochemical feedstock with a washing agent to remove at least a portion of the polar impurities therefrom, separating the washing agent from the petrochemical feedstock to form a purified feedstock and passing the purified feedstock to a petrochemical process. In one embodiment, the petrochemical feedstock includes benzene and the washing agent includes water.
