Petrochemical processes

摘要

Petrochemical processes, including reforming processes are described herein. The reforming processes generally include introducing an input stream to a reforming unit having a reforming catalyst disposed therein, wherein the input stream includes a naphtha having an N+2A value of from about 65 to about 85 and contacting the input stream with the reforming catalyst and hydrogen to form an output stream.

1. A petrochemical process comprising: introducing a first input stream to a cracking unit, wherein the first input stream comprises a virgin naphtha feedstock, wherein said virgin naphtha feedstock is a former reformer input stream;
cracking the virgin naphtha feedstock within the cracking unit to form a first output stream comprising light olefins and pygas; passing the pygas from the cracking unit to an extraction unit; separating benzene and toluene from the pygas within the extraction unit; recovering a raffinate from the extraction unit having a higher N+2A than the virgin naphtha feedstock; passing the raffinate from the extraction unit to a reforming unit having a reforming catalyst disposed therein; contacting the raffinate with the reforming catalyst to form a second output stream; and recovering the second output stream from the reforming unit.
