FLEXIBLE PROCESS FOR ENHANCING STEAM CRACKER AND PLATFORMING FEEDSTOCKS

摘要

A process for increasing the yields of light olefins or shifting to increase the hydrocarbon components to gasoline blending pools from a hydrocarbon feedstock is presented. The process includes separating a naphtha feedstock to components to a first stream that are more readily processed in a cracking unit and to components in a second stream that are more readily processed in a reforming unit. The process includes the ability to convert components from the cracking stream to the reforming stream, and to convert components from the reforming stream to the cracking stream.

1. A process to increase light olefin and reformate yields, comprising:
passing a first portion of a hydrocarbon feedstream to a fractionation column to generate an overhead stream comprising C6 compounds and lighter components, and a bottoms stream comprising heavier hydrocarbons; passing the overhead stream to a cracking unit. passing the bottoms stream to a separation unit to generate an extract stream comprising normal hydrocarbons, and a raffinate stream comprising non-normal hydrocarbons; and passing the extract stream to the cracking unit to generate light olefins.
