Abstract
A process is presented for recovering the components for a gasoline blending pool to meet the E70 specifications. The process includes the separation of the naphtha feedstock into a light naphtha stream and a heavy naphtha stream. The process further includes separating the light naphtha stream to recovery high quality non-normal hydrocarbons having normal boiling points above 70° C., and to separate for adding to the feed to the reforming unit, hydrocarbons that have lower boiling points.
Claims28
A process for improving stream cracker feed and processing gasoline blending components, comprising:
- passing a naphtha feedstream to a fractionation column to generate an overhead stream comprising hydrocarbons with normal boiling points below 90° C., and a bottoms stream comprising heavies;
- passing the overhead stream to a separation unit to generate an extract stream comprising normal hydrocarbons and a raffinate stream comprising non-normal hydrocarbons;
- passing the extract stream to a cracking unit;
- and
- passing the bottoms stream to a reforming unit.
A process for improving naphtha stream cracker feedstock and processing gasoline blending components, comprising:
- passing a naphtha feedstream to a fractionation column to generate an overhead stream comprising hydrocarbons with normal boiling points below 75° C., and a bottoms stream;
- passing the overhead stream to an adsorption separation unit to generate an extract stream comprising normal hydrocarbons and a raffinate stream comprising non-normal hydrocarbons;
- passing the raffinate stream to a second fractionation column to generate an overhead stream, a side stream and a second bottoms stream;
- passing the extract stream to a cracking unit;
- and
- passing the bottoms stream to a reforming unit to generate a reformate.
