Abstract
A process is presented for increasing the aromatics content in a reformate process stream. The process modifies existing processes to change the operation without changing the reactors or heating units. The process includes bypasses to utilize heating capacity of upstream heating units, and passes the excess capacity of the upstream heating units to downstream process streams.
Claims9
A process for increasing the aromatic content of a hydrocarbon stream, comprising:
- passing the hydrocarbon stream through a series of reforming reactors and reactor feed heaters, wherein the reactors feed heaters generate a heated stream and at least one of the heated streams is split into a first portion and a second portion, with the first portion passed to a reforming reactor to generate a reforming reactor effluent stream;
- and
- wherein the second portion of the heated stream is combined with a downstream reforming reactor effluent stream and the combined stream is passed to a downstream reactor feed heater, to generate a reactor product stream with increased aromatic content.
