PROCESS FOR PRODUCING AROMATICS FROM WIDE-BOILING TEMPERATURE HYDROCARBON FEEDSTOCKS

摘要

The present invention relates to methods and systems useful for producing aromatics-rich products from liquid hydrocarbon condensates. The production system includes a hydroprocessing reactor, an aromatization reactor system and a hydrogen extraction unit. The methods for producing the aromatics-rich products include introducing a wide boiling range condensate into the hydroprocessing reactor and operating the aromatics production system such that the hydroprocessing reactor forms a naphtha boiling temperature range liquid product. The liquid hydrocarbons produced in accordance with the present invention may optionally be further processed using a hydrogen extraction unit to produce a high-purity hydrogen fraction.

1. A method for producing hydrocarbon products from a wide boiling range condensate, the method comprising the steps of:
introducing the wide boiling range condensate and hydrogen into a hydroprocessing reactor of an aromatics production system, where a volume ratio of the hydrogen to the wide boiling range condensate introduced is in a range of from about 0.01 to about 10; operating the aromatics production system under conditions such that the hydroprocessing reactor forms both a light product gas mixture and a naphtha boiling temperature range liquid product, where the naphtha boiling temperature range liquid product consists of naphtha boiling temperature range liquid product components having boiling point temperatures in a range of about 30° C. to about 240° C.; passing the naphtha boiling temperature range liquid product to an aromatization reactor system and the light product gas mixture passes to a hydrogen extraction unit; operating the aromatization reactor system under conditions appropriate for forming one or more hydrocarbon products; passing hydrogen to the hydrogen extraction unit and at least a portion of the non-aromatic liquid product to the aromatization reactor system; producing hydrogen and a mixed hydrogen-poor gas in the hydrogen extraction unit, wherein the mixed hydrogen-poor gas comprises no less than 70% by weight C1 to C5 alkanes; and passing the hydrogen to the hydroprocessing reactor.
