Methods for producing aromatic hydrocarbon mixtures

Abstract

The invention relates to a method for producing aromatic hydrocarbon mixtures from naphtha feedstock (100 or 100a) consisting of the steps of feeding naphtha feedstock (100 or 100a) and gaseous LPG (10a and 10lb) into a feed / feed heat exchanger of a reactor (200 or 300) to obtain mixture (102 or 102a). The mixture (102 or 102a) is fed into a minimum of one and a maximum of three reactors via integrated heat exchangers to produce an aromatic-rich hydrocarbon mixture, the flow is fed into the reactor's secondary / feed heat exchanger (200 or 300) before being transferred to the cooling bath (203), the flow is cooled in the cooling bath (203), the cooled flow (107) is pumped into the first stage splitter (204) to capture the light gases, Transfer the remaining liquid to the second stage fork (206) and separate the remaining liquid to obtain LPG (10lb) and feed the flow directly into the stabilizer (207) to separate the gas, LPG (101 c) and the polymerization product, wherein the polymerization product is a mixture of aromatic hydrocarbons.
