This article considers the alternatives for treatment of the raffinate produced at a unit for the extraction of benzene-containing fractions and the products of catalytic reforming. The method for aromatization of gasolines by catalytic reforming is widely used in industry. In the case of targeted use of the obtained aromatic hydrocarbons as a petrochemical raw material in order to isolate benzene the benzenecontaining part of the reformate goes through a technological extraction stage, during which a by-product, catalytic reforming raffinate, is formed. The paper presents the results from modeling and calculations of the combined operation of catalytic reforming with continuous catalyst regeneration and an isomerization unit and also proposes an optimal raffinate processing scheme that makes it possible to increase the yield of marketable products.

本文考虑了处理在提取含苯馏分和催化重整产物的装置中产生的萃余液的替代方案。通过催化重整对汽油进行芳构化的方法在工业上得到广泛应用。在有针对性地使用所获得的芳烃作为石油化工原料以分离苯的情况下，重整油的含苯部分经过技术萃取阶段，在此期间形成副产物催化重整萃余液。
