Catalytic reforming energy-saving system, catalytic reforming energy-saving method and catalytic reforming reaction system

Abstract

The invention relates to the technical field of catalytic reforming, and discloses a catalytic reforming energy-saving system, a catalytic reforming energy-saving method and a catalytic reforming reaction system. The catalytic reforming energy-saving system comprises a high-pressure absorption tank, a reformed oil stabilizing tower and a first heat exchanger, wherein the high-pressure absorption tank is communicated with a base solution output pipe; the base solution output pipe is communicated with the feed port of a reformate stabilizing tower; the reformate stabilizing tower is communicatedwith a base oil output pipe; the base oil output pipe serves as a heat source pipeline; and the base solution output pipe serves as a cold source pipeline and is connected with the first heat exchanger. The catalytic reforming energy-saving method comprises a step of performing heat exchange on a base solution generated by the high-pressure absorption tank with base oil generated by the reformatestabilizing tower as a heat source. The catalytic reforming reaction system comprises the catalytic reforming energy-saving system. According to the catalytic reforming energy-saving system, the catalytic reforming energy-saving method and the catalytic reforming reaction system, system load can be reduced, system energy consumption is reduced, and resource conservation is achieved.

Description

technical field

[0001] The invention relates to the technical field of catalytic reforming, in particular to a catalytic reforming energy-saving system, an energy-saving method and a catalytic reforming reaction system. Background technique

[0002] As the reforming unit of the naphtha processing unit, it mainly uses naphtha as the raw material to produce reformed oil rich in aromatics, which is used as the raw material of aromatics and gasoline blending components, and at the same time rich in hydrogen and a small amount of liquefied gas. Generally, it mainly consists of three units: raw material pretreatment, reforming reaction and catalyst regeneration. Among them, the pretreatment unit includes three parts: pre-fractionation, pre-hydrogenation and stripping. The naphtha raw material from the naphtha stabilization system enters the pre-fractionation tower for fractionation. 1. After being condensed and cooled by the water cooler, part of it is used as tower top reflux, a...
