Abstract

The invention discloses an oil refinery hydrogen pipe network pressure adjusting method, and belongs to the technical field of petroleum refining, a hydrogen supply unit is connected with a hydrogen using unit through a hydrogen pipe network, and a pressure controller is arranged on a tail end hydrogen outlet pipeline, connected with the hydrogen pipe network, of the hydrogen supply unit; the pressure change condition of the hydrogen pipe network is judged according to the opening degree of the pressure regulating valve of the pressure controller, the system automatically controls the reforming reaction temperature and the reforming feeding flow in the hydrogen supply unit according to the opening degree of the pressure regulating valve so as to regulate the hydrogen production amount of the hydrogen supply unit, automatic pressure regulation of the hydrogen pipe network is achieved, human interference is not needed, and the system is simple in structure and convenient to operate. Labor intensity is relieved, great pressure fluctuation of the hydrogen pipe network is avoided, and pressure stability of the hydrogen pipe network is achieved.

Description

technical field [0001] The invention relates to the technical field of petroleum refining, in particular to a method for regulating the pressure of a hydrogen pipe network in an oil refinery. Background technique [0002] The adjustment of the hydrogen pipeline network pressure in the existing refinery is generally carried out by the production dispatcher, who notifies the relevant devices to adjust the production according to the pressure change of the pipeline network. When the pressure of the hydrogen pipeline network is low, notify the reforming unit or hydrogen production unit to increase the processing capacity and produce more hydrogen to maintain the pressure of the hydrogen pipeline network basically constant; or notify the hydrogen device to take measures to reduce hydrogen consumption and maintain the hydrogen pipeline network The pressure remains largely unchanged. vice versa. This method of operation increases the workload of scheduling, and the pressure of th...
