Embodiment Construction

[0107] The present invention will be further analyzed below in conjunction with the accompanying drawings and specific embodiments.

[0108] Such as figure 1 As shown, a process schematic diagram of a continuous catalytic reforming unit, its process production flow is:

[0109] The reforming feed mixes with the circulating hydrogen from the high-pressure vapor-liquid separation tank, exchanges heat with the reforming reaction product through a heat exchanger, and then enters the heating furnace 1. After being heated to a certain temperature in the heating furnace, it enters the first heavy The whole reactor R1 is in contact with the catalyst for reforming reaction; the reaction products and unreacted raw materials from the first reforming reactor R1 enter the heating furnace 2 for heating, and then enter the reactor R2 and heating furnace 3 in sequence , reactor R3, heating furnace 4, and reactor R4. The reaction product from the last reactor R4 exchanges heat with the reform...

Abstract

The invention discloses a real-time optimal control system and method for a continuous catalytic reforming device. The system of the present invention is divided into a data collection module, a data conversion module, a data processing module, a human-computer interaction module, a central processing module, and a predictive control module, wherein the central processing module is based on reforming kinetics, thermodynamics, material balance, energy balance, etc. Based on the basic principle, a relatively complete mechanism model is established, and real-time optimal control is achieved through the optimal control algorithm. The present invention constructs a real-time optimal control system in a modular form for the continuous catalytic reforming device, and achieves the goal of real-time optimal control through the mutual cooperation of each module and the combination of mechanism modeling and optimal control algorithm. Through the optimization of the entire process in the continuous catalytic reforming unit, the optimal solution of the system comprehensive index is effectively obtained, which is of great significance for chemical plants to improve product yield and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to a real-time optimization control system and method for a continuous catalytic reforming device. Background technique [0002] Catalytic reforming refers to the transformation of the light gasoline fraction (or naphtha) obtained from crude oil distillation into high-octane gasoline (reformed gasoline) rich in aromatics under the conditions of temperature, pressure, hydrogen and the presence of a catalyst. The process of producing liquefied petroleum gas and hydrogen by-products; it is one of the main processing techniques in the oil refining industry, an important means to improve the quality of gasoline and produce petrochemical raw materials, and one of the effective methods to solve the shortage of high-octane gasoline and aromatic hydrocarbon raw materials one. [0003] As the world's energy shortage intensifies, the competition for resources will become more and more...
