Abstract

This embodiment proposes a real-time optimization method and equipment for a continuous reforming device, which specifically includes: establishing a real-time optimization model of the continuous reforming device, obtaining initial parameters for importing the real-time optimization model of the continuous reforming device, and evaluating the validity of the initial parameters. The data to be imported is obtained by processing; the data to be imported is transmitted to the real-time optimization model of the continuous reforming device, the objective optimization function is solved within the range corresponding to the constraint conditions, and the optimal device operating parameters corresponding to the optimal solution of the objective function are determined; Optimize the control parameters of the unit to optimize the current control parameters of the continuous reforming unit. Due to the full use of the advantages of the mechanism model and the data empirical model, the hybrid model can not only reflect the real physical characteristics of the continuous reformer process, but also improve the model extrapolation ability, and improve the real-time optimization solution efficiency and stability performance.

Description

technical field [0001] The invention belongs to the field of data optimization, and in particular relates to a real-time optimization method and equipment for a continuous reforming device. Background technique [0002] By applying the real-time optimization technology of petrochemical industry process, the comprehensive benefit of enterprises can be improved, which has become the consensus of domestic and foreign process industry enterprises such as petrochemical industry. The use of real-time optimization technology not only reduces the repetitive work of device operators, but also reduces the fact that technicians only determine operating values ​​based on design parameters and experience, and cannot achieve optimal operation, which can promote enterprises to greatly save energy and reduce consumption, and greatly improve the market. The reaction speed is very high, which brings considerable economic benefits. [0003] The process real-time optimization technology can mo...

Problems solved by technology

However, most of the real-time optimization of the device depends on the strict steady-state mechanism model. Although the dynamic mechanism model based on complex material balance and energy balance equations can well characterize the physical characteristics of the continuous reformer, it is difficult to meet the actual on-site reforming feed Changes in raw material properties and uncertain operation disturbances often make it difficult to solve, or even fail to converge, which affects online real-time calculation and stability performance

On the other hand, in order to avoid this problem, there are also attempts to use historical data empirical models, which improve real-time performance and stability to a certain extent, but at the expense of model extrapolation capabilities, the actual scope of application is greatly narrowed
