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 o

Abstract

Embodiments of the invention provide a real-time optimization method and apparatus used for a continuous reforming device. The method specifically includes the following steps: establishing a real-time optimization model of the continuous reforming device, obtaining initial parameters for introducing the real-time optimization model of the continuous reforming device, and performing effective treatment on the initial parameters to obtain to-be-introduced data; transmitting the to-be-introduced data to the real-time optimization model of the continuous reforming device, solving a target optimization function within a range corresponding to a constraint condition, and determining an optimal device operation parameter corresponding to an optimal solution of a target function; and performing optimization based on a current control parameter of an optimal device control parameter to the continuous reforming device. Since advantages of a mechanism model and a data experience model are fullyperformed, a mixed model can reflect real physical characteristics of a process of the continuous reforming device, the model extrapolation capability is also improved, and real-time optimization solution efficiency and stability performance are improved.
