Distillation tower control method, storage medium and electronic equipment

Abstract

The invention discloses a rectification tower control method, a storage medium and electronic equipment. The rectification tower control method includes: obtaining material information of the rectification tower, and the material information includes feed flow rate, feed heat and column steam Flow rate; generate material adjustment parameters according to the material information and preset adjustment parameters, and the material adjustment parameters include tower top production flow adjustment parameters, tower bottom production flow adjustment parameters, tower bottom steam flow adjustment parameters and tower top reflux flow matching parameters; adjusting the rectification column according to the material adjustment parameters. In the present invention, by obtaining the material information of the rectification tower, the material adjustment parameters are generated according to the material information and the preset adjustment parameters, and the rectification tower is adjusted according to the material adjustment parameters, so as to prevent the adjustment lag of the rectification tower control parameters and improve the accuracy of the control parameters No need to manually adjust the workload to find the balance point, ensure the smooth operation of the distillation column, and improve work efficiency and safety.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for controlling a rectification tower, a storage medium and electronic equipment. Background technique [0002] The petrochemical industry is the lifeblood of the country's basic industries and plays a very important role. The petrochemical production process mainly includes three aspects: raw material refining, chemical reaction, and product separation and refining. Among them, the separation part is the part that consumes the most energy and is also the main focus of the entire petrochemical production optimization. At present, the method of industrial separation and purification mainly adopts the method of rectification. The smooth operation of the rectification tower is not only related to the quality of the product but also affects the energy consumption of the entire production process. Therefore, the precise and stable control of the parameters of the d...

Problems solved by technology

[0003] At present, the control of the parameters of the existing rectification tower is mainly through the control of parameters such as temperature, liquid level, flow rate, heat and cooling capacity during the operation of the rectification tower, but the control of the existing rectification tower parameters is usually only for the rectification tower. The local parameters of the distillation tower are controlled. For the rectification tower that needs to adjust the load frequently, the feed amount (that is, the load of the rectification tower) is constantly changing. The control of the local parameters of the rectification tower cannot overcome the interference as a whole, which will lead to Problems such as delay in control of distillation column parameters and poor overall operation stability of the distillation column
