Embodiment Construction

[0138] The method and system of the present invention will be described in detail below in conjunction with the accompanying drawings. The flow chart of the on-line modeling and optimization method suitable for coking crude benzene recovery proposed by the present invention is attached figure 1 shown. The specific implementation steps are as follows:

[0139] 1. Modeling part

[0140] 1.1 Mechanism modeling process of benzene washing process

[0141] Benzene hydrocarbon content a(kg / m 3 ) and the benzene group content c (mass percentage) in the washing oil is expressed as:

[0142] c = 2.24 * a * p 1.25 * Mm * p 0

[0143] In the formula: p 0 is the saturated vapor pressure of crude benzene at the recovery temperature. p is the tower gas pressu...

Abstract

The invention discloses an on-line modeling and optimizing method suitable for recovering coking coarse benzene, and belongs to the field of recovery of coking chemical products. The on-line modeling and optimizing method is characterized by providing a method for one-line modeling and multi-object optimization on coarse benzene recovery. In the invention, a coarse benzene recovery process flow model is established by combining mechanism analysis, multiple regression and system identification modeling, so that the behavior of the system can be accurately described and the requirement for a detection device is reduced; and the coarse benzene recovery multi-object function as an object is provided and the solving is carried out by adopting a particle swarm optimization algorithm so as to obtain the optimized variable of the operation process. The on-line modeling and optimizing method has the advantages of high speed and high efficiency. In addition, by setting an adjustable object weight, the requirement for people on manual adjustment on the specific gravity of single object can be met. The excellent performances of the on-line modeling and optimizing method can be proved through actual production data.

Description

technical field [0001] The invention relates to an online modeling and optimization method for crude benzene recovery in the field of recovery of coking chemical products, in particular to a method suitable for online modeling and multi-objective optimization of crude benzene recovery and software implementation thereof. Background technique [0002] With the in-depth implementation of national energy conservation and emission reduction work, the coking industry is facing more and more pressure on resources and the environment. Adjusting the industrial structure, eliminating backward production capacity, improving pollution control, and taking the road of sustainable development are the directions that the coking industry must persist in and work hard for a long time. In this context, based on the current coking production process and equipment, aiming at green production, reducing emissions, and reducing energy consumption, it will be a practice of great significance to opt...
