In order to solve the contradiction between supply and demand in the domestic market for basic organic chemical raw materials such as ethylene, the ethylene industry has implemented the second and third rounds of reconstruction and expansion. Although the production capacity of the ethylene industry has been significantly improved, the source of cracking raw materials for cracking furnaces—the production capacity of oil refineries without a corresponding increase

Abstract
The invention relates to a method for constructing an industrial cracking furnace value maximization model. In an olefin production enterprise, a cracking furnace cracking product yield prediction model is established based on steam cracking experimental data, and the target cracking product yield data of the industrial cracking furnace is collected and used for calibration. The prediction model established by the kernel, so that the calculation results of the prediction model are consistent with the actual operation results of the industrial cracking furnace; The cleavage product or the total value of the cleavage product is maximized.
Description
technical field [0001] The invention relates to a method for optimizing the operation of a cracking furnace in a petrochemical production device, and more specifically, to a method for constructing a value maximization model of an industrial cracking furnace. Background technique [0002] Tubular cracking furnace, referred to as cracking furnace, is the main device for producing basic organic chemical raw materials such as ethylene, propylene, butadiene, aromatics (benzene, toluene, xylene), among which 98% of the world's ethylene is produced by steam cracking furnace produced. Ethylene, propylene, butadiene, benzene, toluene, and xylene are the most important basic organic chemical raw materials. The products and derivatives produced by them are widely used in various fields of the national economy and play a very important role in promoting the development of the national economy. . [0003] Steam cracking technology began in the 1920s. After years of continuous developm...
