Problems solved by technology

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 present invention relates to an industrial cracking furnace cracking product value maximization model construction method. In olefin production enterprises, based on steam cracking experiment data, an industrial cracking furnace cracking product prediction model is established, actually operating cracking depth data of the industrial cracking furnace is adopted to correct and check the established prediction model, and a cracking furnace cracking product value maximization model is established based on the corrected and checked model, and is adopted to optimize operation of the cracking furnace, such that the total market price of cracking products produced by the cracking furnace is maximized.

Description

technical field [0001] The invention relates to a cracking furnace in petrochemical industry, and more specifically, to an optimization method for the operation of a cracking furnace in a petrochemical production device. 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 development, steam cracking technology has beco...
