Abstract

The present invention relates to an industrial cracking furnace cracking product value maximization model construction method. In petrochemical enterprises adopting industrial cracking furnaces as leading production devices, based on steam cracking experiment data, a cracking furnace cracking product yield prediction model is established, and industrial cracking furnace target cracking product mole content data is acquired and is adopted to correct and check the established prediction model, such that a calculation result of the prediction model and an actual operation result of the industrial cracking furnace are the same; and based on the corrected and checked model, a cracking furnace cracking product value maximization model is established, and is adopted to optimize operation of the cracking furnace, such that the total value of petrochemical products produced by the industrial cracking furnace is maximized so as to effectively improve income of the petrochemical production enterprises.

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] The petrochemical industry is a pillar industry of the national economy, and petrochemical products (referred to as petrochemical products) are widely used in various fields of the national economy and are important to promote the development of the national economy. Most of the petrochemical intermediate products and petrochemical products are based on low-carbon olefins and aromatics. The feedstock hydrocarbons used in low-carbon olefins and aromatics account for about three-quarters of the total consumption of feedstock hydrocarbons in petrochemical production. Low-carbon olefins are mainly composed of ethylene, propylene, and butadiene, and aromatics are mainly composed of benzene, toluene, and xylene. In the petrochemical...
