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, 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 cracking products produced by the industrial cracking furnace 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 model for maximizing the value of cracking products 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 y...
