Abstract

The invention relates to a heavy raw material industrial cracking furnace value maximization model construction method. In ethylene production enterprises, based on heavy raw material steam cracking experiment data, a heavy raw material cracking furnace cracking product yield prediction model is established, and yield data of cracking products having a carbon number of less than or equal to 4 of a heavy raw material industrial cracking furnace 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 heavy raw material cracking furnace cracking product value maximization model is established, and is adopted to optimize operation of the heavy raw material cracking furnace, such that the total value of cracking products produced by the industrial heavy raw material 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 a heavy raw material industrial cracking furnace. Background technique [0002] At present, 99% of the world's total ethylene production is produced by steam cracking furnaces, and the current and future newly increased ethylene production capacity is mainly produced by steam cracking furnaces. While the ethylene plant produces ethylene, the by-products of propylene, butene, butadiene, and aromatics (benzene, toluene, xylene) become the main source of basic raw materials for the petrochemical industry. In addition to the production of ethylene in the ethylene plant, 70% of the propylene, 90% of the butadiene, and 30% of the aromatics come from the by-products of the ethylene plant. Based on the total amount of "triene" (ethylene, propylene, but...
