Embodiment 1

[0068] According to the furnace type of GK-V cracking furnace, the value maximization model of steam cracking naphtha cracking products in GK-V cracking furnace is established. The modeling process is as follows.

[0069] 1 Experimental data of steam cracking

[0070] According to the GK-V industrial cracking furnace and operating conditions, a variety of naphthas were collected and steam cracking experiments were carried out in the steam cracking evaluation simulation device of Sinopec Beijing Research Institute of Chemical Industry. Under the cracking product yield, the experimental data is collected to establish the GK-V cracking furnace steam cracking reaction sample database. The database content includes naphtha (specific gravity, ASTM distillation range, group composition), operating conditions (feed amount, water-oil ratio, XOT, COT), cleavage product yield. Related steam experiment analysis instruments and equipment are as follows:

Abstract

The invention relates to a naphtha industrial cracking furnace value maximization model construction method. In ethylene production enterprises, based on naphtha steam cracking experiment data, a naphtha cracking furnace cracking product yield prediction model is established, and naphtha industrial cracking furnace n-pentane yield 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 naphtha cracking furnace cracking product value maximization model is established, and is adopted to optimize operation of the naphtha cracking furnace, such that the total value of cracking products produced by the industrial naphtha 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, more specifically, a method for constructing a value maximization model of a cracking furnace in the naphtha industry. 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, butadiene) and "triphe...
