Problems solved by technology

However, estimating the operating parameters and cracking raw materials required by the ethylene cracking unit requires a lot of manpower and material resources, and the estimated results are rough. When the cracking raw materials change, the operating parameters of the unit cannot be adjusted in time.

Embodiment Construction

[0063] A method for predicting and optimizing the allocation of ethylene cracking raw materials in this specific embodiment is based on a cracking furnace group of a cracking device of a petrochemical company as an example, and calculates the ratio of raw material resources of all cracking furnaces. On the basis of the high yield of high-yield products, raw material supply price and product price, the optimization is carried out according to the demand for ethylene raw materials with the highest high-yield yield and the lowest equivalent ethylene cost of the ethylene plant. The specific calculation basis and optimized cracking raw material configuration results are shown in the attached Shown in Table 1 (this table shows the cracking raw material system and optimization results of the company in a certain month). The specific implementation steps are as follows:

Abstract

The invention discloses a forecasting and optimizing method for ethylene cracking material configuration. A method of combining industrial operation data feature extraction and a cracking reaction mechanism is adopted, and cracking characteristics of each cracking furnace and cracking material conditions are synthesized, so that modeling and forecasting are carried out on cracked products, and types and loads of cracking materials used by the cracking furnace are optimized, and therefore, optimized configuration of the cracking materials and economic benefit optimization of all devices are achieved.

Description

technical field [0001] The invention relates to the field of chemical engineering, in particular to a method for predicting and optimizing the allocation of raw materials for ethylene cracking. Background technique [0002] The ethylene industry is the leader in the petrochemical industry. Trienes (ethylene, propylene, butadiene) and triphenyls (benzene, toluene, xylene) produced by ethylene plants are the basic raw materials for the petrochemical industry. Ethylene production has always been the measure of a country’s A sign of the level of petrochemical development. my country's ethylene industry persists in actively assimilating and re-innovating imported technologies and adheres to the road of connotative development based on technological transformation, which has made many fruitful achievements in the development of my country's ethylene technology. Through the reconstruction and expansion of ethylene plants, my country's ethylene plants will develop in the direction ...
