Successfully developed simulation and optimization system for ethylene cracking furnace

Sinochem News.
com reported on September 10 from the China Petroleum and Petrochemical Research Institute that the ethylene cracking furnace simulation optimization system jointly developed by the institute and Tsinghua University participated in the 2021 China Petroleum Science and Technology Progress Award and passed the public announcement
.

In 2008, after 3 years of technical research, the Lanzhou Chemical Research Center cooperated with Tsinghua University to address the current lack of timely and effective technical guidance in domestic ethylene production.

The development was successful by using computer simulation technology, combined with years of experimental data and the actual operation of industrial furnaces.
The ethylene cracking simulation optimization software EPSOS1.

During the "13th Five-Year Plan" period, the annual domestic ethylene production capacity increased from 22 million tons to 35.
18 million tons
.

In response to the current demand for the development of domestic ethylene production, the Petrochemical Research Institute and Tsinghua University, based on the single-objective optimization software EPSOS in the early stage, aimed at the multi-objective optimization needs of ethylene production, classified the raw materials and optimized the reaction model, and conducted targeted research.

Tian Liang, deputy director of the Refining and Chemical Technology Research Institute of the Lanzhou Chemical Research Center, said that the optimization and stable control of the production process are the prerequisites for ensuring companies to reduce operating costs, improve production efficiency, and build core competitiveness
.

Industrial software is an effective means to solve the above-mentioned problems of enterprises

Compared with foreign software, the all-Chinese interface EcSOS is a model developed based on domestic ethylene raw materials.
The input and operation are very simple.
The optimization target is also based on the actual domestic ethylene production and can be flexibly developed for secondary development
.

Industrial applications show that the calculation time of EcSOS software is less than 0.

　　At present, the technology has been industrially applied in Lanzhou Petrochemical and Sichuan Petrochemical.
In the past three years, it has reduced costs and increased efficiency by more than 100 million yuan, realized the localization of core technology and technology substitution, and is a "petroleum solution" for the digital upgrade of the ethylene production process.

　　The development level of the ethylene industry represents the overall strength of a country's petrochemical industry
.

Industrial software is vividly called the "brain" of production equipment

　　If you want to develop a "Chinese brain" with independent intellectual property rights, you must first have a complete basic database and in-depth process research to support it
.

In 1995, the Lanzhou Chemical Research Center of China Petroleum and Petrochemical Research Institute established the ethylene cracking performance evaluation laboratory

　　In terms of raw material evaluation and optimization, researchers have systematically studied the physical properties of main crude oil and imported crude oil distillates in the western region and the performance of cracking to ethylene
.

In terms of cracking performance evaluation and optimization, they have comprehensively studied the physical properties and cracking performance of oil and gas resources in the western region, refining and chemical equipment by-products, and providing for the storage and refining of ethylene equipment, the optimization of ethylene raw material structure, and the optimization of refining and chemical integration resources.
Technical support
.

　　In terms of industrial furnace calibration and optimization, since 1990, the center has been carrying out industrial cracking furnace calibration and operating conditions optimization work, providing technical support for ethylene enterprises' production and cracking furnace operation optimization
.
After more than 20 years of continuous research, researchers have conducted in-depth research on various furnace types and more than 200 raw materials, and obtained more than 4000 sets of cracking test data and more than 1,500 sets of industrial furnace cracking data
.
The raw material range covers all ethylene raw materials such as ethane, propane, oil field light hydrocarbons, topping oil, light diesel oil, hydrogenated tail oil, and coal chemical naphtha, and a basic database has been established
