Ethylene oxide industrial chain to low-carbon extension

The business agency reported on February 17th that Liaoning Aoke Chemical Co., Ltd. learned on February 15 that the company and the Yangzhou Chemical Industrial Park Management Committee formally signed an ethylene oxide and carbon dioxide derived low-carbon fine chemical new material project. Park's letter of intent, Liaoning Aoke will adopt international leading technology to build 200,000 tons/year of ethylene oxide, 300,000 tons/year of ethylene carbonate/dimethyl carbonate, and 300,000 tons/year of green low-carbon epoxy derivative fine chemicals. New Material items. At the beginning of the “Twelfth Five-Year Plan”, the production of ethylene oxide derivatives began to accelerate overall.

According to Zhu Jianmin, president of Aoke Group, the project started with the ethylene production of ethylene oxide, and through the adoption of a series of energy-saving and efficient processes to strengthen new technologies, the highly reactive ethylene oxide reacts with inert carbon dioxide to produce ethylene carbonate and A series of important fine chemical new material monomers such as dimethyl carbonate. This green low-carbon technology will gradually replace the highly toxic synthetic route and build a green chemical industrial chain with significant economic and social benefits.

At present, the by-product of the industrial production of ethylene oxide in the world is mainly CO2. With the significant increase in the production of ethylene oxide in China in the past two years, the quantity of by-product CO2 has also increased dramatically. If it is directly discharged into the air, not only It is a waste of resources, but it also has adverse effects on the environment and ecology. After the project is completed, it can digest 300,000 tons of carbon dioxide each year. In addition to its significance in energy conservation and emission reduction, the project can also fill the gap in domestic ethylene oxide derivatives market and create a new road for the structural adjustment of the petrochemical industry.

Ethylene oxide is an important fine chemical raw material and can be used to derive a variety of fine chemical products such as ethylene glycol, non-ionic surfactants, ethanol amines, and glycol ethers. Zhu Jianmin told reporters that there are more than 5,000 downstream ethylene oxide products in the world, while China has only developed more than 300 varieties and varieties cannot meet the needs of the domestic market.

The new project to be built by Liaoning Aoke will not only realize the efficient use of CO2 to produce ethylene oxide, but also enrich the domestic ethylene oxide downstream product chain. According to Zhu Jianmin, the ethylene carbonate produced by the project is a low-toxicity, multi-purpose chemical with a high flash point and safe storage and transportation. It is a very good intermediate and can be used as an intermediate product or directly as a finished product. . Dimethyl carbonate is emerging as a basic chemical raw material with low pollution and wide application. It is called the cornerstone of organic synthesis in the 21st century, and the amount of dimethyl carbonate is increasing at a rate of 20% every year. The development of green low-carbon epoxy-derived fine chemicals and new materials projects has opened up a huge space for the future development of AOC. The project will use dimethyl carbonate and ethylene carbonate as raw materials to further deep-process high-value-added downstream products.
