Jufeng New Energy: open up a new path of kinetic energy conversion in coal chemical industry


Release time:

2019-06-11

"In this project, we purify coke oven gas to produce hydrogen peroxide and produce propylene oxide, which is the first example in the domestic coking industry. It is the organic combination of coal chemical industry, salt chemical industry and petrochemical industry. It is a specific practice of high-end chemical industry and a typical example of the transformation and upgrading of the chemical industry." On June 4th, in Juye Jufeng New Energy Co., LTD., the general manager Li Minchang said that the direct oxidation process of propylene oxide used in the project of producing hydrogen peroxide and propylene oxide by comprehensive utilization of coke oven gas of 1 million m3/d replaced the traditional process of chloroalcohol process of propylene oxide, which reduced the pollution emission brought by the production of the enterprise. The production process and technology is the first in China.

The production process and technology is the first in China.

It is understood that hydrogen peroxide and propylene oxide are basic chemical raw materials. Hydrogen peroxide is widely used in paper making, printing and dyeing, food, electronics and chemical synthesis industries. Currently our country has become the largest production and consumption country of hydrogen peroxide in the world. Propylene oxide is a very important organic compound raw material, is the third largest propylene derivative, mainly used in the production of polyether polyol, propylene glycol and various non-ionic surfactants, among which polyether polyol is the production of polyurethane foam, insulation materials, elastomers, adhesives and coatings, and other important raw materials. All kinds of nonionic surfactants are also widely used in petroleum, chemical, pesticide, textile, daily chemical and other industries. "There is a wide market demand for our project products and there is a large market space for improvement in terms of economic, social and ecological benefits." Lee Minchang said.

Innovation is the primary driving force for development. Jufeng New Energy has carried out extensive cooperation with Yangzhou Puret Technology Development Co., Ltd. with strong technical force, and has the technical research and development support from Tianjin University, Southeast University, China University of Mining and Technology and other universities and scientific research teams. Not only that, the general manager Li Minchang is also a well-known scholar in the field of coal chemical industry and petrochemical industry.

On the same day, the reporter saw in Jufeng New Energy, hydrogen extraction workshop, sewage tank, research and development center and other parts of the basic engineering has been completed, a variety of devices, equipment is also being installed. "We plan to complete the hydrogen extraction project by the end of September, and the hydrogen peroxide purification project will be ready for driving by the end of October." Lee Minchang introduced.

According to reports, after the completion of the project, 1 million cubic meters of coke oven gas will be used every day to produce 750,000 tons of hydrogen peroxide (27.5% concentration) and 200,000 tons of propylene oxide, which will effectively improve the utilization efficiency of coking by-product resources, transform the enterprise from traditional coal chemical industry to new coal chemical industry and new materials, and optimize and upgrade the industrial structure. Promote the rapid development of industrial circular economy.

"Our project is a chemical project of comprehensive utilization of coke oven gas recovery, which is conducive to sustainable production development and industrial upgrading of coal chemical enterprises. After the project reaches full production, it will drive the development of Juye County industrial Park and increase the added value of production of upstream and downstream enterprises." Li Minchang said that it is expected to achieve annual sales revenue of 4 billion yuan, profit and tax of 1.3 billion yuan, after the completion of the project, 400 people will be employed.
