    "Olefin is an important chemical raw material.
    Plastics, auto parts, and space shuttles used in daily life are all produced from olefins
    .
    " On May 25, the reporter walked into Pucheng Clean Energy Chemical Co.
    , Ltd.
    to work.
    The staff pointed to the transparent glass bottle in front of him and introduced that the small white particles inside were polyethylene and polypropylene made from coal and processed through production
    .
    If the continued downturn is the new normal in the coal industry, then looking for new economic growth points is an important mission undertaken by Pucheng Clean Energy and Chemical Company
    .
    Pucheng Clean Energy and Chemical Company, located in the Weibei Coal Chemical Industrial Park, is a new coal chemical enterprise established in November 2008 with an investment of 20 billion yuan and is mainly responsible for the processing and production of coal-based olefin products
    .
    Since the production of qualified polyolefin products through the entire process at the end of 2014, in 2015, the cumulative production of methanol was 1.
    556 million tons, polyolefins were 290,700 tons, operating income was 2.
    906 billion yuan, and profits were 206 million yuan; as of the end of April this year, the cumulative production of polyolefins With 184,900 tons of olefins and sales revenue of 1.
    503 billion yuan.
    .
    .
    Extending the industrial chain and creating high value-added coal chemical products, Pucheng Clean Energy and Chemical Company has become an important pole in the chemical territory of Shaanxi Coal Group
    .
    "4 million tons of raw coal can produce 680,000 tons of olefin products.
    Although the current market price is low, the market price of polyethylene is still around 7,000 yuan, and the market gap is large, so there is no need to worry about sales
    .
    The production capacity reached its peak in May this year.
    It’s 58,000 tons, which is close to 60,000 tons
    .
    " Liu Peirong, chairman and party secretary of Pucheng Clean Energy Chemical Company, told reporters that in order to serve this project, Shaanxi Coal Group invested 7.
    9 billion yuan to build an underground coal pipeline from Shenmu.
    727 kilometers, the high-quality bituminous coal from the Shennan mining area is continuously transported
    .
    The company adopts the world's first set of DMTO-II (a new generation of methanol to produce low-carbon olefins) device.
    The production process uses coal to produce methanol, and then methanol to olefin products
    .
    It is expected that another methanol-to-olefin product production process will be built in the future, and methanol will be purchased directly from the plant area within 50 kilometers.
    This will not only integrate internal resources and directly convert the surplus methanol to olefins, but also reduce production links and maximize benefits.

    .
    According to the development history of the industry, coal chemical industry can be divided into two categories: traditional coal chemical industry and modern coal chemical industry
    .
    Traditional coal chemical industry mainly includes coal coking, coal-based urea, synthetic ammonia and other chemical fertilizers, while modern new coal chemical industry targets clean energy and chemicals, mainly including coal-to-liquid, coal-to-methanol, coal-to-olefin, and coal.
    Making ethylene glycol and so on
    .
    At present, most domestic and foreign petroleum is used to produce olefin products, but more than 60% of China’s petroleum needs to be imported.
    The energy structure is rich in coal, poor in oil, and low in gas.
    Therefore, coal-to-olefins has become a new direction for the development of a new coal chemical industry, and the industry has a broad prospect
    .
    At the same time, the "cold winter" of the coal market has also prompted the traditional coal chemical industry with potential overcapacity and serious environmental threats to undergo structural adjustments and industrial upgrades
    .
    "The market for high-end products polyethylene and polypropylene is in strong demand, and the price is one to two times higher than that of traditional products
    .
    " Liu Peirong said that China's coal chemical products are still in the initial stage of development, and the industrial chain can be further extended to produce higher added value.
    Products
    .
    Whether from the perspective of national security, economic security, energy security, coal industry transformation, and industrial upgrading, the prospects and potential for the development of new coal chemical industries are great
    .
    "To reduce overcapacity, we must not only do a good job in subtraction, but also do a good job in addition, extend the industrial chain, increase the added value of products, and point out the direction for the development of the enterprise
    .
    As a'recruit' in the Shaanxi Coal Group, our total number of employees is less than 1,400.
    , The average age is only 28 years old, mastering advanced production technology and management skills, just like the industry we are engaged in, we represent the future development direction
    .
    " Liu Peirong said
