    Since the beginning of this year, the "dual control" of energy consumption in some parts of our country has been excessively vigorous, which has doubled the pressure on coal chemical companies and is at a loss as to what to do
    .


    The author believes that some places do not distinguish between the fuel coal and raw coal used by coal chemical companies.


    At present, this simple method of determining coal consumption indicators for actual energy consumption over the past year is unreasonable
    .


    According to the author's understanding, the coal consumption quotas issued to coal chemical companies in some parts of China in 2021 will be reduced by a certain percentage based on the actual consumption of the company in the previous year


    For example, in the first quarter of last year, a coal-to-liquid company was affected by the epidemic and basically had no production and its energy consumption base was small.
    The local government required the company to reduce its total energy consumption in the first quarter of this year by another 50,000 tons of standard coal year-on-year
    .


    Another large coal-to-olefins company actually uses 320,000 tons of coal per month, while the coal consumption quota issued by the local government is only 250,000 tons.


    The encounters of these two companies are not alone, and it is not just individual places that operate in this way
    .


    During the "13th Five-Year Plan" period, some provinces and regions failed to complete the national energy consumption "dual control" indicator task, and some were interviewed and notified because of their low rankings


    The operation of any enterprise has its own economic laws
    .


    If the output of an enterprise is too low in the production process, the cost of the product will inevitably be high, and the loss will be certain; if the enterprise loses money for a long time, the closure is certain; if the enterprise closes more, the local economy will be affected to a certain extent


    The correct way to "dual control" energy consumption is to reasonably deduct raw coal from the total energy consumption
    .


    Coal chemical industry is the process of converting raw coal into new energy forms such as methanol, oil, natural gas, polypropylene and carbon-containing chemicals.


    Take coal to olefins as an example.
    At present, there is no energy consumption accounting standard for the whole process of preparing polypropylene products from coal-based olefins.
    In some places, fuel coal and raw coal are used as physical energy input for accounting only according to the "National Statistical Report System".
    , Ethylene, propylene, methanol, polypropylene and other carbon-containing chemicals have not been reduced as the physical output of energy, resulting in deviations in comprehensive energy consumption accounting
    .

    In fact, there are two national standards for the comprehensive accounting of coal chemical industry, namely "Coal to Olefins Unit Product Energy Consumption Quota" (GB30180-2013) and "Polypropylene Unit Product Energy Consumption Quota" (GB31826-2015).
    The standard separately calculates the comprehensive energy consumption of the raw coal to olefin section and the comprehensive energy consumption of the olefin synthesis to polypropylene section
    .


    Unfortunately, the current local government has not calculated energy consumption indicators for coal-based polypropylene enterprises in accordance with these two scientific and reasonable standards, which has led to substantial reductions in energy consumption indicators for related enterprises


    This is not only the case for coal-to-olefin companies, but coal chemical companies with other process paths are also facing the same dilemma
