    A few days ago, the reporter learned from China Coal Shaanxi Yulin Energy and Chemical Co.


    Technological transformation to save energy and reduce consumption

    "We insist on technological innovation and energy-saving technological transformation, improve energy efficiency, reduce energy consumption and carbon dioxide emissions


    For example, by implementing the cooling transformation of the air cooling system of the turbo-generator unit, the exhaust steam pressure of a single unit can be reduced by 3~5kPa under high temperature weather conditions, each unit can increase the load by about 10MW, and reduce the annual coal consumption by 2,400 tons; DMTO device Optimizing reaction operations, optimizing high-performance catalysts, and adopting technologies such as C4 pre-deposition can save 159,000 tons of standard coal and reduce carbon dioxide emissions by 413,300 tons per year; using the third-generation coal slurry concentration technology, the concentration of coal slurry increases by 3 Percentage points, the annual oxygen consumption can be reduced by 61.


    In addition, they have implemented more than 50 technical transformations, including methanol capacity expansion transformation, MTO residual boiler transformation, gasification deaerator technical transformation, thermal power waste steam recovery, and real-time monitoring of the operating status of large units and key pumps


    These technical transformations have brought significant effects to the stable operation of the device and energy saving and carbon reduction


    Refinement management requires benefits

    Sun Zongli said that the company insisted on paying equal attention to management and energy-saving transformation, and continuously improved the level of refined energy management, which has become another "sharp weapon" for energy conservation and efficiency enhancement


    Optimize equipment energy saving and efficiency


      Energy efficiency management system upgrade


      Tap water saving potential


      A new model of intelligent empowerment

     New model of intelligent empowerment New model of intelligent empowerment

      As the first pilot demonstration enterprise of intelligent manufacturing in the coal chemical industry, the company adheres to digital empowerment in production and operation practice, and helps enterprises improve production efficiency and reduce consumption through digital transformation and intelligent application


      Sun Zongli introduced that they innovatively implemented the intelligent optimization project of the steam, circulating water and methanol synthesis carbon-hydrogen ratio of the whole plant, as well as the optimization and transformation of the operation process of DMTO, gasifier and other devices, and improved production efficiency through automation and intelligence


      In order to further improve energy utilization efficiency, reduce energy consumption and carbon emission reduction, the company will continue to implement energy conservation and carbon reduction actions, strengthen energy conservation management throughout the process, actively promote a clean and low-carbon energy structure, accelerate the deployment of new energy, and explore the utilization of carbon dioxide resources.
