    [ Policies and Regulations of Chemical Machinery Equipment Network ] In order to improve the prevention and control of volatile organic compounds in the petroleum refining industry and promote the improvement of ambient air quality, the Shandong Provincial Department of Ecology and Environment has organized and compiled the "Guidelines for Viable Techniques for the Prevention and Control of Volatile Organic Compounds in the Petroleum Refining Industry (Request) Opinion Draft)", now soliciting opinions from relevant units
    .

     
    Chemical Machinery and Equipment Network Policies and Regulations Chemical Machinery and Equipment
    Volatile organic compounds (VOCs) are important precursors that cause composite pollution in cities characterized by ozone (O3) and fine particulate matter (PM2.
    5) pollution.
    Some VOCs have carcinogenic, mutagenic, and teratogenic effects, and can directly affect Harm to human health
    .

     

    In recent years, compound pollution characterized by O3 and PM2.
    5 pollution has become the main problem of the atmospheric environment in Shandong Province.
    Compared with the control of particulate matter, sulfur dioxide, and nitrogen oxide pollution, Shandong Province’s VOCs management foundation is weak, which has become a constraint in Shandong Province.
    The bottleneck of continuous improvement of air quality
    .
    Shandong Province is a major petroleum refining province.
    It has the largest refining capacity in the country, accounting for about 30% of the national capacity.
    The petroleum refining industry accounts for 20.
    6% of the province’s emissions of VOCs.
    The VOCs pollution prevention and control capabilities of related companies are uneven.
    There is an urgent need to formulate technical guidelines for pollution prevention and control based on the characteristics of VOCs emissions from enterprises in the petroleum refining industry in Shandong Province
    .

     

    This guide proposes feasible technologies for the prevention and control of volatile organic compounds in the petroleum refining industry in Shandong Province
    .
    This guide can be used as a reference for the environmental impact assessment of Shandong petroleum refining industry enterprises or production facilities construction projects, the formulation and revision of Shandong volatile organic pollutant emission standards, the management of pollution permits, and the selection of pollution prevention technologies

      Process unorganized waste gas
    .
    1.
    Enterprises should adopt fully enclosed, continuous, automated and other production technologies, as well as high-efficiency processes and equipment, to reduce unorganized waste gas emissions from processes
    .
    2.
    The delayed coking device should be retrofitted with closed decoking technology to realize the closed operation of the whole process of petroleum coke, and the exhaust gas produced is concentratedly transported to the exhaust gas treatment device
    .
    3.
    The safety valve, the pressure regulating valve temporary venting exhaust emissions should be closed unorganized collection, install and control facilities, treated to meet GB 31570, the DB 37 / 2801.
    6, DB 37/3161 emissions requirements
    .

     

      Device and sealing point
     

      1.
    Enterprises should reduce or change the sealing points of equipment to control the fugitive emissions of VOCs according to the production situation
    .
    On the pipeline
     

      Try to use welding methods to reduce flange connections
    .
    On the premise of meeting process requirements and ensuring safety, plugs or blind plates should be installed on all open pipelines or open valves
    .
    2.
    Enterprises should use pumps, pipe valves, compressors , filters , centrifuges, drying equipment, etc.
    that have no leakage or small leakage
    .
    For materials with a true saturated vapor pressure greater than 27.
    6 kPa, a leak-free pump should be used
    .
    3.
