China China’s MEE, Guidelines for Continuous Emissions Monitoring of NMHC Emitted from Stationary Sources (Trial)

On March 2, 2020, The Ministry of Ecology and Environment of China (MEE) announced “Technical Guidelines for Continuous Emissions Monitoring of Non-Methane Total Hydrocarbon in Waste Gas Emitted from Stationary Sources (Trial)”. The Guidelines were formulated to thoroughly implement the automatic monitoring and to prescript the installation of automatic monitoring infrastructures for volatile organic compounds (VOCs). The main contents are as follows.

 

Requirements for installation of monitoring equipment

  1. System configuration
    Non-methane hydrocarbon continuous emissions monitoring system (also called NMHC-CEMS) is composed of a non-methane hydrocarbon monitoring unit, a monitoring unit of emitted smoke and gas, a data collection and processing unit.
  2. Technical performance requirements
    Technical performance should be satisfied with the requirements described in “Specifications and test procedures for non-methane hydrocarbons continuous emission monitoring system in stationary sources” (HJ 1013).
  3. Monitoring station requirements
    Performance of the monitoring station should be satisfied with the requirements described in “Specifications for continuous emissions monitoring of SO2, NOx, and particulate matter in the flue gas emitted from stationary sources” (HJ 75)
  4. Installation location requirements
    Installation location should meet the requirements in HJ 75.
  5. Installation and construction requirements
    The requirements for installation and construction of the continuous monitoring system in HJ 75 should be met.

 

Requirements for operation and management

  1. Managers
    Managers of NMHC-CEMS must compile management procedures based on instructions and technical requirements of NMHC-CEMS, and acquire the knowledge of maintenance.
  2. Maintenance
    Maintenance of NMHC-CEMS should meet the requirements in HJ 75.
  3. Routine calibration
    Routine calibration should meet the relevant requirements in HJ 75.
  4. Quality assurance
    Daily quality assurance ensures the stable operation of NMHC-CEMS.

In addition, the “Guidelines” clearly described the data processing and the method of recording, etc.
