[Guide] Technical Strategy for Continuous Monitoring of Non methane Total Hydrocarbon Emission from Waste Gas of Fixed Pollution Sources (Trial) (Draft for Comments) is an instrument application standard related to HJ1013-2018, and is also the first online VOCs analyzer application standard issued by the Ministry of Ecology.

Volatile organic compounds (VOCs) are the key points in China's air pollution control in recent years. Due to the short rise time, messy technical plans, and many application scenarios, ultra-low emission dust meters require multiple standards for monitoring volatile organic compounds, including: measurement samples (ambient air, pollution source exhaust gas), measurement components (VOCs, non methane total hydrocarbons), measurement technologies (gas chromatography, GC-MS, Fourier infrared, etc.) Measurement methods (laboratory, portable and online).

Now, the introduction of VOCs analysis standards in China is as follows:

As for the online environmental monitoring instruments in China, the Ministry of Ecology and Environment will generally issue two standards: the ultra-low CEMS system is an instrument technical standard that standardizes the relevant functions of the instrument; One is the instrument application standard, which is used to standardize the construction, work and handling of instruments.

As for online VOCs standards, there are now instrument technical standards for the measurement of ambient air components and non methane total hydrocarbons in exhaust gas, but the standards for instrument application are still missing.

Recently, the Ministry of Ecology and Environment released the Technical Strategy for Continuous Monitoring of Non methane Total Hydrocarbon Emissions from Fixed Pollution Sources (Trial) (Draft for Comments), which is the instrument application standard related to HJ1013-2018 and the first online VOCs analyzer application standard issued by the Ministry of Ecology.

The preparation team collected the domestic and foreign standard data and instrument information, and conducted field research in Shandong, Shanghai and other places with relatively sophisticated application. According to the survey, the automatic monitoring system that has been equipped in the country is mainly aimed at non methane total hydrocarbons, so this technical strategy is determined as the "Technical Strategy for Continuous Monitoring of Non methane Total Hydrocarbon Emission from Fixed Pollution Source Exhaust Gas", and this technical strategy only requires the selection of FID to measure the continuous monitoring system of non methane total hydrocarbon emission from fixed pollution source exhaust gas.
