Abstract

The invention relates to a method for measuring and calculating a discharge amount of petrochemical enterprise fugitive emission source VOCS. The method mainly solves the problem of poor calculating accuracy of the prior art. The method comprises setting a monitoring route along a fugitive emission source down wind direction through combination of an open-circuit infrared monitoring technology and meteorological conditions, carrying out continuous real-time monitoring, carrying out analysis and processing on the monitoring data result, selecting a characteristic compound, calculating a VOCs equivalent concentration, building a mathematical model and a calculation formula and acquiring a fugitive emission source total VOCs discharge amount and discharge amounts of ingredients of VOCs. The method solves the above problem and can be used for measuring and calculating the discharge amount of petrochemical enterprise fugitive emission source VOCS.

Description

technical field [0001] The invention relates to a method for measuring and calculating VOCS emissions from fugitive emission sources of petrochemical enterprises. Background technique [0002] VOCs (volatile organic compounds) in the atmosphere are not only the main precursors of photochemical smog pollutants, but also an important source of toxic and harmful organic components in atmospheric fine particles, making an important contribution to the formation of haze, and some VOCs themselves have Toxicity and carcinogenicity have a great negative impact on human health. With the continuous deepening of my country's air pollution control and increasingly serious environmental problems, the impact of VOCs on the atmosphere has attracted increasing attention. [0003] In 2015, the Ministry of Finance issued the "Pilot Measures for Charging Volatile Organic Compounds" (Cai Shui [2015] No. 71, hereinafter referred to as "Charge Measures"), and its Annex 2 "VOCs Emission Calculati...
