Embodiment 1

[0016] The present invention is applied to VOCs monitoring of refinery and chemical equipment, the following combination figure 1 , figure 2 , image 3 To specifically illustrate the specific implementation of this patent.

[0017] Fugitive emissions from refining and chemical equipment can be considered as a surface source, and the device is regarded as a box. If the mass of VOCs flowing into the box, that is, the quality of VOCs transported into the box from the upwind direction with the average wind is Q 1 , the quality of VOCs substances produced by the pollution source in the box is Q, and the amount of VOCs substances flowing out of the box, that is, the amount transported by the average downwind direction is Q 2 ; Neglecting the outflow of the bottom and side walls of the box and the disappearance of ground deposition, the gas flowing upward from the top of the box is considered to pass through the downwind cross-section under the action of the wind, then Q=Q 2 -Q ...

Abstract

The present invention relates to a method for measuring and calculating the VOCS emission of a petrochemical apparatus based on open circuit type infrared monitoring. A purpose of the present invention is mainly to solve the problems of inaccurate measurement and calculation result and difficult measurement and calculation process in the prior art. The technical scheme of the present invention comprises a method for measuring and calculating the VOCS emission of a petrochemical apparatus based on open circuit type infrared monitoring, wherein the diffused gas on the boundary of the apparatus is qualitatively and quantitatively analyzed based on an open circuit type infrared monitoring technology, the gas diffusion research is supplemented, the VOCs diffusion of the petrochemical apparatus is used as a surface source, a box model is established, and finally through formula derivation and calculation, the VOCs emission of the whole petrochemical apparatus is simply and rapidly evaluated, measured and calculated. With the technical scheme of the present invention, the problems in the prior art are well solved. The method of the present invention can be used for the measurement and the calculation of the VOCS emission of the petrochemical apparatus.

Description

technical field [0001] The invention relates to a method for measuring and calculating VOCS emission of refining and chemical equipment based on open-path infrared. 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. In June 2015, the three ministries and commissions of the Ministry of Finance issued the "Pilot Measures for Charging Volatile Organic Compounds", and the Ministry of Environmental Protection issued the "Guidelines for t...
