Embodiment 1

[0072] like figure 1 , the embodiment of the present invention provides a method for identifying VOCs components of a production device, the method comprising:

[0073] S1) Divide different production devices in the production area into multiple process sections, and arrange multiple VOCs component sampling equipment in each process section;

[0074] S2) Obtain the VOCs component samples in the production area through the plurality of VOCs component sampling devices, calculate the relative components of the VOCs components samples, and filter the relative components of the part, and then filter the The relative amounts of the components are statistically calculated to obtain the VOCs component distribution data corresponding to each of the different production devices.

[0075] The relative amount of components can be selected as a characteristic ratio between components, such as the ratio of aromatics between components; the distribution data can include statistical data (su...

Embodiment 2

[0113] Based on Example 1, the characteristic compound ratio method is a method for qualitatively identifying pollution sources based on the obvious differences in the ratios of different chemical components in different emission sources. The ratio method has been successfully applied in the identification of source classes. The ratio can be used as a parameter to characterize the source class. The ratio between aromatic components is a very important identification index in the identification of oil fingerprints. Therefore, the ratio method can be used for classification and identification.

[0114] Principal Component Analysis: It is a method commonly used in statistics to reduce dimensionality. When counting data, a large number of variables will increase the complexity of calculations and increase the difficulty of problem analysis. There may be a certain correlation between multiple variables, and information overlap will occur during calculation. Using the method of pr...

Embodiment 3

[0132] Based on Example 2, the VOCs component spectrum database of the main equipment of the petrochemical refinery was established, and the characteristic ratio of the aromatic components was extracted. Common facilities in refineries include atmospheric and vacuum units, catalytic cracking, catalytic reforming, catalytic hydrogenation, delayed coking, sewage treatment plants, chemical production, storage tank farms, etc. Different production units are divided into multiple process sections, according to different production Devices are divided according to production raw materials, processing technology, product requirements, etc.

[0133] Collect as many VOCs samples from different devices as possible, and use GC-MS analysis instrument to obtain the composition of VOCs samples, including 107 compounds including alkanes, alkenes, alkynes, aromatics, chlorinated hydrocarbons, oxygen-containing organic compounds, and sulfides. According to the principle of data processing, sam...

Abstract

The invention provides a method and system for identifying a production device based on VOCs components, and belongs to the technical field of VOCs monitoring and identification. The method comprises the following steps: dividing different production devices in a production area into a plurality of process sections, and arranging a plurality of VOCs component sampling devices in each process section; obtaining VOCs component samples of the production area through the multiple pieces of VOCs component sampling equipment, calculating the component relative quantity of the VOCs component samples, filtering the component relative quantity of part of the VOCs component samples,counting the filtered component relative quantity, and obtaining VOCs component distribution data corresponding to each production device in the different production devices. The method is used for monitoring the volatile organic compounds and identifying the volatile organic compounds of different production devices.

Description

technical field [0001] The present invention relates to the technical field of VOCs monitoring and identification, in particular to a method for identifying VOCs components in production equipment, a system for identifying VOCs components in production equipment, a method for identifying production equipment using VOCs components, and a method for identifying VOCs components in production equipment. A VOCs component identification production device system, an electronic device, and a computer-readable storage medium. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOCs) have photochemical activity and are important precursors for the formation of PM2.5 and ozone pollution. This important precursor will have a serious impact on the atmospheric environment and human health, and it has also attracted increasing attention . The country has successively issued a number of policy documents, clearly requiring the strengthening of online monito...
