Description
Technical Field
The application relates to the field of establishing methods of industrial Volatile Organic Compounds (VOCs) source component spectrums, in particular to an establishing method of a petrochemical industry Volatile Organic compound source component spectrum based on an emission source item.
Background
The establishment of the manmade source VOCs component spectrum in China is the basis for compiling VOCs species emission lists and realizing scientific formulation and accurate implementation of national and industrial reaction activity-based control strategies. The petrochemical industry is one of key contributors of artificial emission in China and is also key work of emission reduction of industrial source VOCs for a long time, and the establishment of the specification of the VOCs source component spectrum has important significance for implementing deep emission reduction in the industry.
The existing establishment methods of VOCs component spectrums in the petrochemical industry mainly comprise two types. The first method, which takes petrochemical enterprises as a union, pays attention to the pollution characteristics of VOCs nearby. Generally, researchers set sampling points around petrochemical complexes, measure the environmental concentration and component characteristics of the VOCs through an online or offline monitor, characterize daily and seasonal changes thereof, conduct pollution source analysis or strong inversion of pollution sources, and evaluate environmental impact and health risks. However, the method only focuses on the VOCs emission of the whole petrochemical enterprises, and does not consider the VOCs composition spectrum emission characteristics of the internal emission sources and specific process units of the enterprises at all. The second method is to take different process units in a petrochemical enterprise as specific objects, such as process units of dynamic and static sealing point leakage, storage tank, loading, wastewater treatment and the like, and research the VOCs source composition spectrum characteristics of the different process units of the enterprise. However, for the petrochemical industry of a plurality of complicated VOCs emission source items, researchers have a disadvantage in applying the method: the VOCs component spectrum in the industry is mostly acquired by performing arithmetic mean after normalizing all process unit samples, and the contribution of different discharge amount of each process unit to the VOCs component spectrum is not considered.
Therefore, the establishment of the VOCs component spectrum in the petrochemical industry based on the emission source item at present is not effectively combined with the actual emission of VOCs emission sources in all links of an enterprise, the emission intensity of VOCs of different emission sources is neglected, and the characteristics of the VOCs source component spectrum in the petrochemical industry cannot be accurately reflected, so that in the field, research on a standardized establishment method of the VOCs source component spectrum in the petrochemical industry needs to be urgently developed, thereby providing important technical support for further deep, scientific and accurate emission reduction of the industry.
