Objective: To establish health protection zone standards for petroleum processing industry.
Methods: The intensity of characteristic pollutants from fugitive emission were estimated by the inverse method of ground concentration through field survey and monitoring for representative petroleum processing industry, which was calculated health protection zone by using the model of atmospheric diffusion.
Results: Characteristic pollutant of fugitive emission source from petroleum processing industry was confirmed as hydrogen sulfide. When local average wind speed in the past five years was less than 2, 2-4 m/s and more than 4 m/s respectively and meanwhile the scale of petroleum processing industry was less than 8 million tons, the recommended value of health protection zone were 900, 800, 700 m respectively. Besides, when the scale of petroleum processing industry was more than 8 million tons and in the same wind speed level, the recommended value of health protection zone were 1200, 1000, 900 m respectively.
Conclusions: Recommended value of health protection zone for petroleum processing industry was reasonable and feasible through revising and improving of the version of 1987's standard.
