Research On Petrochemical Corporation Odor Pollutions Assessment And Criterion Establishment

Nowadays, odor pollutions and odor complains is much more than ever, and have already aroused abroad attention. Dushanzi Petrochemical Corporation's refinery was selected as the research object, studied odor pollution assessment technology and odor criterion establishment systematically.According to the particularity of Dushanzi Petrochemical Corporation's refinery, sampling the whole refinery, using DynaScent(Australia) olfactometer analazed odor concentration and odor intensity, got environmental odor concentration and odor intensity, according to webber-Fechner formula established the relationship of odor concentration and intensity, discussed odor environmental criterion of Petrochemical Corporation's refinery, and then integrated with abroad correlative criterions, established the odor environmental impact concentration and intensity criterion. Based on field's odor environment source data, from the odor particulates studied odor impact's factor, Analyzed the calculation model of odor dispersion and discussed the dispersion coefficients'correction correlatively, established the odor dispersion's calculation model. Integrated with software VB and MATLAB established odor dispersion's calculation procedure's bag, it can calculate and analyze the odor point resource and area resource's dispersion using graphics.Lastly, using the measure data of locale odor sources predicted Dushanzi Petrochemical Corporation's refinery's odor pollution, and the predicted results were verified. it was found that the prediction data and the field data had good consistency.
