Research on the Contributing Sources to the Atmospheric PM_(2.5) from Petrochemical Enterprises

In order to study the contributing units to the atmospheric PM2.5 from the manufacturing process in the petrochemical enterprise,a particular petrochemical enterprise with a capacity of tens of millions ton is studied. Based on the formation mechanisms of PM2.5,the contributing units in the petrochemical enterprise are recognized,including the primary fine particulate matter sources as well as the sources that contributed to the formation of both the organic and the inorganic secondary fine particulate matter. What's more,it is confirmed that the quality of the oil products in the petrochemical enterprise also has an important influence on the formation of PM2.5. And finally,some emitting-reducing measures of PM2.5 are put forward in accordance with the contributing units found in the petrochemical enterprise.
