AERMOD模型在石油化工环境影响评价中的应用

Application of AERMOD Model to Environmental Impact Assessment of a Petroleum and Petrochemical Plants

以某炼油厂新建聚丙烯酰胺装置为研究对象,介绍了AERMOD模型的基本原理、操作过程和所需基本资料,并利用该模型对周围大气环境造成的影响进行了逐日逐时的预测。结果表明:预测结果与监测值具有很好的一致性,说明该模型可成功应用于国内石油化工行业区域环境影响预测。

The article applies AERMOD model to a certain oil refinery plant,evaluating and analyzing the impact of ammonia emission on atmospheric environment.It gives a brief introduction of the AERMOD model on its basic principle,operation process and other necessary information.And it conducts day to day evaluation on the atmospheric impact by the polyacrylamide device newly established in the oil refinery plant,determines the ground level concentration/hour,identifies the location of the ammonia emissions from the refinery and draws a map of concentration distribution.It evaluates the largest concentration in different places of the region and how it distributes in different places.Finally the article points out the impact of the oil refinery plant on surrounding environment.
