论浮顶罐大呼吸非甲烷总烃排放计算公式参数取值

目前原油库建设环评需预测非甲烷总烃对周边居民的影响，进而提出卫生防护距离。大连、岙山等国家战略储备基地根据预测提出的卫生防护距离对居民进行拆迁安置．致使工程经济可行性大为降低。采用实测与美国推荐大气预测模式对浮顶罐非甲烷总烃对环境质量的影响发现其差异较大。文章在分析其差异的基础上，对污染源强的参数取值进行了详细论证。以实测为基础，论述了计算公式中参数的取值依据，进而论证了当前浮顶罐运行段采取不防腐，依靠原油自身物性，即可达到防腐和减少非甲烷总烃的双重效果。

Discussion on Calculated Parameters Value of Non-methane Hydrocarbon Emission in Floating Roof Tank Big Breathing

At present, the construction of Crude Oil Tank Farm needs the EIA which forecasts the non-methane hydrocarbon （NMHC） on the impact of the surrounding residents, and then makes the health protection distance. Dalian, Aoshan, and other national strategic reserve base make resettlement of residents according to the health protection distance, it results in the fall of economic feasibility. There are great differences between the measures and the atmospheric forecast mode which is recommended by the United States. The article demonstrated the calculated parameters value on the basis of analysis the differences, and then dissertated the gist of the value on the formula. At last, the article proved anti-corrosion and reduction of NMHC could be achieved relying on crude oil of its own.
