炼油厂罐顶轻烃的逸散研究

Study on Volatillzation of Hydrocarbons from the storage tanks in the refinery

测定了炼油厂罐区内轻烃罐顶的挥发烃组成，结果表明：出油罐罐顶逸散的烃类化合物浓度要高于静止罐，对于同一罐罐顶逸出烃的浓度罐壁处要高于中央位置．逸出烃类化合物主要为烷烃、芳烃、环烷烃和烯烃，逸出的高含量芳烃是大气污染的主要人为源之一．

Hydrocarbons volatilizing from storage tanks were determined. The hydrocarbons concentration of the top on the pouring tank is larger than that of the stationary tank, and bydrocarbons concentration of near top border is larger than of the center of tank. The volatilizing hydrocarbons form one of the largest sources, especially for aromatic hydrocarbons.
