watson特征因子(K)是否随着石油组分相态的变化而变化？ 很专业的回答你这个问题着实累死人, 呵呵. http:///books?id ... &hl=zh-cn#ppa11 ,m1 看下面的专业解释吧: nelson (1966) pointed out the truth of the latter statement in an interesting graph of characterization factor vs. boiling point, shown in figure 2-3. (这个是在书中的, 我不知道是否能传上图片). the characterization factor, cf, also called the uop or watson characterization factor, uop k, is defined as the cube root of the boiling point of a compound (in degrees rankine) divided by the specific gravity, sg, of the liquid at 60 f (referred to water at 60 f). cf=uop k=(tb+459.67)^(1/3)/sg(@60 f)/60 f. where tb=normal boiling point, f. the uop k or characterization factor should not be confused with the k factor used in vapor/liquid equilibrium calculations. the two k's are completely different.查看更多
