aspen中的k值是什么意思,怎么应用? 对液相,将k值理解为“分配系数”就好理解了。组分a,第二液相对第一液相的k值,即相平衡下,第二液相中的a与第一液相中的a组分的摩尔比。 k-value the ratio of the amounts (in terms of mole fractions or partial pressures) of the same component in two phases in equilibrium . k-values can be calculated for vapor-liquid equilibrium and liquid-liquid equilibrium . in vapor-liquid-liquid equilibrium, different k-values can be calculated for any two of the three phases.查看更多
