同时,初始混合物中含有较多不易挥发组分。
At the same time, the original mixture will contain more of the less volatile material.
该蒸气含有更多易挥发组分,并沿塔向上层塔板上升。
This vapour, which moves up to the next tray in the column, is richer in the more volatile components.
因此,当该蒸汽被冷凝时,冷凝液中含有较多易挥发组分。
Therefore, when this vapour is cooled and condensed, the condensate will contain more volatile components.
