Thread Content
This post was last edited by “Back to Cambridge” on September 22, 2015, at 10:51. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, a series of topics such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active participation! For the “Question of the Day” activity, answers can be viewed directly in the replies; however, the thread will be closed after one day! ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ Fill-in-the-blank: The basis for distillation separation is the difference in ________, and to completely separate the components in a mixture, it is necessary to carry out multiple ________s. ________. Vapor pressure of each component, partial vaporization and partial condensation
Vapor pressure of each component； Partial vaporization and partial condensation.
Vapor pressure of various components, vaporization, condensation
1. Boiling point. 2. Vaporization, condensation.
The basis for distillation separation is the difference in the _volatility of various components_. To achieve complete separation of the components in a mixture, multiple cycles of _partial vaporization and partial condensation_ are necessary.
Vapor pressure of each component: partial vaporization, partial condensation
Vapor pressure of each component, partial vaporization, partial condensation
The basis for distillation separation is the difference in __boiling points__. To completely separate the components in a mixture, it is necessary to carry out multiple rounds of __vaporization_____ and __condensation__.
The basis for distillation separation is the difference in volatility of various components; to achieve complete separation of the components in a mixture, it is necessary to carry out multiple instances of partial vaporization and partial condensation.
Distillation separation is based on the differences in the volatility of various components; to achieve complete separation of the components in a mixture, multiple cycles of partial vaporization and partial condensation are necessary.
Distillation separation is based on the difference in relative volatility between components; to achieve complete separation of the components in a mixture, multiple cycles of vaporization and condensation are necessary
