【Daily Question】Chemical Engineering Principles 121: Distillation (July 26)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" – we hope you will give it your active support! Answers can be viewed directly by replying to the \"One Question per Day\" posts, and these posts will be closed after 1 day ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ For fill-in-the-blank questions: A distillation column heated directly by steam is suitable for ___________________. Compared to indirect steam heating, the number of theoretical plates required under the same conditions will be ____________. The mixture to be separated is an aqueous solution, with water being the poorly volatile component. The number of theoretical plates should be high.
A distillation column heated directly by steam is suitable for separating light-component solutions; compared to indirect steam heating, the number of theoretical plates required increases under the same conditions.
A distillation column heated directly by steam is suitable for (separating light-component aqueous solutions); compared to indirect steam heating, the number of theoretical plates required under the same conditions will be (higher).

The mixture to be separated is an aqueous solution, and in many cases water is the component that is difficult to volatilize.
The mixture to be separated is an aqueous solution, with water being the poorly volatile component. The number of theoretical plates should be high.
When the mixture to be separated is an aqueous solution and water is the component that is difficult to volatilize, a larger number of theoretical plates is required
Answer: (In the case where the mixture to be separated is an aqueous solution and water is the poorly volatile component), (the number of theoretical plates needs to be high).
