【Daily Question】Chemical Engineering Principles 132: Distillation Columns (August 6)
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 in 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 for your active support! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 day ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ Multiple-choice question: In a vacuum-operated distillation column, if the vacuum level decreases while F, D, R, q, and the feeding position remain unchanged, what will be the change in the composition of the product at the top of the column? A. Become smaller ； B、Grow larger ； C、Unchanged ； D、Uncertain ； A

In a vacuum-operated distillation column, if the vacuum level decreases while F, D, R, q, and the feeding position remain unchanged, the composition of the product at the top of the column will change ( ). A. Become smaller ； B、Grow larger ； C、Unchanged ； D、Uncertain ； A
The answer to this question is: A, become smaller；
In a vacuum-operated distillation column, if the vacuum level decreases while F, D, R, q, and the feed position remain unchanged, the composition of the product at the top of the column changes to (A: become smaller).
