【Daily Question】Chemical Engineering Principles 130: Absorption Rate (August 4)
Thread Content
This post was last edited by “Back to Cambridge” on August 4, 2015, at 11:41. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will also 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~~~ Multiple-choice question: In an absorption tower under normal operating conditions, if only the concentration of the absorbent fed into the tower is reduced, then the absorption rate will ( ) ； Again, when clean water is used as the absorbent, and all other operating conditions remain unchanged while only the concentration of the gas entering the tower is reduced, the absorption rate will ( ). A. Increase ； B. Reduce ； C, unchanged ； D、Uncertain ； AC
In an operating absorption tower, when all other operating conditions remain unchanged and only the concentration of the absorbent fed into the tower is reduced, the absorption rate will (B) decrease； Again, when clean water is used as the absorbent, and all other operating conditions remain unchanged while only the concentration of the gas entering the tower is reduced, the absorption rate will (A) increase.
In an operating absorption tower, when all other operating conditions remain unchanged and only the concentration of the absorbent fed into the tower is reduced, the absorption rate will ( a )； Again, when clean water is used as the absorbent, and all other operating conditions remain unchanged while only the concentration of the gas entering the tower is reduced, the absorption rate will (b).
1. A 2. D depends on the material properties of the feed
A. Increase； C, unchanged ；
Answer: B, Reduce； A. Increase ； :handshake
A. Increase； C, unchanged ；
In an operating absorption tower, when all other operating conditions remain unchanged and only the concentration of the absorbent fed into the tower is reduced, the absorption rate will (increase)； Again, when clean water is used as the absorbent, and all other operating conditions remain unchanged while only the concentration of the gas entering the tower is reduced, the absorption rate will (remain unchanged).
In an operating absorption tower, when all other operating conditions remain unchanged and only the concentration of the absorbent fed into the tower is reduced, the absorption rate will ( A )； Again, when clean water is used as the absorbent, and all other operating conditions remain unchanged while only the concentration of the gas entering the tower is reduced, the absorption rate will (C).
