【Daily Question】Chemical Engineering Principles 579: Absorption Rate in Packed Columns (June 29)
Thread Content
This post was last edited by Zaihui Kangqiao on 2017-6-29 07:53. The Chemical Engineering Theory section is launching a \"One Question per Day\" activity starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series such as \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" will also be introduced. We hope for your active support~~~ Replies to the \"One Question per Day\" activity can be viewed directly; the thread will be closed after 1 day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ True or False: A large amount of packing is used in a packed tower to provide a surface area for gas-liquid contact. The absorption rate depends on the specific surface area of the filler (a). The greater the specific surface area of the filler, the higher the absorption rate. ( ) Wrong
That can’t be right. The absorption efficiency is proportional to the specific surface area of the filler. The absorption rate depends on the driving force for absorption; for gas film control, it is related to the initial vapor pressure and the final vapor pressure.
