【Daily Question】Chemical Engineering Principles 433: Fixed Bed Regeneration (September 21)
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! Wishing you a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! You get 3 wealth points for participating, and an additional 4 wealth points for answering correctly~~~ Short answer question: What is the purpose of adding water under pressure during the regeneration of a counter-current fixed-bed reactor? Prevent disorderly layering
What is the purpose of adding water to apply pressure during the regeneration of a counterflow regenerative fixed-bed? Prevent disorderly layering
The counter-current bed operates in a co-current manner (during operation, water flows from top to bottom into the resin layer to carry out ion exchange), and in a counter-current regeneration manner (during regeneration, the regeneration liquid flows from the bottom of the bed and passes through the resin layer from bottom to top for regeneration).
