【Daily Question】Chemical Engineering Principles 127: Recirculation (August 1)
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 to the questions in the \"One Question per Day\" campaign can be viewed directly by replying, and the thread will be closed after 1 day ! You get 2 wealth points for participating, and an additional 3 wealth points for correct answers~~~ True or False: When the reflux ratio is constant, the higher the temperature of the liquid returning to the top of the tower, the better the separation effect. Wrong
Error. ---------------------------
When the reflux ratio is constant, the higher the temperature of the liquid returning to the top of the tower, the better the separation effect. CHUO
Analysis: When the reflux ratio and the number of theoretical plates remain constant, the lower the temperature of the reflux liquid, the greater the actual amount of material circulation within the tower, which results in improved separation efficiency. However, this comes at the cost of increased energy consumption in the bottom of the tower
When the reflux ratio is the same, the higher the temperature of the liquid returning to the top of the tower, the better the separation efficiency. False
When the reflux ratio is constant, the higher the temperature of the liquid returning to the top of the tower, the better the separation effect. Wrong
Wrong; the lower the reflux temperature, the better the separation effect
When the reflux ratio is constant, the higher the temperature of the liquid returning to the top of the tower, the better the separation effect. (×)
When the reflux ratio is constant, the higher the temperature of the liquid returning to the top of the tower, the better the separation effect. (×)
