【Daily Question】Chemical Engineering Principles 546: Absorbents (April 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 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 for your active support~~~ Replies to the \"One Question per Day\" campaign can be viewed directly at **; the topic will be closed after 1 day! ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: The 4 main factors to consider when choosing an absorbent are ___________, ___________, ___________, ____________. 7. Solubility ； selectivity ； Volatility ； viscosity
(Solubility)(Selectivity)(Volatility)(Viscosity
Volatility, selectivity, viscosity, solubility
Solubility, selectivity; volatility; viscosity
1. The absorbent must have good absorption properties; this is the most important requirement. 2. It should also possess good selectivity, enabling it to absorb only the substances required. 3. The absorbent should have low volatility, as this helps to reduce losses of the absorbent, lower operational costs, and protect the environment. Additionally, the chosen absorbent should be able to be easily separated from the solute during subsequent separation processes. 4. Ideally, the absorbent should be non-toxic and harmless. With the current emphasis on environmental protection, this ensures both environmental sustainability and reduced processing costs
