Absorption (liquid-gas system) with evolution of heat as compared to isothermal absorption results in_________________?
Correct answer: D. All A., B. and C.
- A. Decreased solute solubility
- B. Large minimum liquid to gas (L/G) ratio
- C. Large number of trays
- D. All A., B. and C.
Explanation
Heat evolution raises the liquid temperature and usually lowers solute solubility, reducing the absorption driving force. The absorber consequently needs a larger minimum L/G ratio and generally more trays, so all three statements apply.
