The value of „L/mG' ratio for economical absorption operation ranges from _____________________?
Correct answer: C. 1.25 to 2.0
- A. 0.5 to 0.8
- B. 0.8 to 1.2
- C. 1.25 to 2.0
- D. 2.5 to 3.5
Explanation
For economical absorption, the liquid-to-gas flow ratio relative to the equilibrium-line slope, L/mG, is commonly maintained around 1.25 to 2.0. A lower ratio gives inadequate absorption driving force, while a much higher ratio increases solvent-circulation cost.
