Which of the following factors affect the pressure drop in a co-current gas-liquid absorption packed tower ?
Correct answer: C. All A., B. and C.
- A. Size, shape, orientation and surface of the packing particles
- B. Density and viscosity of fluids
- C. All A., B. and C.
- D. Fluid flow rates
Explanation
Packed-tower pressure drop depends on packing geometry and surface, fluid density and viscosity, and gas-liquid flow rates. Therefore, all three groups of factors affect the pressure drop.
