Mass transfer in a multiple stage cross-current packed column

Creator:

Bayan, Ghawamedin

Abstract:

A cascade crosscurrent column, packed with Pall rings, was employed for ammonia absorption from ammonia-rich air phase by contacting with water. Absorption efficiency was presented as the percentage of NH₃ removed as well as the volume of a transfer unit. A review of the literature concerning the theoretical and experimental...

Gas absorption in a countercurrent packed tower : (1) Absorption with simultaneous chemical reaction (2) absorption into varying viscous solutions

Creator:

Cho, Jong Soo

Abstract:

The surface renewal rate from Danckwerts' theory and the effective interfacial area between gas and liquid per unit packing volume in a packed absorption tower were evaluated for the absorption of carbon dioxide into carbonate/bicarbonate buffer solution accompanied by a pseudo-first order chemical reaction. The rate of chemical reaction in...
