Absorption in a three-phase fluidized bed II: Mass transfer investigations
Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
Abstract
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration change in the liquid phase on-line by a conductivity probe. It was shown that the Danckwerts plot method might be successfully used to simultaneously determine the effective interfacial area and both the gas and liquid-side mass transfer coefficients. While the gas-side mass transfer coefficient is independent of the liquid flow rate, the effective interfacial area and liquid-side mass transfer coefficient increase with increasing liquid flow rate.

Korišćenjem metode Danckwerts-ove zavisnosti, dobijene su vrednosti efektivne međufazne površine kontakta po jedinici zapremine statičkog sloja punjenja i koeficijenata prelaza mase ugljendioksida sa strane gasa i sa strane tečnosti u funkciji protoka tečnosti.
