Abstract
AbstractWell‐designed absorption columns are indispensable to industry. A prototypical system is the absorption of gaseous NH3. This experiment employed the method of transfer units where collection of vapor (V) and liquid (L) flow rates and concentrations enabled the characterization of the number of transfer units (NTU), height of transfer unit (HTU), and overall gas phase mass transfer coefficient (Ky). A nonmonotonic relationship between V, L, NTU, and HTU values was found; Ky showed a monotonic relationship with V and L. Computer‐simulated, correlation‐based, and experimental NTU, HTU, and Ky values demonstrated close numerical similarities. This experiment highlighted the importance of a combined empirical, theoretical, and simulation approach in achieving more reliable results from absorption column analysis.
