Gas Hold‐Up in Stirred Tank Reactors in the Presence of Inorganic Electrolytes

Year: 2002

Type: article

Abstract: Gas hold‐up (ϵG) in air‐aqueous electrolyte solutions in stirred tank reactors (STR) is correlated using a relative gas dispersion parameter, N/Ncd and a surface tension factor (STF), (c/z)(dδ/dc)2. For electrolyte concentration below transition concentration (ct) a single correlation in the form of ϵG = f(N/Ncd, vvm, STF) shows good agreement with gas hold‐up data over a wide range of system and operating conditions. Above ct no effect of STF on gas hold‐up is observed and the correlation obtained is of the form ϵG = f(N/Ncd, vvm). Data available in the literature on large STR show good fit with the proposed correlation.
