EVALUATION OF GAS PHASE MASS TRANSFER AT LOW REYNOLDS NUMBERS: A NEW MODEL SYSTEM

Abstract

A new experimental system is presented which is suitable for studying gas side mass transfer coefficients in packed columns at Reynolds numbers even lower than 1·0. The system involves desorption of iodine from aqueous KI solutions. The reversible complex formation between iodine and iodine ions effectively slows down the concentration changes which otherwise would be too rapid for accurate experimentation.

KEYWORDS:

• Mass transfer
• iodine absorption
• static hold-up
• packed column
• absorption with reaction
• low Reynolds number
