Abstract

A method of monitoring CaCO~3~ production from absorption of CO~2~ into an aqueous solution of Ca(OH)~2~ is described. Its application to the measurement of Ca(OH)~2~ conversion across different radial zones on a spinning disc reactor is discussed and results from experiments are presented. Links between conversion and models based on diffusive mass transfer into a thin rotating film are examined and a correlation with Fourier and Reynolds numbers shown. Estimations of mass‐transfer coefficients based on the experimental results are provided and comparisons made with previous work. © 2005 American Institute of Chemical Engineers AIChE J, 2005
