Popis: | A model describing the fouling in irrigated columns with random packings was applied successfully to the description of the increase in pressure drop when fouling occurs during the absorption of CO 2 in a suspension of Ca(OH) 2 . It is based on the Darcy-Weisbach law and the channel model. A mass balance around a fouling layer on the packings leads to a time-dependent equation including the hydraulic radius from the channel model. A removal term is introduced in the fouling model. To approach the experimental results, the removal term had to be extended by an empirical parameter. It can be interpreted as a removal efficiency factor and is obtained by easy numerical fitting. |
