Abstract
This paper presents a numerical method based on the Zivi-Brand method applied to cross-flow cooling towers and an analytical solution based on the Nusselt solution of heat exchangers for the estimation of the concentration of solute in cross-flow absorption towers. Experimental apparatus used in this work are a wetted-wall tower and a rod-like irrigation tower.
The experimental data for concentration distribution has been obtained for absorption of ammonia in city water in these towers. The results were in good agreement with results calculated by the solution described above. Therefore, these calculation methods are available for the estimation of solute concentration in cross-flow absorption towers.
