Résumé

From the Danckwerts theoretical surface renewal model of mass transfer, an approach using nanoparticles to enhance ammonia bubble absorption process was examined in this study. In the experiment, the ammonia vapour flow flux and the concentration ratio of bulk ammonia solution were adjusted and their effects on ammonia bubble absorption were explored. The experimental results show that the absorption ratio was significantly increased by adding Al(2)O(3) nanoparticles in the bulk solution, and the effective absorption ratio could reach 1.22 times that without Al(2)O(3) nanoparticles in the bulk solution. In addition, the increase in the concentration ratio of ammonia solution enhanced the effective absorption ratio clearly while the variation of the ammonia vapour flow flux did not exhibit consistent positive influence on absorption process.
