Mass transfer from gas bubbles in an agitated vessel with and without simultaneous chemical reaction

摘要: Abstract A simplified model is proposed that permits the prediction of total mass transfer rates for a sparingly soluble gas in gas-liquid contactor. The based on average residence time bubbles continuous phase, and estimation rate diffusion per unit area as well diffusion. knowledge bubble diameter, reaction constant, diffusivity contactor operating conditions necessary to arrive at numerical solution equations. equations have been solved large range variables results are presented graphically. predicts correctly effect changes diffusivity, liquid flow rates, diameter agitation intensity rates.
