Many chemical engineering processes are based on the absorption or desorption of gaseous material into a liquid phase. During glass melting, bubbles are created due to chemical reactions between raw materials and undergo, further, mass transfer due to fining process enhancing the rate of bubbles removal. The main purpose of our work is to provide a comprehensive understanding of the interplay between diffusion, advection and chemical reaction during mass transfer across the bubble interface. More precisely, we focus on the determination of the enhancement factor due to the chemical reaction on the rate of mass transfer.
