Chlorine Fluxing

Problem Description

Chlorine gas is injected through a rotating impeller to react with unwanted metals in the molten aluminum and forms a layer that floats on the top.

Challenge

Minimize the amount of chlorine gas escaping:

  • Escaped gas reacts with ambient air and forms harmful hydrochloric acid emissions
  • Cut down the running cost of chlorine gas consumption

Benefit of Modeling

  • Explore different designs to increase the residence time of chorine bubbles and hence reduce the cost of chorine consumption and reduce health risks
  • Coupling of chemical reaction kinetics with the flow analysis would result in obtaining the optimum chorine bubble size from both the a chemical and a hydrodynamic point of view
