Gas - Liquid Contacting
Gas-liquid contacting or sparging applications involve flowing gas through a fine grade, porous material with fine uniform pores to produce small bubbles that result in high efficiency contact between a gas and a liquid. Normally, 2 or 10 micron grade materials are used to prevent the liquid from penetrating back into the pores at lower internal pressures. Porous metal spargers are excellent replacements for drilled holes that produce larger bubbles and do not dissolve and react as well as the finer bubbles generated by porous metals. Spargers or Aerators are used to agitate liquids, to improve oxygen levels for fish farming or to improve heat transfer. Other chemical processes such as hydrogenation, bioremediation, fermentation, and pH control use fine bubblers to enhance chemical reactions. Porous sintered metal carbonators are also widely used in the beverage industry.
