<p>A method for drying wet industrial gases by contacting them with a refrigerated inorganic brine is shown. The wet gas is contacted with cold brine and water vapor is condensed from the gas into the brine. In a preferred method, two stages of gas-liquid contact are employed to produce a particularly dry gas product. Brine used in the first contacting zone is heat exchanged with colder brine used in the second contacting zone; and, if desired, it may be heat exchanged with dry cold gas product from the second zone before recycle to the first zone. Brine from the second zone is subjected to refrigeration before recycle to the second zone. Drying is carried out in conventional packed towers, at low pressure, and does not require system regeneration or replacement of expensive adsorbents.</p> |
