Fixed bed adsorption

  1. Apr 6, 2008 #1
    Air is compressed to 10 atmospheres, cooled to 25 degrees C and passed through a bed of molecular sieve that has an initial moisture content of 8 lb water/100 lb sieve. the saturation vapor pressure of water at 25C is 24 mmHg. Assume M.W of air is 30 and the height of a transfer unit is 3 inches. How can i calculate the inlet and outlet gas relative humidities?

    You should use Fick's first laws and set up some mass balance for the mass transfer. Take the following source for some caluclated examples: http://www.composite-agency.com" [Broken]. Regards, Hedenqvist
