Vacuum degasification of water

Abstract

A procedure for design of a water vacuum degasifier is presented for removing oxygen, carbon dioxide, nitrogen, and argon from water from‘35 to 90 F. This procedure is based on gas solubilities following Henry’s law and diffusivities fol­ lowing the Stokes-Einstein equation. Column mass transfer is described in terms of the number and height of overall liquid transfer units, Nₒₗ and Hₒₗ. A computer performance program is presented.
