The Diffusional Removal of Adsorbed and Absorbed Gasses from Solid Surfaces

The removal and eventual disposal of adsorbed and absorbed gasses from solid or semi-porous surfaces requires the detachment and diffusion of the gasses. To facilitate the process, the method described here uses the heretofore undescribed product Air Depleted Water (ADW), although the process can be applied to other liquids. By removing the dissolved air gasses, a maximum concentration gradient for diffusion is established. Further, the ADW provides an excellent vehicle for dissolving, carrying, and eventually disposing of the gasses. The paper provides a background for diffusion as a commercial process and an introduction to the obscure area of solubility of gasses in liquids. Several applications are discussed briefly for illustration of the method.
