Treatment of gases with adsorbent solids
TLDR
In this article, the authors describe a method for the selective removal of certain gases or vapours from a mixture of gases by passing the gases through adsorbent solids such as active charcoal or silica gel.Abstract:
This invention is for improvements in or relating to the treatment of gases with adsorbent solids and has particular reference to the selective removal of certain gases or vapours from a mixture of gases by passing the gases through adsorbent solids such as active charcoal or silica gel.

Process and apparatus for recovering hydrocarbons from air-hydrocarbon vapor mixtures
Harold L. Dinsmore,Jon W. Young +1 more
TL;DR: In this paper, a pair of alternatively used carbon bed adsorbers are used to remove hydrocarbon vapors from the mixture and which are desorbed of hydrocarbons by subjecting the beds alternatively to vacuum regeneration using a vacuum pump the output of which is passed through an absorber using liquid gasoline as the absorbent liquid.

Process and apparatus for recovering hydrocarbons from air-hydrocarbon vapour mixtures
TL;DR: In this paper, a process and apparatus for recovering hydrocarbons from an air-hydrocarbon vapour mixture is described, where the first bed (12, 14) of solid adsorbent is removed from the mixture and a residue gas stream by substantially hydrocarbon-free air is vented to atmosphere and a second bed (14, 12) of the same mixture is desorbed by applying vaccum thereto using a liquid seal vacuum pump (72).
