Abstract
A method is disclosed herein for recovering a vaporous material from a continuous gas stream. Two charcoal filter assemblies are mounted for raising into a passageway defined by a chamber. The charcoal filters may alternately be lowered from the passageway and into a container for regeneration. The container is filled with water which is then heated to vaporize an azeotrope of the water and the material adsorbed by the charcoal. The water is then drained from the container, and the filter is returned to its position within the passageway.
