Abstract

In a solvent recovery process by adsorption of solvent from the gaseous or vapour phase wherein steam is used for stripping the solvent from the adsorbing material and at least two adsorbers are being steamed at any given time in the operation cycle, the method of steaming the two or more adsorbers comprises passing the steam through the adsorbers in series so that for part of its steaming time each adsorber is receiving the solvent-carrying steam coming from another adsorber and for a later part of its steaming time it is receiving fresh steam. There is reference to recovery of acetone or methylene chloride or ethyl alcohol from air by adsorption on to carbon.
