Abstract

In a method of operating an adsorber installation having at least two, e.g. three, adsorbers 10, 11, 12 each comprising a vessel divided into two chambers by a regeneratable adsorbent bed for stripping solvent from solvent-laden air, steam is passed through the bed of an adsorber taken out of adsorbing service to remove adsorbed solvent by steam distillation and, during at least part of the steaming, the steam distillate therefrom is passed through a second adsorber taken out of adsorbing service to commence steaming thereof before cooling the distillate and recovering solvent. Series adsorbing and series steaming can be effected in a combined manner in a continuous operational cycle, the series adsorbing being effected using air recycle duct 41 and the series steaming being effected using steam recycle duct 33 connected to a primary distillate duct 29, a secondary distillate duct 37 also being provided for removal of recycled steam. <IMAGE>
