Abstract
The present invention relates to an improved adsorption process for recovery of a condensible organic contaminant from a humid gas carrier stream. The improvement in such process comprises the steps of passing the humid contaminant-laden gas through a first adsorber until the organic contaminant is detected at a preset 'breakthrough' level in the outlet gas. The outlet gas from the first adsorber is then passed through a second adsorber until the level of organic contaminant is determined to be at approximately the level of organic contaminant in the humid contaminant-laden gas being passed into the first adsorber, and at which point part of the less well-adsorbed water has passed into the outlet gas of the first adsorber. At such time, passage of the humid contaminant-laden gas into the first adsorber is discontinued and, instead, the humid contaminant-laden gas is passed into the second adsorber. During passage of the humid contaminant-laden gas into the second adsorber, the first adsorber, now loaded only with organic contaminant is regenerated. The humid contaminant-laden gas is passed into the second adsorber until the contaminant in the outlet gas from the second adsorber reaches the breakthrough level, at which time the process may be continued by passing the outlet gas from the second bed into the regenerated first bed.
