Contact elements, for use in a mobile bed scrubber, comprised of polymeric resinous materials with a specific density range, a specific compressive strength range, and other specific physical properties are disclosed, which, when used in such a mobile bed scrubber in a continuously moving bed have a useful life of greater than 8,000 hours, based upon an acceptable decrease in surface area of about 45%. Such a useful life is far greater than the useful life of similar contact elements not having the above mentioned physical properties within the desired ranges recited. |
