Abstract:
An element of the type adapted to be inserted in a rotary regenerative heat exchanger, such heat exchanger having a gas flow containing ammonia directed thereto on one side thereof, comprising:an adsorbent media on at least partial surfaces of such element; said adsorbent media a composition that will adsorb ammonia within a preselected temperature range and ammonia concentration in the gas flow on such one side of such heat exchange, which is within the operational temperature range and ammonia concentration range on such one side, and will desorb such adsorbed ammonia on the side opposite such one side, in response to the temperature and ammonia concentration in a gas flow on such opposite side; and during such adsorption and desorption, said adsorbent media will be substantially inactive as a catalyst with respect to the constituents in the gas flow passing thereby.
