- For the treatment of an air-based off-gas stream, the use of packed beds of Ba(OH)/sub 2/.8H/sub 2/O flakes to remove CO/sub 2/ has been demonstrated. However, the operating conditions must be maintained between certain upper and lower limits with respect to the partial pressure of water. If the water vapor pressure in the gas is less than the dissociation vapor pressure of Ba(OH)/sub 2/.8H/sub 2/O, the bed will deactivate. If the vapor pressure is considerably greater, pressure drop problems will increase with increaseing humidity as the particles curl and degrade. Results have indicted that when operated in the proper regime, the bulk of the increase in pressure drop results from the conversion of Ba(OH)/sub 2/.8H/sub 2/O to BaCO/sub 3/ and not from the hydration of the commercial Ba(OH)/sub 2/.8H/sub 2/O (i.e., Ba(OH)/sub 2/.7.50H/sub 2/O) to Ba(OH)/sub 2/.8H/sub 2/O.
