Abstract
Acidic halogens, especially chlorides, are removed from a dry gas stream by contact with dry particles of solid caustic. The solid caustic particles are preferably non-porous, and disposed in a bed with at least a 10% bed interstitial volume. Limiting halogen content in gas, and operating with a bone dry gas, ensures that salts deposit on the surface of the solid caustic without plugging the bed of solid caustic. Efficient halogen removal can be achieved even when treating a bone dry gas, one having less than 10 ppmv water vapor, at ambient temperature, without plugging the bed.
