ADSORPTION/DESORPTION AGENT, PROCESS FOR SEPARATION, AND STORAGE METHOD FOR AMMONIA USING COMBINATION OF SPECIFIC METAL HALIDES

摘要

PROBLEM TO BE SOLVED: To provide an ammonia separation method capable of easily and efficiently separating even ammonoia synthesized on-site using an absorption/separation method such as PSA or PTSA and further capable of storing.

SOLUTION: The method for separating ammonia using metal halides, is characterized in that: ammonia-containing gases are brought into contact with a mixture of calcium chloride and calcium bromide under a pressure permitting adsorption of ammonia to adsorbe ammonia; and, the pressure is reduced to separate ammonia. The apparatus therefor is also disclosed.
