摘要: A process for enriching a crude ammonia stream having moisture and/or metal impurities and/or gas impurities therein. The crude ammonia stream is condensed to form a crude liquid ammonia stream. A distillation membrane or pervaporation membrane is contacted with the crude liquid ammonia stream to form an enriched ammonia vapor stream, which is removed as a permeate. When the crude ammonia stream originates from a manufacturing tool, the enriched ammonia vapor stream may be recycled to the manufacturing tool. There is also an apparatus for enriching a crude ammonia stream.
