PURIFICATION METHOD OF HIGH PURITY AMMONIA

摘要

The present invention relates to a purification method for ammonia which produces high purity ammonia by purifying impurities contained in raw ammonia. The purification method efficiently and simultaneously removes moisture which is impurities contained in raw ammonia, volatile organic compounds (VOCs), carbon dioxide, carbon monoxide, and oxygen by using a purification tower consisting of a synthetic zeolite layer, an activated carbon layer, an alkali layer, a catalyst layer including copper oxide (CuO), and manganese dioxide (MnO_2) and is able to simplify a continuous purification process.
