More Information
Summary:The present invention is a method for purifying ammonia and an ammonia purification system whereby impurities in crude ammonia can be efficiently adsorbed and removed and whereby ammonia can be purified by a simplified method. In an ammonia purification system (100), a first adsorption tower (21) and a second adsorption tower (22) adsorb and remove impurities in crude ammonia, using an adsorption agent having the ability to adsorb moisture and hydrocarbons only. A first condenser (31) partially condenses the ammonia from which the impurities have been adsorbed and removed, to thereby separate out and remove highly volatile impurities as gas phase components.
