<P>PROBLEM TO BE SOLVED: To provide an ammonia purifying system capable of purifying ammonia by a simplified method and efficiently purifying ammonia while suppressing energy consumption. <P>SOLUTION: The ammonia purifying system 100 is a system for purifying crude ammonia and includes a vaporizer 2, an adsorbing means 3 and a condenser 5. The vaporizer 2 evaporates a part of liquid crude ammonia and discharges gaseous ammonia. The adsorbing means 3 adsorbs and removes low-volatile impurities in the gaseous ammonia discharged from the vaporizer 2 with a porous adsorbent. The condenser 5 separates the gaseous ammonia discharged from the adsorbing means 3 into a gas-phase component and liquid-phase component by partial condensation, thereby separating and removing highly volatile impurities as a gas-phase component to obtain purified liquid ammonia as the liquid-phase component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
