AMMONIA PURIFICATION SYSTEM AND METHOD FOR PURIFYING AMMONIA

摘要

The present invention provides an ammonia purification system capable of purifying ammonia in a simplified method and of effectively purifying ammonia by reducing energy consumption. The ammonia purification system (100) includes an oil adsorption tower (2), a high boiling impurities adsorption unit (3) and a vaporizer (5). The oil adsorption tower (2) adsorbs and removes oil contained in liquid crude ammonia by activated carbon. The high boiling impurities adsorption unit (3) adsorbs and removes high boiling impurities contained in the liquid ammonia by synthetic zeolite. The vaporizer (5) vaporizes the liquid ammonia delivered from the high boiling impurities adsorption unit (3) at a predetermined vaporization rate, and separates and removes low boiling impurities as a gaseous phase component.
