Ammonia production

Ammonia is a key material for the production of fertilizers. Its synthesis involves a multi-step process to provide hydrogen which is converted to ammonia under extreme pressure. The high reaction speed and the high material throughput require tight process control at each step. Continuous gas analyzers can monitor H2, CH4, CO, CO2, and NH3 and offer a great advantage to gas chromatographs due to their fast response time. Because of catalyst poison-ing and salt-formation, CO and CO2 need to be detected at very low ppm levels.
