SAFCO operates the first single train 3300 MTPD Ammonia plant in the world. In January 2012, an increase in pressure drop was noted at the first synthesis loop boiler downstream the first ammonia converter. After a plant trip, the outlet temperature of this boiler increased without noted influence on the steam production of the boiler. The outlet temperature and pressure drop partly recovered after a power outage. During the turnaround in April 2012, an inspection of the boilers was carried out. It was discovered that the experienced changes of operation in the boiler were related to a material damage in the upstream ammonia converter. The damage resulted in an extensive repair performed with available site personnel.
