A large U.S. fertilizer manufacturer that was experiencing a “hot spot” on the external steel shell where a manway used to exist.
No emergency shut down needed to perform conventional repairs.
This fertilizer plant’s products include anhydrous ammonia, urea, urea blends, ammonium nitrate solution, phosphate, potash, ammonium polyphosphate, and sulfur-based products.
The ammonia reformer within the plant was experiencing a “hot spot” on the external steel shell where a manway used to exist. The plant personnel attempted to repair this area on their own by installing a steel box over the affected area and filling it with castable refractory. This repair approach only survived for two weeks. Seeking a more permanent solution that would help them avoid an emergency shutdown, they contacted IGS (Integrated Global Services) for a solution.
HRR (Hot Refractory Repair) service effectively replaces missing refractory without shutdown. The project was successfully completed in three days without any issues or impact on production.
During the application, another hot spot was identified in the surrounding area and was also repaired.
The plant manager was extremely happy with the results and no longer needing to consider an emergency shut down to perform conventional repairs.
Hot spots resulting from damaged refractory, scaled or misaligned process tubes, plugged SCR catalyst banks, and fouled convection sections can all affect the performance, reliability and safe operation and ultimately the operating capacity of the fired heater.
If a planned shutdown is still years away, Maintenance Managers are faced with a dilemma. To accept the risks and inferior performance or attempt temporary repairs, potentially still risking an unplanned shutdown if the solution is not fit-for-purpose.
Refineries, Petrochemical and Agrochemical Plants rely on the Hot-tek service, delivered by Integrated Global Services (IGS) to effectively address fired heater maintenance challenges in between turnarounds, without the need to shut down or power down their fired heaters.
Each service has been designed and perfected in collaboration with major oil and gas refineries to ensure that the safety, performance, and the output of the fired heater is not compromised.
