Yara Pilbara – Ammonia Reformer Steam Coil, Hot Process Air Coil and Piping Life Extension Solutions

During a regular planned shutdown the client noticed distortions in the steam coils and displacement of coil headers. At high temperatures and pressures the coils were subjected to creep and fatigue. Metallurgical and NDT inspections done by Yara showed the remaining life of steam coils have reduced than original design life but still good to go for some years. Sustech was engaged by Yara to find the reason of the damage and suggest means of improvement to slow down the reduction. We did a site visit with the client’s maintenance engineer to do the initial visual assessment of the coil and header condition. We understood that the internal coil design of the reformer is not being able to withstand   the piping loads from the reformer external piping. We did pipe stress analysis of the coil connected steam piping to find solutions to ease the loads on the coil header. The high stress levels and distortions in the coils were reducing the remaining life. The solution was restricted to no piping layout change as that would delay the start up and result in huge loss of production and revenue. So we focussed on the support modifications and releasing loads on the steam header. We designed new supports and selected new springs modified existing supports and provided solutions to stop accelerated remaining life reduction of the steam coils and headers. We did similar exercise for Hot process air in the same ammonia reformer. Lines are connected to secondary reformers also.

 

OGDCL -Fired Heater Tubes Fitness for Service Assessment – Mechanical analysis for fired heater tubes and advise on safety of equipment and start up

Sustech did API579 Fitness for service assessment calculations and API 530 calculations and looked at other NDT test results to advise OGDCL for a safe start up but under a constant monitoring regime of fitness for service. This enabled OGDCL to come out of the shutdown without major delay and loss of production.

 

Yara Pilbara – Steam Turbine Shaft Misalignment Solution

During regular operation, the back-pressure steam turbine was tripping occasionally due to shaft misalignment. Further observations revealed that the turbine exhaust nozzle flange was having uplift and parallelity issues. The root cause was assessed to be the turbine exhaust steam piping configuration. The piping during the operating condition was pushing the exhaust nozzle up and tilting it, thus creating the turbine shaft misalignment. We did the pipe stress analysis of the line to simulate the situation and understand the problem. The layout was stiff and not qualifying the NEMA SM23 allowable loads at the exhaust nozzle. We provided a total solution with in line pressure balance expansion bellows to qualify the loads. But as the start up of the turbine was due in short time, so we had to come up with an in-service solution which could be implemented while in operation. We changed springs and modified supporting arrangements to provide for solutions to stop turbine flange lifting and tilting and stopped it from tripping.

 

Yara Pilbara – Synthetic Gas Piping Stress Analysis and Support Spring Replacement

The synthetic gas piping from gas heater to the ammonia converter had issues of non-functioning spring, cumbersome operating procedure of shimming rest supports at the start up, and high loads at equipment nozzles.
