How to prevent corrosion in decommissioned sulfur plants
Thread Content
The company’s new sulfur processing unit has come online, which means the old unit must be shut down. However, it is necessary to protect the equipment located in the old unit’s area from corrosion and damage, so that they can remain ready for use at any time. We invite all colleagues to share their ideas and work together to find solutions.
We once used continuous nitrogen supply, but we had no idea about how much to supply.
Is it the normal process from the sulfur production furnace to the chimney? What about that liquid sulfur tank? Empty the liquid sulfur? Is the heat tracing still being supplied?

It’s uncertain; depending on the performance of the new device, it will probably be one or two years
After the device is emptied, a protective agent for standby use is added, ensuring safety and efficiency while saving time and effort. Lanzhou Huarong Cleaning and Anti-corrosion Engineering Co., Ltd. provides this technical service; contact number: 13309317532
The answer above is correct – fill it with nitrogen. As for the liquid sulfur tank, if it isn’t used for a long time, it’s still worth taking the time to clean it as much as possible
Here, the Claus furnace, hydrogenation furnace, and tail furnace are all protected by filling them with low-pressure nitrogen. The boiler drum and the coolers at various stages for sulfur processing are also protected using low-pressure nitrogen (make sure to drain all water from them and open the drainage valves). The sulfur seals at each stage are likewise protected by low-pressure nitrogen, while the heat exchangers for quench water are protected using circulating water
