Reasons for the high pressure in the Klaus sulfur recovery burner
Thread Content
The pressure in our Klaus sulfur recovery burner remains quite high, at around 50 kPa, which prevents the sulfur recovery capacity from increasing; it only reaches half of the designed level. I’m not sure; with 500 m3 of low-pressure oxygen and 1500 m3 of air, the system pressure becomes quite high
The original poster, please provide more details – what is the level of acidity? Are there hydrocarbons, oil, water? Is the pressure high in the exhaust section?
Without oil or anything similar, the exhaust gas with an acidity level of 3000 has a pressure of around 20 kPa
Is the pressure high in the Klaus system? The reason has to be sought in the overall manufacturing process. Is there an exhaust treatment system? If there is, cut it out and give it a try. It is also possible to check equipment such as sulfur coolers and converters to see if there is any blockage or similar issues.
The desulfurization system that sends exhaust gas to the boiler has sulfur in the pipelines there
It seems to be a problem with the exhaust system; under normal conditions, the exhaust pressure is very low
We use the boiler’s exhaust fan to draw out the exhaust gases.
Check the pressure difference of the equipment, and observe whether there is any internal leakage in the various circulating water coolers； Checking for water presence in the acidic gas system can also lead to high pressure ； If gas is used as an auxiliary fuel, check whether there is water in the gas system
If the exhaust gas contains sulfur, does that mean the condenser and liquid sulfur catcher are not working well? Could poor insulation of the exhaust pipeline cause sulfur blockage? It also happens frequently that the catalyst collapses and blocks the condenser or something like that
There is only one reason for high burner pressure: a blockage in the downstream equipment or pipelines. Troubleshooting can be carried out using the pressure measurement points of the sulfur condenser and the sampling points on the process pipelines; it is also possible to check whether the liquid sulfur pipeline is unobstructed by using the observation ports on that pipeline. It’s easy to find the location of the blockage by conducting a check.
The high backpressure in the recovery unit is mainly due to: 1. large processing volume, 2. pipeline blockage, 3. bed blockage； Please investigate the cause carefully; this problem is not easy to resolve, and it’s possible that production will have to be halted, dear. Suggestions: 1. Conduct a thorough inspection of the insulation system of the recovery device and enhance its insulation ； 2. Check the catalyst’s activity to determine whether there is sulfur accumulation on the catalyst or similar issues; if so, carry out desulfurization procedures. As for carbon burning, our factory has not yet dared to implement it in practice. 3. Check for any blockages in the gas flow path, with a focus on key areas such as the condenser outlet and outlet pipelines, as well as the misting screens of the condenser and collector. 4. For other aspects, it is up to the personnel in your own factory who are familiar with the production processes to make judgments and decisions. If the processing capacity you mentioned cannot be increased, it is most likely due to blockages; efforts should be focused on resolving this issue! If it starts to be implemented, there are things we can discuss together
