How to deal with sulfur blockage in the pipeline that carries the Claus off-gases used for sulfur recovery to the boiler? We use the secondary Claus process. The flue gas from the incinerator contains 25.02% CO2, 2% O2, 46.07% N2, and 24.98% H2O. The pipe diameter is 350; the flow rate at the sulfur recovery outlet is 2883 NM3, at a pressure of 17 KPA and a temperature of 280°C. 1100 meters away. The pipes leading to the boiler are severely blocked, resulting in a minimum boiler temperature of 60°C. There is suspicion that the insulation in the pipeline design is inadequate. Dear sea friends, do you have any good suggestions? Escrow. Thank you!
Should insulated fabric be used? With such a long pipe, heat loss must be significant.
