Problem of blocked exhaust seal vent pipe in catalytic unit
Thread Content
The problem of clogged exhaust seals in catalytic units – have you encountered this issue? How can it be resolved? Using air for backflow cleaning doesn’t give very good results
It is recommended to use copper tubes for heat tracing to prevent corrosion products caused by low temperatures from blocking the tubes
A vacuum pump can be added, and it’s important to ensure that the steam used for sealing is saturated and free of water. We once considered using main air or pressurized air as the sealing gas
It has never been blocked; our steam vent is kept open at all times, and it is required that the operator check it during each inspection
Optimize the piping by minimizing bends as much as possible, ensure there is a slope, insulate the vent pipes to reduce condensation
