Blockage in the SO2 delivery pipeline
Thread Content
The SO2 pipeline is blocked; it is suspected that elemental sulfur is the cause of this blockage. Is there any way to remove elemental sulfur?
It’s possible, but too much sulfur is required; it’s better to check for other reasons
0.3 MPa steam tracing, with enclosed discharge at the location.
I also want to ask, don’t these pipelines have associated heat tracing?
1. As the pipeline temperature rises, elemental sulfur melts; however, it is necessary to determine the fate of the molten sulfur after it melts； 2. Cleaning of pipelines using high-pressure water guns (this method is generally quite thorough, but the pipelines need to be shut down first). 3. Using steam at 1.0 Mpa to purge the pipelines toward subsequent equipment, with enhanced drainage from those subsequent devices ；
