Do members have any experience or recommendations for clean up BF3 piping/equipment for hot work maintenance?
Operations identified a "black residue" that remains in 316 stainless steel piping when they open up the system to do hot work maintenance. We're still waiting for analysis results of the sample of the black residue we sent to a lab, but it's likely residual boron trifluoride compounds/degraded BF3 compounds.
We're considering soda ash wash similar to clean up procedures to neutralize sulfur based compounds, but I'm not sure if that's the appropriate chemical to use here or if that'd create other unwanted compounds in the system.
Thanks for your help
