Hello, I'm junior process engineer working for EPC contractor.
Recently, for cleaning purpose, our Company requested us to confirm the necessity of steam purge for acid gas flare header.
However, most relieving fluid heading to acid gas flare consists of high concentration of H2S and SO2. I'm worrying that when steam is condensed into water and contacts remaining relieving fluid compound, they seem to be converted into acidic fluid, causing corrosion issue.
I would like to know steam purge for acid gas flare header is really available and whether such cleaning method is generally used or not.
Thank you
