I did a blow down at Santa Rosa station in Peru in 2006, did you ever do that on start up?
Did they ground anything in the US if you did it?
We grounded NOTHING when we did, all that gas going out the pipe at high velocity...man, I definitely did NOT want to stand near that thing!
If you want an outline construction/start up procedure, I will give you one that I stole, you supply the ANSI/ASME references, from 1984 worked in the middle of Boston during a gas conversion of two 380 MW units.
