Hydrogen Bakeout Determination

[NickelMet]

Does anyone know of an existing reference that would help one determine whether or not a piping system (within a petroleum refinery) would need a hydrogen bakeout?

Lengthy references are okay, but I've been asked to develop a SHORT and SUCCINT methodology to help our planners.

Thanks!
