Sulfidation Question
Sulfidation Question
(OP)
Hey, guys.
Just have a quick question about which of the following sulfidizing conditions is more severe:
Ar-5% H2-5% CO-1% CO2-0.15% H2S-0.1% H20 @ 1400° F
or
90% na2so4 + 10% kci @ 1600° F
Any clarification will be greatly appreciated.

RE: Sulfidation Question
Meanwhile, Na2SO4 can sulfidize the heck out most Cr/Ni/Fe/Mo alloys; look for information on "hot corrosion".
RE: Sulfidation Question
Alloys, 218, 686 and L605. If subjected to both conditions for the same duration, would all alloys find a same condition more intolerable than the other?
RE: Sulfidation Question
So altogether, they're alloys 218, 686, MP159, HR-160 and L605.
Also, I should mention that the 1400 F condition also includes an equilibrium sulfur partial pressure of 10 -6 (negative six exponent).
