ppm weight, NACE, material selection
ppm weight, NACE, material selection
(OP)
Hey,
I have been given the salt content in formation water (as NaCl). The value is 290000 ppm (weight)
I have also been given the H2S content as 7000 ppm (volume I quess).
NACE MR0175 says to divide the 7000ppm by 10000 to get the mol%. Does this work for NaCl as well?
I'm trying to select a material that would hold up in these conditions..
Thank you

RE: ppm weight, NACE, material selection
10,000 ppm is 1% by weight, so 290000 ppm weight is 29% (this is a slurry, then, or did you hit an extra 0 in your typing?), 7000 ppm is 0.7%.

So, NACE is actually saying that wt% H2S = mol% H2S ?

I'm not sure how to convert ppm NaCl to Cl- though, should have payed more attention in chemistry class I quess.
Thanks
