At a power plant we use sodium bisulfide to scavenge oxygen from boiler feedwater.  Some of this bisulfide will wind up in the steam going to the turbine.  The turbine manufacturers have a sodium in steam limit of 3 to 5 ppb. 

 

1) Is this limit established to prevent chlorides from attacking the turbine components?

2) What is reason for sodium limit?  

 

3) Is sodium bisulfide is a concern for turbine protection.

4) If a sodium analyzer is used for measuring sodium concentration in steam, will it measure sodium from both Sodium chloride, Sodium bisulfite and sodium hydroxide etc ? (Like combined sodium concentration or just individual sodium type compound concentration)
