Stripped sour water for cutting/quench water

[natashafreta]

I would like to know if anyone is using stripped sour water for cutting/quench water.  What issues (if any) have you seen?  What concentration of NH3 and H2S is acceptable? (pH?) Is it necessary to have a closed tank or is an open tank ok?

It is common practice to use stripped sour water for coker water system make-up. Levels of H2S and NH3 in such water are typically below 10 wppm and 75 wppm respectively. Regular monitoring and controls are needed to ensure safe levels are maintained. Best regards
