Thank both of you for the help. We do not have a deaerator, so your numbers may be different. We are supposed to maintain about 5-20 ppb residual, but I don't see the need if our oxygen level is within specification. Our only choices for sampling points are condensate, feed (after chemical...
The sample point we have is downstream of our chemical addition, so if we are dosing hydrazine, we get erroneously high results. It sounds like that is still the best sample point, but we need to get operators to pay attention to chemical adds. Does that sound like a fair assessment?
Can anyone tell me where the best sample point for hydrazine would be on a HRSG. We had been sampling on the condensate, but I thought it would be better to sample on a drum. Any other ideas.
cub3bead,
Thanks for the reply. Your questions answering questions is what I was looking for. I was trying to voice my concerns over this move to our management but was shut out. Your questions are similar to the ones I had, particularly what is the overall impact. From what I've heard...
Just wondering if there are any other power plant folks out there who are ZLD. We are going through a lot of growing pains at my plant. Nalco has us switching from ferric sulfate as our primary coagulant in our clarifiers to a polymer coagulant that they sell. Has anyone else seen a similar...
