Real Specifications
| Named target odor compounds (Perry brochure) | H2S, Aldehydes, NH3, Amines, Acetic Acids, Ketones | perry-fiberglass.md |
| Reference NH3 install | "NH3 (Ammonia) chemical scrubber for an industrial plant" — three vessels shown loaded for delivery | perry-fiberglass.md |
| Cyanide destruction two-step gas hazard | Stage 1 pH must be adjusted rapidly to convert cyanide to cyanate — done too slowly, it risks releasing extremely toxic cyanogen chloride gas | gf-signet-application-solutions.md |
| Cyanide destruction batch-process setpoints | pH raised to 11.5 with sodium hydroxide, chlorine added until ORP reaches +450mV; acid injection must be manually locked out below pH 11 | gf-signet-application-solutions.md |
GF Signet's own batch cyanide-destruction warning is explicit: acid injection must be manually locked out to prevent pH dropping below 11, because below that point the process both fails to fully oxidize cyanide to cyanate and risks releasing toxic cyanogen chloride gas.
Cyanide destruction generates its own gas hazard mid-process — GF Signet's own documentation requires pH to be adjusted rapidly in Stage 1, or locked out below pH 11 in the batch process, specifically to avoid releasing cyanogen chloride gas. A scrubber sized only for the ammonia and standard odor compounds Perry's APOLLO/OMEGA/ODYSSEY line targets is the wrong spec if the upstream cyanide-destruction pH control isn't accounted for in the same system design.
