HLN-127 Neutralizing Corrosion Inhibitor no nā ʻĀpana Distillation Atmospheric a me Vacuum
Nā Hiʻohiʻona Huahana
- Ka Mana pH: Mālama i ka pH o ka wai i hoʻopaʻa ʻia i loko o 5.5 a 6.0, e kaulike ana i ka pala ʻakika a me ka pala haʻahaʻa i hoʻokumu ʻia e NH4Cl a me FeS.
- Hana Kūpono: Hoʻemi i ka hoʻohana ʻana o nā mea hana ma mua o 20% i hoʻohālikelike ʻia me nā huahana like, e hoʻokō ana i ka helu kāohi ʻana o ka palaho o ≥90%.
- Anti-Emulsification: Hoʻēmi i ke ʻano o ka wai i hoʻopaʻa ʻia e hana i nā emulsions, e hoʻohaʻahaʻa ana i ka nui o ka aila a me COD i loko o ka pae wai.
- Palekana no ke Kaiapuni: ʻAʻohe metala a me nā mea ʻino, e hōʻoiaʻiʻo ana ʻaʻohe hopena maikaʻi ʻole i nā ʻāpana hana ma lalo a i ʻole nā ʻōnaehana mālama wai ʻino.

- Ka Mana ʻAna i ka ʻAi ʻOle: Mālama i ka ʻai ʻole ʻana o HCl-H2S-H2O i nā ʻōnaehana hoʻoluʻu condensing ma luna o nā ʻāpana distillation lewa a me ka vacuum.
- Hoʻēmi i ka Unahi: Kāohi i ka ʻānai ammonium chloride (NH4Cl) a me ka iron sulfide (FeS) scaling, e pale ana i ka pala lua a me ka hōʻoia ʻana i ke ola lōʻihi o nā lako.
Nā Kuhikuhi Hoʻohana
1. **Hoʻomākaukau:** E hoʻokomo i ka huahana i loko o kahi pahu mālama mea pale i ka palaho a hoʻokahe me ka wai demineralized a i ʻole deoxygenated i ka nui e pono ai.
2. **Nā Kiko Hoʻokomo:** E hoʻohana i ka pamu ana e hoʻokomo i ka mea pale ma mua o ke kiko hoʻokomo wai ma ka laina hoʻomāhu ma ka piko o ke kolamu distillation, kokoke i ke kiko hau.
3. **Ka nui o ka lāʻau:** E hoʻoponopono i nā helu inikini e mālama i ka pH o ka condensate ma waena o 5.5 a me 8.0. Ka nui maʻamau: 10-40ppm (e pili ana i ka ʻaila maka). Hiki ke hoʻonui ʻia nā nui mua e hoʻokumu i ke kaulike adsorption.
4. **Hoʻoponopono Kūikawā:** Hoʻololi i nā helu inikini e pili ana i nā waiwai ʻaila maka (ka nui o ka chlorine organik a me ka sulfur), nā pae ion condensate chloride, a me ka ʻikepili nānā ʻana i ka palaho.
Palapala Hoʻokō Hana
- Mālama i ka nui o ka ion hao i loko o ka wai i hoʻopaʻa ʻia ma nā wahi koʻikoʻi (e like me ka hale kiaʻi distillation mua, ka hale kiaʻi lewa, a me nā piko o ka hale kiaʻi vacuum) he ≤3mg/L.
- ʻAʻole ia e hoʻoulu i ka emulsification a i ʻole e hoʻopilikia i ka hoʻokaʻawale ʻaila-wai, ke kūpaʻa o ka hāmeʻa, a i ʻole ka maikaʻi o ka huahana.
- ʻAʻohe hopena maikaʻi ʻole ma nā ʻāpana hana ma hope a i ʻole nā ʻōnaehana mālama wai ʻino.
- Ka nui i ʻōlelo ʻia: Ma muli o nā ʻano aila maka, hāʻawi ka papa ma lalo nei i ke alakaʻi no nā helu inikini neutralizer.
