HLN-127 Neutralizing Corrosion Inhibitor yeAtmospheric uye Vacuum Distillation Units
Zvimiro zveChigadzirwa
- Kudzora pH: Inochengetedza pH yemvura yakagayiwa mukati me5.5 kusvika 6.0, ichienzanisa ngura yeasidhi uye ngura isiri muchiyero inokonzerwa neNH4Cl neFeS.
- Kushanda Nesimba: Kunoderedza kushandiswa kwezvinhu zvinokuvadza neanopfuura 20% zvichienzaniswa nezvigadzirwa zvakafanana, zvichiita kuti ngura isanyanya kukuvadza ne ≥90%.
- Kurwisa Kusanganiswa Kwemafuta: Kunoderedza katsika kemvura yakagayiwa kugadzira ma emulsion, kuderedza huwandu hwemafuta uye COD mumvura.
- Kuchengetedzwa Kwezvakatipoteredza: Hapana simbi nezvinhu zvinokuvadza, zvichiita kuti pasave nemigumisiro yakaipa pamagetsi ekugadzirisa kana masisitimu ekuchenesa mvura yakasviba.

Mashandisirwo
- Kudzora Kuora: Kunodzivirira kubva pakuora kweHCl-H2S-H2O muzvinhu zvinotonhodza zvinotonhorera pamusoro pemayuniti emhepo neanopisa.
- Kuderedza Kukura KwemaScale: Kunodzivirira kukwira kweammonium chloride (NH4Cl) uye iron sulfide (FeS), kudzivirira ngura yechipiri uye kuona kuti michina inogara kwenguva refu.
Mirayiridzo Yekushandisa
1. **Kugadzirira:** Pomba chigadzirwa mutangi rekuchengetera zvinhu zvinodzivisa ngura wobva wasanganisa nemvura isina mineral kana kuti isina oxygen kusvika pakuwanda kwainodiwa.
2. **Nzvimbo dzeKubaya:** Shandisa pombi yekuyera kubaya mushonga usati waisa mvura pamutsetse wemvura uri pamusoro pekoramu yekudiridza, zviri nani kuti uve pedyo nenzvimbo ine dova.
3. **Chipimo:** Chinja mwero wejekiseni kuti pH yemvura irambe iri pakati pe5.5 ne8.0. Chipimo chakajairika: 10-40ppm (zvichienderana nemafuta asina kucheneswa). Madhigiri ekutanga anogona kuwedzerwa kuti pave nekuenzana kwemvura.
4. **Kugadziriswa Kwakajairwa:** Chinja mwero wejekiseni zvichibva pahunhu hwemafuta asina kucheneswa (organic chlorine nesarufa), huwandu hweion ye chloride inonyungudika, uye data rekutarisa ngura.
Vimbiso Yekushanda
- Inochengetedza huwandu hweiron ion mumvura yakavharirwa panzvimbo dzakaoma (semuenzaniso, primary distillation tower, atmospheric tower, uye vacuum tower tower) iri ≤3mg/L.
- Hazvikonzere kusanganiswa kwemafuta nemvura kana kukanganisa kupatsanurwa kwemafuta nemvura, kugadzikana kwemudziyo, kana mhando yechigadzirwa.
- Hapana migumisiro yakaipa pamagetsi ekugadzirisa mvura kana masisitimu ekuchenesa mvura yakasviba.
- Chipimo Chinokurudzirwa: Zvichibva pahunhu hwemafuta asina kucheneswa, tafura inotevera inopa gwara rehuwandu hwemajekiseni e neutralizer.
Tafura yeChipimo Chinokurudzirwa

Kurongedza, Kuchengeta, uye Kuchengetedzeka
- Kurongedza: Inowanikwa mumadhiramu epurasitiki e25L, madhiramu esimbi e200L kana epurasitiki, kana madhiramu eIBC ton.
- Kuchengetera: Chengeta munzvimbo inotonhorera, yakaoma, uye ine mhepo inofefetera patembiricha yemumba. Nguva yesherufu: makore maviri.
- Kuchengetedzeka: Chengeta kure nezvinobvira moto. Tarisa kuMaterial Safety Data Sheet (MSDS) kuti uwane rumwe ruzivo rwekuchengetedza.
