Choletsa Kutupa kwa Hydrogenation cha HLN-124
Zinthu Zamalonda
- Kuletsa Kuchuluka kwa Madzi: Kumapanga mankhwala osungunuka m'madzi ndi mchere wa ammonium, kuteteza mvula yochepa kutentha komanso dzimbiri losakwanira lomwe limayambitsidwa ndi NH4HS deposits.
- Kuletsa Kudzimbiritsa: Kumapanga filimu yoteteza yolimba komanso yokhazikika pamwamba pa zitsulo, kuchepetsa NH4HS ndi dzimbiri la H2S lonyowa.
- Kuletsa: Kuletsa HCl ndi H2S zofupikitsidwa, kuteteza dzimbiri la asidi mu zipangizo.
- Chitetezo cha Zachilengedwe: Chopanda zitsulo ndi zinthu zovulaza, sichichita ndi zimbudzi zokhala ndi sulfure, ndipo sichimakhudza machitidwe amafuta kapena zinthu zina.

Mapulogalamu
- Kuletsa Kutupa kwa Ammonium Bisulfide: Kumachepetsa kukokoloka ndi kuipitsidwa kwa NH4HS mu ma hydrogenation reactors ndi zida zina zogwirizana nazo.
- Kupewa Kudzimbidwa ndi Hydrogen Sulfide Yonyowa: Kumateteza makina ozizira pamwamba pa makina oyeretsera ku dzimbiri la H2S lonyowa.
Malangizo Ogwiritsira Ntchito
1. **Kukonzekera:** Pompani mankhwalawa mu thanki yosungiramo zinthu zoletsa dzimbiri ndipo sakanizani ndi madzi opanda mchere kapena ofewa mpaka kuchuluka komwe mukufuna.
2. **Malo Olowetsa:** Akulimbikitsidwa kugwiritsa ntchito malo olowera mpweya a condenser pamwamba pa nsanja. Gwiritsani ntchito mapaipi achitsulo chosapanga dzimbiri a DN15, kuonetsetsa kuti doko lolowetsa mpweya likufika pakati pa mapaipi.
3. **Mlingo:** Mlingo wamba umayambira pa 10μg/g mpaka 30μg/g kutengera kuchuluka kwa mafuta okonzedwa. Sinthani malinga ndi kuchuluka kwa mafuta osakonzedwa a S, N, ndi Cl.
4. **Asanachite Passivation:** Pa masiku 5 oyambirira, onjezerani mlingo kufika pa 30-50ppm kuti mupange filimu yoteteza yolimba.
5. **Kukonza Mapaipi:** Musanasinthe mitundu ya zoletsa dzimbiri, tsukani ndi kutsuka mapaipi obayira jakisoni bwino kuti mupewe kutsekeka.
Chitsimikizo cha Magwiridwe Antchito
- Imasunga kuchuluka kwa ayoni achitsulo m'madzi otayira okhala ndi sulfure pa ≤3mg/L.
- Sizimayambitsa emulsification kapena kusokoneza kulekanitsidwa kwa mafuta ndi madzi.
- Sizimakhudza kukhazikika kwa chipangizo kapena khalidwe la chinthu.
- Zotetezeka pa njira zotsukira zinyalala zomwe zili pansi pa madzi komanso njira zotsatirira.
Kulongedza, Kusunga, ndi Chitetezo
- Ma CD: Amapezeka m'ma ng'oma apulasitiki a 25L, ng'oma zachitsulo kapena zapulasitiki za 200L, kapena m'mabotolo a tani a IBC.
- Kusungira: Sungani pamalo ozizira, ouma, komanso opumira mpweya. Nthawi yosungira: zaka ziwiri.
- Chitetezo: Sungani kutali ndi magwero a moto. Onani pepala la deta la chitetezo cha zinthu (MSDS) kuti mudziwe zambiri zokhudza chitetezo.
