Chothandizira Choyeretsera Mafuta
HLN-127-4 Madzi ndi Kutupa Choletsa (Yankho Lokhala ndi Mphamvu Yochuluka Kasanu)
Zinthu Zamalonda
- Kugwira Ntchito Kwapadera Koletsa Kudzimbidwa: Kumateteza bwino ku dzimbiri ngakhale mutakhala ndi sulfide ndi chlorides wambiri. Zoletsa kulowerera zitha kukonzedwa pambuyo pochepetsa kuzizira kwa nthawi 4-5.
- Kuphatikiza Kosavuta ndi Zoletsa Kutupa: Zimagwirizana ndi ethylenediamine, monoethanolamine, ndi zina zoletsa kutupa kwa amine zachilengedwe kuti zigwiritsidwe ntchito mwachindunji.
- Chitetezo cha Zachilengedwe: Chopanda ma ayoni a Cl, P, ndi zitsulo. Zinthu zotsalira zimasungunuka m'madzi, zomwe zimapangitsa kuti pasakhale zotsatirapo zoyipa pa ntchito zokonzanso pambuyo pake.
- Kugwira Ntchito Kotsutsana ndi Kusakaniza: Kumachepetsa chizolowezi cha madzi oundana kuti asungunuke, kuonetsetsa kuti akutsatira miyezo yolamulira kuchuluka kwa ammonia nayitrogeni, COD, ndi mafuta.
- Yotsika Mtengo: Imafuna kuwonjezera ma amines achilengedwe okha, zomwe zimapangitsa kuti mtengo wonse ukhale wotsika kwambiri.
- Kugwiritsa Ntchito Kwambiri: Kwatsimikiziridwa kuti ndi kothandiza pazida zosiyanasiyana zapakhomo, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu mlengalenga ndi mu vacuum distillation mayunitsi okhala ndi mawonekedwe osiyanasiyana komanso mikhalidwe yogwirira ntchito.
Mafotokozedwe Aukadaulo
| Chizindikiro | Zizindikiro Zaukadaulo | Njira Yoyesera |
| Maonekedwe | Madzi ofiirira | Kuyang'ana Kowoneka |
| Kusungunuka | Sungunuka m'madzi ndi mowa | Kuyang'ana Kowoneka |
| pH (1% yankho lamadzi) | ≥8.0 | SH/T 0069 |
Mapulogalamu
- Ma Units Oyeretsera: Chitetezo choletsa dzimbiri pa malo ozizira omwe amatentha pang'ono mu distillation ya mlengalenga, vacuum distillation, catalytic cracking, ndi ma unit a hydrogenation.
Malangizo Ogwiritsira Ntchito
1. **Kusakaniza:** Sakanizani mankhwalawa ndi madzi nthawi 4-5 ndipo sakanizani ndi neutralizer.
2. **Kukonzekera kwa Neutralizer:** Pa zipangizo zoyeretsera mpweya komanso zotsukira mpweya, onjezani 10–20% ethylenediamine kapena 15–30% monoethanolamine pa tani imodzi ya chinthu chomalizidwa.
Kulongedza, Kusunga, ndi Chitetezo
- Zosankha Zopaka: Zimapezeka m'ma ng'oma apulasitiki a 25L, ng'oma zachitsulo kapena zapulasitiki za 200L, kapena migolo ya tani ya IBC.
- Malangizo Osungira: Sungani pamalo ozizira, ouma, komanso opumira mpweya kutentha kwa chipinda. Onetsetsani kuti chidebecho chatsekedwa. Nthawi yosungiramo zinthu ndi zaka ziwiri.
- Malangizo Oteteza: Sungani kutali ndi zinthu zomwe zimayatsa moto. Onani pepala la deta la chitetezo cha zinthu (MSDS) kuti mudziwe zambiri za chitetezo.
