Propylene R1270
Propylene yog ib qho tseem ceeb tshaj plaws raw cov ntaub ntawv nyob rau hauv lub petrochemical kev lag luam thiab yog ubiquitous nyob rau hauv peb lub neej txhua hnub - los ntawm cov khoom yas thiab ntim cov ntaub ntawv mus rau lub tsheb bumpers, khoom kho mob, khaub ncaws, thiab coatings. Nws kuj yog qhov thib ob tshaj plaws ua olefin tom qab ethylene.
Nov yog cov lus qhia ceev ceev ntawm nws cov yam ntxwv tseem ceeb hauv cov lus hauv qab no:
| Yam khoom | Paub meej |
|---|---|
| Cov ntaub ntawv yooj yim | Tshuaj formula: C₃H₆; Lub npe Askiv: Propylene / Propene; Cov pa roj tsis muaj xim nyob rau hauv chav tsev kub nrog cov pa hydrocarbon me me - zoo li tsw. |
| Qhov tseem ceeb Physicochemical Parameters | Boiling point: approx . -47.6℃; Melting point: approx . -185℃; Kev txwv tawg hauv huab cua: 2% -11% (los ntawm ntim); Flammable gas. |
| Tej Yam Tseem Ceeb | Cov nplaim taws heev; cov pa roj yog hnyav dua li huab cua, yuav kis mus rau hauv av thaum xau, thiab ua rau muaj kev pheej hmoo flashback nyob ze qhov chaw taws teeb. Cov kua propylene tuaj yeem ua raufrostbitenyob rau ntawm daim tawv nqaij thiab muaj cov tshuaj narcotic me ntsis. |
💎 Daim ntawv thov tseem ceeb: Los ntawm cov khoom siv raw mus rau cov khoom kawg
Propylene yog ib qho yooj yim lub tsev thaiv rau peb cov khoom siv hluavtaws loj (yas, hluavtaws roj hmab, thiab hluavtaws fibers), nrog rau ntau yam khoom siv hauv qab.
Polypropylene (kwv yees . 70%): Qhov no yogloj tshaj plaws downstream khoomntawm propylene. Polypropylene yog ib qho dav dav - lub hom phiaj yas siv dav hauv cov hnab ntim khoom, cov khoom siv hauv tsev, tsheb bumpers, khoom siv kho mob, thiab lwm yam.
Propylene Oxide (PO): Feem ntau yog siv los tsim polyurethane foams, uas yog ib qho tseem ceeb rau cov mos foams nyob rau hauv sofas, txaj, lub rooj zaum tsheb, thiab lwm yam.
Acrylonitrile: Cov khoom siv tseem ceeb rau ABS engineering yas, acrylic fibers (synthetic wool), thiab nitrile roj hmab.
Lwm yam tshuaj: Propylene kuj tseem siv los tsim cov isopropanol (cov kuab tshuaj), acetone, acrylic acid (coatings, adhesives), thiab butanol / octanol (plasticizers), thiab lwm yam.
⚙️ Cov Txheej Txheem Ntau Lawm: Yuav Ua Li Cas Propylene tau txais
Tam sim no, muaj plaub txoj kev tsim khoom loj rau propylene thoob ntiaj teb:
Chav Cracking: Ib txoj kev siv naphtha thiab lwm yam khoom noj, feem ntau tsom rau kev tsim cov ethylene; propylene yog cov khoom lag luam tseem ceeb nrog cov txiaj ntsig ntawm kwv yees li . 14% -18%.
Cov kua dej Catalytic Cracking (FCC): Nyob rau hauv cov roj refineries, propylene yog tsim raws li ib tug byproduct thaum hnyav roj hloov mus rau hauv roj av thiab diesel, nrog ib tug yield ntawm approx . 3% -8%.
Propane Dehydrogenation (PDH): A kev loj hlob sai ntawm cov txheej txheem tseem ceeb, tshwj xeeb tsim los tsim propylene los ntawm propane. Nws cov txiaj ntsig suav nrog cov khoom lag luam siab purity thiab cov txiaj ntsig txog li 85% -90%.
Coal/Methanol-rau-Olefins (CTO/MTO): Haum rau cov teb chaws nplua nuj nyob hauv cov thee tab sis tsis muaj roj thiab roj. Propylene yog tsim los ntawm thee - muab tau los ntawm methanol.
🚢 Cia, Thauj & Kev Nyab Xeeb: Kev nruj tshwj xeeb
Vim nws cov nplaim hluav taws kub thiab kub kub tsis tshua muaj siab (-47.6 degree), propylene yuav tsum tau tuav tshwj xeeb rau kev khaws cia thiab kev thauj mus los.
Txoj kev khaws cia: Nws yuav tsum khaws cia hauv qabsiab siabkhaws cia rau hauv lub xeev liquefied, los yogcryogenically(feem ntau qis dua -47 degree) rau cov tub yees liquefied cia, siv tshwj xeeb kheej kheej siab tso tsheb hlau luam lossis cylindrical cryogenic tso tsheb hlau luam.
Kev thauj mus los: Ntev- kev thauj mus los yog siv rau siabsiab tankers(land) thiabsiab / tub yees nkoj(dej).
Kev Tswj Xyuas Kev Nyab Xeeb: propylene yog cais raws li aChav Kawm 2.1 muaj tshuaj lom neeg, thiab tag nrho cov kev khiav hauj lwm thiab cov lus teb thaum muaj xwm ceev yuav tsum ua raws li cov cai nruj.
