Acrylonitrile yog tsim los ntawm kev siv propylene thiab ammonia li cov ntaub ntawv raw, los ntawm oxidation cov tshuaj tiv thaiv thiab kho cov txheej txheem. Nws yog cov organic compound nrog cov kua mis cov tshuaj c3h3n, cov pa tsw ntxhiab tsw muaj pa, thiab nws yooj yim rau cov nplaim taws thiab cua sov, thiab emits kom sov roj , thiab reacts ua txhaum nrog oxidizers, muaj zog acids, hauv paus muaj zog, amines thiab bromine.

Nws yog tsuas yog siv los ua cov khoom siv raw rau acrylic thiab tus ABS / San Resin, thiab tseem muaj siv roj ntau lawm, muab cov roj hmab, cov roj hmab hluavtaws, latab, thiab lwm yam.

Acrylonitrile kev siv tes ua lag luam

Acrylonitrile yog cov khoom siv hluav taws xob tseem ceeb rau peb cov roj hmab loj (acrylic thiab acrylamide, uas muaj nyiaj ntau dua 80% ntawm kev noj ntau dua Acrylonitrile. Nyob rau hauv xyoo tas los, Tuam Tshoj tau dhau los ua ib lub tebchaws nrawm tshaj plaws hauv lub ntiaj teb Acrylonitrile Markiance thiab kev lag luam tsheb. Cov khoom siv hauv qab daus yog siv dav hauv ntau daim teb ntawm kev lag luam hauv tebchaws, xws li cov khoom siv hauv tsev, xws li cov khoom siv hauv tsev, hnav ris tsho, thiab khoom siv.

Acrylonitrile yog tsim los ntawm propylene thiab ammonia los ntawm oxidation kev tsim khoom, thiab siv tau dav hauv cov chaw tsim khoom, thiab cov pa roj carbon monoxide yog daim ntawv thov maj mam xav tau yav tom ntej.

Cov pa roj carbon fiber, raws li ib qho tseem ceeb siv downtrile ntawm acrylonitrile, yog cov khoom tshiab tam sim no tau tsom rau kev tshawb fawb thiab ntau lawm hauv Suav teb. Carbon fiber tau dhau los ua cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv me me, thiab maj mam coj cov ntaub ntawv cov khoom siv qub, thiab tau dhau los ua cov ntawv thov tseem ceeb hauv zej zog.

Raws li Tuam Tshoj txoj kev lag luam txuas ntxiv txhim kho ntawm kev nrawm nrawm, qhov kev thov rau cov khoom siv roj carbon thiab nws cov ntaub ntawv sib xyaw ua ke txuas ntxiv mus. Raws li kev txheeb cais, qhov kev thov rau carbon fiber ntau hauv Suav mus txog 48,800 tons hauv 2020, nce ntxiv ntawm 29% dhau 2019.

Nrog kev txhim kho kev kawm txuas ntxiv ntawm science thiab thev naus laus zis, tshuaj acrylonitrile ua si pom cov qauv loj heev.
Ua ntej tshaj plaws, txoj kev ntawm acrylonitrile ntau lawm siv Profrane raws li pub mis yog maj tau nce.
Thib ob, cov kev tshawb fawb ntawm cov catalysts tshiab txuas ntxiv mus ua cov ncauj lus tshawb fawb rau cov kws tshawb fawb hauv tsev thiab txawv teb chaws.
Thib peb, qhov loj ntawm cov nroj tsuag.
Thib plaub, lub zog txuag thiab emission txo, cov txheej txheem optimization yog qhov tseem ceeb ntxiv.
Qhov thib tsib, kev kho dej khib nyiab tau dhau los ua cov ntsiab lus tshawb fawb tseem ceeb.

Acrylonitrile Loj Loj Ntau Lawm

Suav teb cov actrylonitrile ntau lawm cov tsev yog feem ntau muaj nyob rau hauv kev lag luam uas muaj los ntawm Tuam Tshoj Petrorisum & ChineseCec) thiab Tuam Tshoj National Petroration (CMPC). Ntawm lawv, tag nrho cov peev txheej ntawm sinopec (suav nrog kev sib koom ua ke) yog 860,000 tons, suav rau tag nrho cov peev xwm; Cov peev txheej ntau lawm ntawm Petrochina yog 700,000 tons, nyiaj txiag rau 28.3% ntawm lub peev xwm ntau lawm; Muaj peev xwm ntau lawm ntawm cov lag luam ntiag tug Jiangsu Searborn petrochemical, fitd. tons, tus kheej rau kev sib xyaw ua ke muaj peev xwm ntawm kev sib xyaw ntawm 36.8%.

Txij li thaum ib nrab ntawm 2021, theem ob ntawm ZPMC nrog 260,000 tons / xyoo, theem ob, theem thib ob ntawm Srbang nrog 260,000 tons / Xyoo ntawm Acrylonitrile tau muab tso rau hauv kev ua haujlwm ib zaug tom qab lwm tus, thiab lub peev txheej tshiab tau mus txog 910, thiab tag nrho cov acrylonitrile muaj peev xwm tau mus txog 3.419 lab tons / xyoo.

Qhov kev nthuav dav ntawm acrylonitrile muaj peev xwm tsis nres ntawm no. Nws tau nkag siab txog qhov ntawd nyob rau hauv 2022, tshiab 260,000 tons / xyoo acrylonitrile nroj tsuag yuav muab tso rau hauv Guangdong thiab 200,000 tons / Xyoo Cog hauv Hainan. Lub peev xwm tshiab ua haujlwm ntau lawm tsis txwv rau Suav teb, tab sis yuav muab faib rau hauv Hainan tshiab yuav muab faib rau hauv cov haujlwm tshiab hauv Suav teb thiab cov chaw ua lag luam sab qab teb thiab nws Kuj yog yooj yim heev rau kev xa tawm los ntawm hiav txwv.

Qhov muaj peev xwm nce ntau heev coj tau nce toj hauv kev tsim khoom. Jinlian cov ntaub ntawv qhia tau tias Suav cov acrylonitrile ntau lawm txuas ntxiv rau 2.317 xyoo , nrog thawj cov cim ntawm overcapacity hauv kev lag luam.

Kev cob qhia yav tom ntej ntawm Acrylonitrile

Nyob rau hauv lub xyoo 2021 nyuam qhuav dhau los, acrylolonitrile export ntau tshaj li cov neeg tuaj txawv teb chaws rau thawj zaug. Tag nrho cov khoom lag luam ntawm Acrylonittrile cov khoom xyoo tas los yog 203,800 tons, qis dua 33.55 tons, nce ntxiv ntawm 188.69% los ntawm xyoo dhau los.

Qhov no yog unseparable los ntawm kev tso tawm ntawm cov tshiab ntau lawm hauv Suav teb thiab kev lag luam yog nyob rau hauv lub xeev ntawm kev hloov pauv kom muaj kev sib npaug nruj. Tsis tas li ntawd, ib qho ntawm cov neeg European thiab cov neeg Asmeskas tau nres, thaum cov nqi neeg Esxias tau qis dua li Neeg Esxias, tus nqi European thiab Asmeskas thiab Asmeskas tus nqi, uas Pab Tuam Tshoj Acrylonitrile Expards nthuav tawm kom nthuav, suav nrog Taiwan xeev ntawm Tuam Tshoj, ze rau Yelesa, Is Nrias teb thiab qaib cov txwv.

Qhov nce nyob rau hauv export ntim ntim tau nrog ib txoj kev nce qib siab rau hauv tus naj npawb ntawm lub teb chaws uas xa tawm. Sij hawm dhau los, Suav teb cov acrylonitrile export cov khoom lag luam tau raug xa mus rau South Kauslim thiab Is Nrias teb. 2021, nrog rau lub ntsws ua haujlwm txawv teb chaws, acrylonitrile export ntim ntau dua thiab sporadically xa mus rau European lag luam, koom nrog xya lub tebchaws thiab cov kab ke.

Nws tau kwv yees tias kev loj hlob ntawm acrylonitrile ntau lawm hauv Suav teb tau nce ntxiv, thiab yav tom ntej kev xa tawm ntawm Acrylonitrile nyob hauv Suav teb yuav tsum tau Txhawm rau kov ib qho siab ntawm 300,000 tons hauv 2022, yog li txo lub siab ntawm kev ua lag luam Suav.
