Nthawi ya 11:10 pa Novembara 8, chopangidwa ndi polyester ethylene glycol cha Yulin Chemical Co., Ltd. cha Shaanxi Coal Group chinakhazikitsidwa mwalamulo!Aka ndi koyamba kuti zinthu za polyester grade ethylene glycol zopangidwa ndi Yulin Chemical Co., Ltd., zomwe zimakwaniritsa zofunikira za GB/T4649-2018, zimatumizidwa ku Zhejiang Hengyi Group Co., Ltd., fakitale yodziwika bwino ya polyester. ku China.
Mtengo utapitilira kutsika ndikutsika kwatsopano mchaka, tsogolo la ethylene glycol lidalowa pagawo lophatikizana.M'masiku aposachedwa, poyerekeza ndi PTA ndi ulusi wapakatikati pamakampani omwewo, mtengo wa ethylene glycol udakweranso kwambiri, pomwe udatsogolera gawo lonse la polyester."Icho" chofooka kwambiri mu gawo la polyester chinayamba mwadzidzidzi.Kodi ndi “nsomba zamchere”?
Posachedwapa, mtengo waethylene glycolkuwonjezerekanso pamlingo wochepa, kuchititsa kukwera kwa mankhwala ambiri.Pankhani imeneyi, Shi Jiaping, katswiri wamkulu wa Huarui Information, anafotokoza kuti, kumbali imodzi, kutuluka kwa mbali ya ethylene glycol yoperekera kunali koonekeratu.Mu November, zoweta ethylene glycol poyambira katundu anali atatsika kwa 55% - 56%, pamene kupanga mpweya kuti ethylene glycol kuyambira katundu anali watsika pafupifupi 30% - 33%, makamaka mbiri otsika.Kumbali ina, mtengo wa ethylene glycol wagwera pamlingo wochepa, womwe wapatuka kwambiri pakuwerengera.Pakalipano, malingaliro a msika atenthedwa, ndipo zogulitsa zomwe zimakhala ndi phindu lochulukirapo kumayambiriro koyambirira ziyenera kukonzedwa.
Posachedwapa, tsogolo la ethylene glycol linasintha ndikudzuka, lomwe linali "losiyana" mu gawo la polyester.M'malo mwake, inali mtundu wokonzanso mtengo pambuyo poti mabetcha onse oyipa adagulitsidwa.M'kupita kwa nthawi, pali zida zambiri zomwe zikuyembekezeka kupangidwa m'tsogolomu.Komabe, pansi pamalingaliro opanda chiyembekezo chotere, kuphatikiza kuchotsedwa kwazinthu zing'onozing'ono padoko komanso kulimbikitsidwa kwa nthawi yayitali kuchokera ku mfundo zazikuluzikulu, zidzapereka chiwongolero chokwera cha ethylene glycol yocheperako.Zotsatira zake, kukwera kwaposachedwa kwa ethylene glycol kuli bwino kuposa zinthu zina za polyester.
1. Mphamvu zopangira zimapitilizidwa bwino, ndipo kuthekera kwa malasha ku ethylene glycol ndikwabwino.
Malinga ndi Kuzama Kwambiri kwa China Ethylene Glycol Industry Development and Future Investment Research Report (2022-2029) yotulutsidwa ndi Guanyan Report Network, m'zaka zaposachedwa, msika wapadziko lonse wa ethylene glycol wakula kwambiri, ndipo mphamvu yopanga ethylene glycol ikuwonjezeka chaka. ndi chaka.Mu 2021, mphamvu yapadziko lonse lapansi yopanga ethylene glycol idzawonjezeka ndi 19.4% chaka chilichonse, ndipo zotulukapo zidzakwera ndi 7.5% chaka chilichonse.Pansi pa izi, mphamvu zopangira ndi kutulutsa kwamakampani aku China ethylene glycol zikuchulukiranso chaka ndi chaka.
Pankhani ya kuchuluka kwa kupanga, pomwe dziko limayang'anira kwambiri makampani a ethylene glycol, malangizo oyenera ndi mfundo zothandizira monga Fomula Yolimbikitsa Kukweza ndi Kugwiritsa Ntchito Ukadaulo ndi Zogulitsa mu Petrochemical ndi Chemical Viwanda mu 2021, Malingaliro Otsogolera pa Kupititsa patsogolo. Chitukuko Chapamwamba cha Makampani a Petrochemical ndi Chemical mu "Mapulani a Zaka khumi ndi zinayi" ndi Malingaliro Otsogolera pa Kupititsa patsogolo Kwapamwamba kwa Makampani a Chemical Fiber mu 2022 akupitiriza kuperekedwa, ndipo malo oyendetsera mafakitale akupitiriza kukhala abwino, ethylene glycol ya ku China. mphamvu yopanga ikuwonjezeka chaka ndi chaka.Malinga ndi deta, mphamvu ya kupanga ethylene glycol ku China idzawonjezeka kuchokera ku matani 8.32 miliyoni kufika matani 21.45 miliyoni kuchokera ku 2017 mpaka 2021, ndi kukula kwapakati pachaka pafupifupi 31%.
Pankhani ya kuchuluka kwa kugwiritsa ntchito mphamvu, kuchuluka kwa kugwiritsidwa ntchito kwa mphamvu ya ethylene glycol ku China ndikotsika pakali pano, komwe kunali pafupifupi 68.63% mu 2017;Idzakwera kufika pa 73.42% pofika 2019. Komabe, kuyambira 2020 mpaka 2021, chifukwa cha vuto la kudzipatula kwa mliri kunyumba, kukonza kachipangizo ka ethylene glycol, kuwerengera mphamvu ndi kukwera mtengo kwa malasha, zoweta za ethylene glycol zoyambira ndizochepa, ndipo zonse. mafakitale ayamba kuchepa kwambiri, zomwe zimapangitsa kuti ethylene glycol magwiritsidwe ntchito ku China atsike mpaka 60.06% ndi 55.01% motsatana m'zaka ziwiri zapitazi.
Pankhani ya zotulutsa, ndikukula kwa msika wa ethylene glycol komanso kuchuluka kwazomwe zimafunikira kutsika, zomwe zikuwonetsa zikuwonetsanso kukula kwapachaka.Kuchokera ku 2017 mpaka 2021, kutulutsa kwa ethylene glycol ku China kudakwera kuchokera ku matani 5.71 miliyoni kufika matani 11.8 miliyoni, ndipo kukula kwake kwawonetsanso kukwera m'zaka ziwiri zapitazi, motsogozedwa ndi kukula kwakukulu kwa mphamvu yake yopanga.Mu 2021, kuchuluka kwa ethylene glycol ku China kunali pafupifupi 21.65% pachaka, 2.63 peresenti yoposa ija mu 2020.
Kuchokera pakusintha kwa mphamvu yaku China ethylene glycol, zitha kuwoneka kuti mphamvu yaku China ya ethylene glycol yapitilizidwanso bwino m'zaka zisanu zapitazi, ndipo makampaniwa ali pagawo lakukula ndi chitukuko.
Pankhani yamakampani, pali njira zitatu zopangira ethylene glycol ku China: kuphatikiza (naphtha/ethylene process), MTO (methanol to olefin) ndi malasha ku ethylene glycol.Pakalipano, chifukwa cha luso lamakono la petroleum kupita ku ethylene glycol ku China, yomwe ndi njira yodziwika bwino, mphamvu yopangira mafuta ku ethylene glycol imakhala yochuluka kwambiri.Mu 2021, mphamvu yopanga mafuta a petroleum ku ethylene glycol ku China idzawerengera zoposa 60%, ndipo zotsatira zake zidzaposa matani 7 miliyoni;Chachiwiri ndi malasha kuti luso ethylene glycol (njira malasha ndi ntchito malasha kaphatikizidwe mpweya woyamba, ndiyeno ntchito madzi ndi mpweya monoxide mu kaphatikizidwe mpweya monga zopangira kukonzekera ethylene glycol), ndi mphamvu kupanga mlandu oposa 30% ndipo zotsatira zake zidaposa matani 3 miliyoni.Mtengo wamafuta wakwera m'zaka ziwiri zapitazi, ndipo kupanga malasha ku ethylene glycol ku China kwakula kwambiri.Mu 2021, kupanga malasha ku ethylene glycol ku China kudzakula pafupifupi 50% pachaka.Monga China ili ndi mphamvu ya "malasha ochulukirapo, mafuta ochepa komanso mafuta ochepa", malasha ku ethylene glycol ndi chikhalidwe cha China ponena za kupezeka kwa ethylene glycol ku China.M'tsogolomu, malasha aku China ku ethylene glycol ali ndi kuthekera kwakukulu kwachitukuko.
2. Nafita ndi wofooka komanso wovuta kuwongolera
Kusowa kotayirira ndi kufunikira kunapangitsa kuti gawo la ethylene glycol lisagwire bwino ntchito, ndipo kupanga kwake kudakhalabe pamlingo woipa.Nthawi yomweyo, magwiridwe antchito ake a naphtha ndi ethylene amakhalanso aulesi, zomwe zimapangitsa kuti mtengo wa chithandizo cha ethylene glycol ukhale wofooka.
Pankhani ya msika wapadziko lonse wa ethylene glycol zopangira, kuphatikiza kwa naphtha kumakhala gawo lalikulu kwambiri, kutsatiridwa ndi gasi wachilengedwe ndi kupanga ethane kunja kwa nyanja, komanso kupanga malasha ku China.Kuphatikizika kwa Naphtha kunali njira yopangira zinthu zopindulitsa kwambiri, koma chaka chino, mtengo wamphamvu wamafuta ndikugwiritsa ntchito mofooka zidapangitsa kutayika kwathunthu mu unyolo wamakampani a olefin, mayunitsi ophwanyira ethylene adachepetsa kupanga m'dera lalikulu, komanso mtengo wamafuta amafuta a naphtha. kusiyana kamodzi analowa osiyanasiyana zoipa, Izi zikutanthauza kuti mankhwala mtengo ndi wotsika kuposa zipangizo, ndi kupanga ndi kutayika.Pofika kumapeto kwa Okutobala, kusiyana kwamitengo pakati pa naphtha ndi mafuta osapsa kunali kusinthasintha pafupifupi ziro.Kufooka kwa naphtha kumapangitsa ethylene glycol kusowa thandizo la mtengo.Choncho, pamene mtengo wa mafuta ukukwera ndi kutsika, naphtha imatsatira mtengo wa mafuta pansi, ndipo ethylene glycol imataya ndalama zothandizira.Izi ndizofunikiranso kuti mtengo wa ethylene glycol upitirire kufooka kuyambira gawo lachiwiri la chaka chino.
3. Mtengo wamakala wamphamvu sungathe kuthandizira ethylene glycol
Mzere wopanga malasha ndi njira yapadera yopangira ethylene glycol ku China.Pakali pano, mphamvu zoweta malasha zoweta zafika matani 8.65 miliyoni, mlandu 37% ya mphamvu okwana zoweta.Mtengo wa malasha amankhwala ndi wamphamvu kwambiri, ndipo wakhala ukugwira ntchito pa yuan/tani yoposa 1100 kwa zaka zambiri, ndipo wafika pa yuan 1300 pa toni kuyambira Seputembala.Kutayika kwa malasha ku ethylene glycol kumangoyerekeza kupitirira 1000 yuan/ton.Chifukwa magwero a ma syngas omwe amagwiritsidwa ntchito ndi gawo lililonse ndi osiyana, phindu lenileni la kupanga likhoza kuganiziridwa mozama.Komabe, malasha ku ethylene glycol akhala akutayika kuyambira gawo lachiwiri la chaka chino, ndipo kutayika kukupitirizabe kukula ndi kulimbikitsa mitengo ya malasha.Komabe, zomera zina zamafakitale za malasha zimagwiritsa ntchito mpweya wa coke oven tail gasi popanga, womwe ndi wobwezeretsanso zinyalala ndipo sukhudzidwa ndi mtengo wamalasha;Kuphatikiza apo, pali zida zina zothandizira zamabizinesi amalasha.Pokwera mitengo ya malasha, phindu la malasha kumtunda ndi lolemera, kotero kulolerana kwa kutsika kwa ethylene glycol kutayika kumatheka.Choncho, titha kuona kuti ngakhale phindu la malasha ku ethylene glycol ndi losauka chaka chino, gawo lake silimakhudzidwa kwambiri ndi kusinthasintha kwa phindu poyerekeza ndi zaka zapitazo.Chothandizira chapachaka chothandizira ndi zofunikira zina zokonzekera za unit zinakhazikika mu gawo lachitatu, zomwe zinapangitsa kuti kuchepa kwachangu kwa ntchito ya malasha ku ethylene glycol kutsika.Pazonse, kupatula kutsekedwa kwa mayunitsi angapo akunja opangira migodi chifukwa cha zovuta za phindu m'chaka, ntchito yamagulu a malasha imakhala yokhazikika chaka chino, ndi chithandizo chochepa cha ethylene glycol.
Kuyang'ana zamtsogolo, kuperewera kofooka ndi chiyembekezo chofuna kusungitsa mtengo wa ethylene glycol pansi pamavuto.Matani 600000 a matani 1.8 miliyoni ku Yulin, Shaanxi Coal Mine atumizidwa, ndipo matani otsala a 1.2 miliyoni akukonzekera kuti apangidwe mu gawo lachinayi.Kuphatikiza apo, polojekiti ya Jiutai 1 miliyoni ya matani a ethylene glycol yakhazikitsidwanso.M'tsogolomu, palinso kuyembekezera kuti Sanjiang 1 miliyoni ton MTO ndi ethylene glycol unit yothandizira Shenghong Petrochemical idzayikidwa pakupanga.Kuyambira kotala lachinayi mpaka theka loyamba la chaka chamawa, mphamvu yatsopano yoperekera ethylene glycol ikadali yayikulu.Kugwiritsa ntchito kopanda mphamvu kumapitilirabe kutsika msika wa olefin.Mtengo wotsika wa naphtha umapangitsa ethylene glycol kusowa thandizo la mtengo, ndipo mitengo yamoto yamalasha yam'nyumba imakhala yovuta kuti ikhale ndi zotsatira zazikulu pa ethylene glycol.Chiyembekezo cha mtengo wofooka ndi kupezeka ndi kufunikira kumapangitsa kuti mtengo wa ethylene glycol ukhale wotsika.
