Pofika mu 2023, msika wa butadiene wa m'dziko muno wakwera kwambiri, mtengo wamsika wakwera ndi 22.71%, kukula kwa chaka ndi chaka kwa 44.76%, zomwe zapangitsa kuti pakhale chiyambi chabwino. Omwe akutenga nawo mbali pamsika akukhulupirira kuti msika wa butadiene wa 2023 udzakhala wovuta, msika ndi woyenera kuyembekezera, nthawi yomweyo nthawi yonse yogwirira ntchito ya msika wa butadiene wa m'dziko muno kapena idzakhala yokwera pang'ono kuposa 2022, ntchito yonse yayikulu.
Kusakhazikika kwakukulu kwa msika
Katswiri wa Jin Lianchuang, Zhang Xiuping, adati makampaniwa akhala akukayikira msika wa butadiene mu Januwale chifukwa cha momwe Shenghong Refining ndi fakitale ya mankhwala zimakhudzira. Komabe, kukonza mafakitale a butadiene ku Zhejiang Petrochemical ndi Zhenhai Refining ndi fakitale ya mankhwala mu February ndi March kwakweza pang'onopang'ono momwe msika umagwirira ntchito. Kuphatikiza apo, kufunikira kwa mafakitale a acrylonitrile — butadiene — styrene copolymer (ABS) kukukula pang'onopang'ono. Msika ukufufuza kwambiri.
Ngakhale kuti gawo la butadiene mu Gawo Lachiwiri la Zhejiang Petrochemical likuyembekezeka kutsekedwa kuti likonzedwe pakati pa mwezi wa February, ndipo fakitale ya Zhenhai Refining and Chemical ikuyembekezekanso kukonzedwanso kumapeto kwa mwezi wa February, fakitale ya Hainan Refining ndi Chemical Plant ndi petrochina Guangdong Petrochemical ikuyembekezeka kuyamba kugwira ntchito mu February. Mothandizidwa ndi mphamvu zonse, kupanga kwa butadiene kukuyembekezeka kukhala kokhazikika koma osati kosinthasintha, ndipo mtengo wamsika ukuyembekezeka kukhalabe wokwera.
Poganizira za kutulutsidwa kwa mphamvu ya bifienne mu 2023, pakhoza kukhala matani 1.04 miliyoni a mphamvu zatsopano zomwe zatulutsidwa chaka chonse, koma kuchedwa kwa kukhazikitsa kwina sikungathetsedwe. Nthawi yomweyo, mafakitale ambiri atsopano omwe amayenera kuyikidwa kumapeto kwa chaka chatha achedwetsedwa mpaka theka loyamba la chaka chino. Kuphatikiza pa Shenghong Refining ndi Chemical, mafakitale ena a butadiene monga Dongming Petrochemical akuyembekezekanso kuyamba kugwira ntchito. Mu theka loyamba la chaka, omwe akhudzidwa ndi kutulutsidwa kwakukulu kwa mphamvu zatsopano zopangira, kupezeka kwa butadiene kudzachepa pang'onopang'ono, msika kapena kuwonetsa kutsegulidwa kwakukulu.
Zikuyembekezeka kuti zida zatsopano zochepa za butadiene zidzayamba kupangidwa mu theka lachiwiri la chaka, ndipo zikuyembekezeka kuti zida zatsopano zotsatizana zidzayamba kupangidwa. Kuwonjezeka kwa kufunikira kudzakhala kwakukulu kuposa kuwonjezeka kwa kupezeka, ndipo mkhalidwe wovuta wa kupezeka pamsika upitirira.
Kuphatikiza apo, ndi kukonza bwino ndi kusintha kwa mfundo za mliriwu komanso chiyembekezo chowonjezeka cha kuchira kwachuma, kufunikira konse kwa anthu otsala m'dziko muno mu theka lachiwiri la chaka kungakwere poyerekeza ndi theka loyamba la chaka, ndipo chithandizo chamitengo kumbali ya kufunikira chikukweranso poyerekeza ndi theka loyamba la chaka. Mitengo yonse ya butadiene ngati zinthu zopangira ndi yayikulu kuposa theka loyamba la chaka.
Mtengo wa zipangizo zopangira ndi wovuta kutsika
Monga chinthu chopangira miyala yamtengo wapatali, monga zinthu zopangira butadiene, chinathandizidwa ndi kukula kwa kufunikira mu 2022, ndipo kupanga mafuta a ubongo wa miyala kunapitilira kukula chaka chonse. Malinga ndi deta yochokera ku National Bureau of Statistics, kutulutsa mafuta a ubongo wa miyala m'dziko langa mu 2022 kunali matani 54.78 miliyoni, kuwonjezeka kwa 10.51% kuposa chaka chatha; kuchuluka kwa mafuta a ubongo wa miyala omwe amatumizidwa kunja kunali matani 9.26 miliyoni, ndipo kugwiritsa ntchito mafuta a ubongo wa miyala kunali matani 63.99 miliyoni a matani 63.99 miliyoni. , Kuwonjezeka ndi 13.21% kuposa chaka chatha.
Mu 2023, pamene mliriwu ukutha pang'onopang'ono, mfundo zake zili bwino, chuma chayamba kuchira pang'onopang'ono, kuchuluka kwa ntchito zamafuta m'makampani opanga mafuta kudzawonjezeka, ndipo kufunikira kwa mafuta m'malo osungira mafuta kudzawonjezeka. Zikuyembekezeka kuti vutoli lipitirira mpaka kotala lachitatu. Pofika kotala lachinayi, malo opangira mafuta m'malo osungira mafuta adayamba kugwiritsidwa ntchito nthawi zonse, ndipo ntchito yomanga nyumbayo idachepa. Kufunika kwa mafuta ndi mafuta kunali pachiwopsezo chotsika.
Ponseponse, pamene fakitale yoyeretsera mafuta inalowa mu nthawi yokonza pakati mu kotala lachiwiri, mafuta a petroleum anachepa ndipo anathandizira kukwera kwa msika. Komabe, chifukwa cha kuchepa kwa kukula kwachuma padziko lonse komanso kufunikira kosakwanira, kukwera kwa mafutawo kunali kochepa, ndipo mtengo ukhoza kusinthidwa mtengo ukakhala wokwera. Kotala lachitatu linali pachimake pa maulendo achikhalidwe. Pa siteji iyi, mitengo ya mafuta osakonzedwa inabwerera pang'onopang'ono pamlingo woyenera. Phindu la chipangizo chosweka linakwera, ntchito yamsika inakwera, ndipo mtengo wa zipangizo zopangira unali wosavuta kufika pansi. Mu kotala lachinayi, msika wa petrochemical udzalowa mu nthawi yachikhalidwe yogwiritsidwa ntchito nthawi ya tchuthi, kufunikira kwatsika, ndipo mtengo wa mafuta a ubongo wa miyala udzatsikanso.
Malinga ndi makampani oyeretsera, ntchito yomanga mofulumira ya Yulong Island Refining Project ikukonzekera kuyikidwa mu kupanga kumapeto kwa chaka cha 2023. Gawo lachiwiri la Hainan Petrochemical Hainan Refining and Chemical, Zhenhai Refinery Phase I ndi CNOOC Petrochemical Plan linayang'aniridwa kuyambira 2023 mpaka 2024. Kukula kwa mafuta opepuka a mankhwala mosakayikira kuli kopindulitsa pamsika wamafuta, kotero kumathandizira kutsika kwa madzi kuphatikizapo butadiene pankhani ya mtengo.
Kuwonjezeka kwa kufunikira kwa madzi otsika
Kulowa mu 2023, mphamvu ya mfundo zabwino monga msonkho wogulira malo osungiramo zinthu za butadiene inakula pang'ono, ndipo makampani opanga rabara anakonzedwa mwachangu. Nthawi yomweyo, kukonza mosalekeza njira zopewera mliri wa dziko lonse kunabweretsanso zabwino zina pamsika wa rabara. Kuwonjezeka kwa kufunikira kwa zinthu zapansi panthaka panthawi ya tchuthi cha Spring Festival, komanso kutsika kwa butadiene, kukuyembekezeka kulowa mumsika kumayambiriro kwa 2023, ndipo kufunikira kwa butadiene kudzawonjezeka kwambiri.
Malinga ndi momwe mphamvu ya mphira ya butadiebenbenbenbenbenbenbenbal imatulutsidwira mu 2023, mphamvu ya mphira ya butadiebenbenbenbenbenbenbal ili ndi voliyumu yochepa, yomwe ndi matani 40,000 okha pachaka; capsule yatsopano ya capsule ili ndi matani 273,000; msika wa polypropylene ndi chunyrene -butadiene -lyzyrene convergence Mphamvu yopangira ndi matani 150,000 pachaka; ABS yawonjezera matani 444,900 pachaka, ndipo mphamvu yopangira yatsopano ya guluu wa Tinto ndi matani 50,000 pachaka; Sikovuta kuwona kuti chipangizo chatsopanochi chimayikidwa nthawi zonse popanga, ndipo kufunikira kwapansi kukuyembekezeka kuwonjezeka kwambiri. Ngati mphamvu yopangira yomwe ili pamwambapa itulutsidwa panthawi yake, mosakayikira ndi phindu lalikulu pamsika wa butadiene.
Kuphatikiza apo, pamene mfundo zopewera miliri zomwe zilipo pano zikupitilira kukonzedwa, zotsatira za miliri pa zinthu zotumizidwa kunja ndi zotumizidwa kunja zidzachepa pang'onopang'ono mtsogolo. Poyembekezera chaka cha 2023, kuchuluka kwa butadiene kudzidalira kudzawonjezeka, kuchuluka kwa zinthu zotumizidwa kunja kudzapitirira kuchepa, koma kubwezeretsa kufunikira kwa zinthu zakunja kudzathandiza kuchuluka kwa butadiene kutumiza kunja kuchuluke. Pofuna kulinganiza bwino kuchuluka kwa zinthu zomwe zikuperekedwa pamsika wamkati ndi momwe zinthu zikufunidwira, kuwonjezera kuchuluka kwa zinthu zotumizidwa kunja kungakhale cholinga cha makampani opanga butadiene m'nyumba.
