1, Amagqabantshintshi ngemeko yokusebenza ngokubanzi

Ngo-2024, intsebenziswano iyonke ye-China ishishini lekhemikhali alilunganga phantsi kwempembelelo yendawo ngokubanzi. Inqanaba lenzuzo yamashishini emveliso liye lancipha, imiyalelo yamashishini eRhwebo inciphile, kwaye uxinzelelo lwenkqubo yentengiso luye lonyuka kakhulu. Iinkampani ezininzi zizabalazela ukuphononongwa kwiimarike zaphesheya ukuze zifune amathuba amatsha ophuhliso, kodwa imeko yangoku yemakethi inobuthathaka kwaye ayiboneleli ngamandla ongezelelweyo okukhula. Lilonke, ishishini lekhemikhali laseTshayina lijamelene nemiceli mngeni.

2, Uhlalutyo lwenkqubo yenzuzo yeekhemikhali zobuninzi

Ukuze ufumane ukuqonda okunzulu kokusebenza kwemakethi yekhemikhali yaseTshayina, kuqhutywa iindidi zeekhemikhali zobuninzi, kunye nomzi mveliso ophakathi kwenqanaba lomtshato kunye nenqanaba lonyaka ukuya kuthi ga ngoSeptemba ukuya ku-Septemba 2024 bahlaziywa .

Ukuhanjiswa kwenzuzo kunye nelahleko yokwenza iimveliso: phakathi kweentlobo ezingama-50 zeekhemikhali zobuninzi, kukho iimveliso ezingama-31 kwimo yenzuzo, inika ingxelo malunga ne-62%; Kukho iimveliso ezili-19 ekuphuculeni ilahleko, inika ingxelo malunga ne-38%. Oku kubonisa ukuba nangona uninzi lweemveliso zisenzuzo, umyinge wokulahleka kokwenza iimveliso zingenakuhoywa.

Unyaka nonyaka oguqukayo kwiNzuzo yeNzuzo: Ukusuka kwimbono yeqondo lokutshintsha leminyaka emininzi, umdaniso wenzuzo we-32 iimveliso ezingama-32 zehlile, inika ingxelo nge-64%; Inzuzo yenzuzo yeemveliso ezili-18 kuphela ezandlala ngonyaka-onxunguphalo, i-accounting nge-36%. Oku kubonisa ukuba imeko iyonke kulo nyaka ibaluleke kakhulu kunonyaka ophelileyo, kwaye nangona imibutho yenzuzo yezona mveliso ihleli inethemba, iye ebonisa ukusebenza kakuhle.

I-3, ukuhanjiswa kwamanqanaba okuphawulwa kwenkqubo

Umda wenzuzo weemveliso ezinzuzo: Inqanaba lemihlaba yenzuzo yeemveliso ezinzuzo igxilwe kuluhlu lwe-10%, enenani elincinci leemveliso ezinenzuzo ye-10%. Oku kubonisa ukuba nangona ishishini lentsebenzo iyonke ye-Chical Chemical liyingenelo, inqanaba lengeniso aliphezulu. Ukujonga izinto ezinjengeendleko zemali, iindleko zolawulo, ukuhla kwexabiso, njl njl.

Umda wenzuzo esenza iimveliso: Ukulahleka kokwenza iichemicals, uninzi lwazo lujolise ngaphakathi kuluhlu lwe-10% okanye ngaphantsi. Ukuba ishishini leli projekthi ehlanganisiweyo kwaye inezinto zayo zezinto eziluhlaza, emva koko iimveliso ezinelahleko nje zisenokuhlanganisa inzuzo.

4, Thelekisa imeko yenzuzo ye-chain yezamashishini

Umzobo 4 uthelekiso lwenzuzo yenzuzo ye-China e-China e-China kwi-2024

Ngokusekwe kwinqanaba eliphakathi lenzuzo yenkqubo yeshishini leShishini apho ingaba yiphi imveliso engama-50, singazitsalela ezi zigqibo zilandelayo:

Iimveliso eziphezulu zenzuzo: ifilimu ye-PVB, i-octanol, i-trimellitic anehydride, iBanga lokukhetha i-COC kunye nezinye iimveliso ezibonakalisa ingeniso eyomeleleyo, ephakathi kwi-30% yenzuzo yenzuzo engaphezu kwe-30%. Ezi mveliso zihlala zinepropathi ekhethekileyo okanye zibekwe kwindawo esezantsi kwi-suin yeshishini, kunye nokhuphiswano olubuthathaka kunye nenzuzo enobungozi.

Ukuphulukana nokwenza iimveliso: I-Petroleum to yelene Glycol, i-Hydrogenic Anhydride, Ethyyne kunye nezinye iimveliso zibonise ilahleko enkulu, kunye nenqanaba eliphezulu lokulahleka ngaphezulu kwe-35%. I-Ethylene, njengemveliso ephambili kwishishini lekhemikhali, ilahleko yalo ngokungathanga ngqo ibonisa intsebenzo engekho mthethweni ye-China yeChical.

Ukusebenza kwekhonkco lemizi-mveliso: Intsebenzo iyonke ye-C2 kunye ne-C4 yemizi-mveliso ilungile, kunye nenani elikhulu leemveliso ezinzuzo. Oku ikakhulu kungenxa yokwehla kweendleko zemveliso ezihamba phantsi okubangelwa sisixhobo sokuphela kwe-vink ye-chain, kwaye inzuzo idluliselwa ezantsi kwi-chain yemveliso. Nangona kunjalo, ukwenziwa kokuphela kwezinto ezingafunekiyo zingamahlwempu.

I-5, imeko egqithisileyo yotshintsho lonyaka ukuya kwi-inzuzo yenzuzo

I-N-B-Bleane esekwe kwi-anhydride ye-Anhydride: Inzuzo yayo yenzuzo inotshintsho olukhulu lweminyaka ubudala, ukutshintsha ukusuka kwi-Inzuzo ephantsi kwi-2023 kwilahleko malunga ne-3% ukusuka ngoJanuwari ukuya ku-Septemba ukuya ku-Septemba ukuya ku-Septemba ukuya ku-Septemba ukuya ku-Septemba. -Ukuhla kwexabiso lentengo ye-annehydride, ngelixa ixabiso lezinto ezibukhali ze-N-Butane inyuke, ikhokelela kwiindleko ezandayo kunye nexabiso lokuphuma.

I-Benzoic Anhydride: Inzuzo yayo yenzuzo inyuke kakhulu i-900% yonyaka-unyaka wonke, iyenza eyona mveliso iguqukayo kwimakethi yenzuzo engu-2024. Ukurhoxiswa kwe-Ineos kwintengiso yehlabathi ye-PHTHAY Anhydride.

Ithemba lexesha elizayo

Kwi-2024, ishishini lemichiza lase China lifumene ukwehlisa unyaka wonke kunye nokuncipha okukhulu kwengeniso emva kokufumana uxinzelelo lweendleko kunye nokwehla kumaziko amaxabiso emveliso. Ngokuchasene ne-Backdrop yamaxabiso olwelo obucacileyo, umzi-mveliso wokucoca ubonile ukubuyela kwimeko yesiqhelo kwinzuzo, kodwa izinga lokukhula kwemfuno licothise kakhulu. Kumzi-mveliso weqela lekhemikhali, ukungqubana kwe-homoning uphononongo kubonakala ngakumbi, kwaye indawo yokubonelela kunye nendawo yokufuna iyaqhubeka ukonakala.

Kulindelwe ukuba ishishini lekhemikhali lamaTshayina lisajamelana noxinzelelo oluthile kwisiqingatha sesibini se-2024 nangaphakathi kwe-2025, kwaye uhlengahlengiso lwesakhiwo semveliso siza kuqhubeka ukhula. Izaphulelo kwiitekhnoloji eziphambili kunye neemveliso ezintsha kulindeleke ukuba ziphuculwe kwimveliso yemveliso kwaye zikhuthaze ukuphuculwa kweniso ephezulu kakhulu yeemveliso zokuphela. Kwixesha elizayo, ishishini lemichiza lemichiza yase-China kufuneka yenze ngakumbi iinzame zobuchwephesha, uhlengahlengiso lwesakhiwo, kunye nophuhliso lwentengiso ukujongana nemiceli mngeni yangoku nezamva.
