Kwi-2022 isikhundla sokuveliswa kwe-eChina saseChina se-China se-China sifikelele kwi-49.33 yezigidi, sigqithile kwi-United States, siba ngumvelisi omkhulu we-United States, i-Ethylene ithathelwe ingqalelo njengophawu oluphambili ukumisela inqanaba lemveliso. Kulindelwe ukuba amandla angama-2025, eChina ye-China e-China e-Ethlone aya kudlula iitoni ezingama-70, eziya kuthi zihlangabezane nemfuno yasekhaya, okanye intsalela.

Umzi-mveliso we-ethylene yishishini lepetrochemical, kwaye i-akhawunti yayo ye-akhawunti engaphezulu kwe-75% yeemveliso zepetrochemical kwaye ihlale isikhundla esibalulekileyo kuqoqosho lwesizwe.

Bethylene, Propyne, Butadiene, Acetylene, Benzene, Eslene Oxide eziveliswa zizityalo ze-Ethylene, zizinto ezisisiseko zamandla amatsha kunye namasimi amatsha endalo. Ukongeza, iindleko zemveliso ze-ithylone eziveliswa ngamashishini amakhulu adibeneyo kunye nekhemikhali iphantsi. Xa kuthelekiswa namashishini okuhlaziya amanqanaba afanayo, ixabiso elongeziweyo leemveliso zemveliso edibeneyo kunye neShemikhali zinokunyuswa ngama-25% kwaye ukusetyenziswa kwamandla kunokuncitshiswa malunga ne-15%.

I-Polycarbonate, i-Lithium yebhetri, ifotoVoltaic Eat (i-Ethylene - i-vinyl acetate compolymer), i-binybone ye-olestomer), i-Polybodeni ye-Polyboner Ngokweenkcukacha-manani, kukho iintlobo ezili-18 ze-Ethylene Dowstream ezinxulumene namandla amatsha, izinto ezintsha kunye namanye amashishini omoya. Ngenxa yophuhliso olukhawulezileyo lwamandla amatsha kunye namashishini amatsha anje ngezithuthi zamandla amatsha, iifotovoltaic kunye ne-semicontuc kunye ne-semicondtaic kunye ne-semicondtaic kunye ne-semicondtaic kunye nemfuno yeemveliso ezintsha ezibonakalayo ziyanda.

I-Ethylene, njengeyona ndawo iphambili yomzi-mveliso wepetrochemical, inokuba sentsalela, iphawula ishishini lePetrochemical elijonge kwakhona i-reshuffical kunye nomahluko. Ayisiyo nje amashishini okhuphiswano aphelisa amashishini angasemva, amandla okhuphiswano aphelisa umthamo ongasemva, kodwa nokuzalwa nokufana nokuzalwa ngokutsha kwamashishini aphezulu e-Ethylene Dowstream Shin;

Iinkampani zentloko zinokuphinda zisebenze

I-Ethylene isenokuba sentsalela, inyanzela ukudityaniswa okudibeneyo kunye neekhemikhali zokudibanisa ukongeza i-chain, yandisa i-chain kwaye yomeleze i-chain ukuphucula ukhuphiswano lweyunithi. Ukuqala kwioyile ebuhlungu, kuyimfuneko ukwakha i-REAW YOKUFUNDA NGOKUGQIBELA. Ngalo lonke ixesha kukho ithemba lokuthengisa okanye iimveliso ezinomthamo othile wentengiso, umtya uya kutsalwa, okwazisa ukupheliswa kwabaphumeleleyo kunye nabaphumeleleyo kumzi-mveliso wekhemikhali. Imveliso kunye nepateni yeemveliso zekhemikhali zekhemikhali kunye neemveliso zekhemikhali ezilungileyo ziya kubhala ngotshintsho. Iintlobo ngeentlobo kunye nesikali ziya kuba zigxilwe ngakumbi, kwaye inani lamashishini liya kuncipha.

Izixhobo zonxibelelwano, iiselfowuni, izixhobo ezinxibeleleneyo kunye nabanye e-Eleclible kunye nobukrelekrele bezithuthi, indawo yokusebenza ye-Affiction, uqhuba ukukhula okukhawulezayo kwimfuno yezixhobo ezitsha zekhemikhali. Ezi zixhobo zintsha zekhemikhali kunye namashishini okukhokela amashishini anemilinganiselo yokukhula aya kuvela ngokukhawuleza, njengamandla amatsha ali-18 kunye neemveliso ezintsha zezinto ezibonakalayo ze-ethylene.

I-fan hongwei, usihlalo waseHengli Perochemicals, utshilo ukuba ungayigcina njani inzuzo eyomeleleyo yokhuphiswano kwaye ucofe iindawo ezintsha zenzuzo yenkqubo ye-chain yezamashishini yingxaki ekufuneka ijolise kuyo. Kuya kufuneka sinikele ngokupheleleyo kwiinzuzo ze-chain yecandelo eliphantsi, landisasaza i-chain yeshishini ejikeleze iimveliso ezihambahambayo, kwaye zazabalazela ukukhuthaza iimveliso ezizinzileyo ze-dowstream ukwakha i-chain yomimandla emitsha.

I-Kang hui i-Interbact ye-Hongli Petrochemical, inokuvelisa iMicron I-Lithim Sumer I-Limit Limit Line, i-Hong Petrochemical Inshorication I-Akhawunti ye-5DFDE, kunye ne-MLCCICATION SICE SCOCS, iNkqubo yeNdawo yeMiboniso yefilimu engaphezulu kwe-65% yemveliso yasekhaya.

Ukuthatha ukucocwa kunye nokudityaniswa kwemichiza njengeqonga lokwandisa ngokuthe nkqo nangokuthe nkqo, sandisa kwaye someleze iindawo ze-niche kunye nophuhliso oluhlanganisiweyo lweendawo ze-niche. Nje ukuba inkampani ingena kwimarike, inokungena kumashishini athembekileyo. Amashishini ayi-18 akhokelayo amandla amatsha kunye neemveliso ezintsha zezinto ezibonakalayo ezantsi kwe-e-ithylene zinokujamelana nobunini kwaye ziyeke ukuthengisa.

Ngapha koko, kwangoko, i-Shenghomicals isungule i-300,000 yeetoni / unyaka uEva usebenzisa iinzuzo ze-750,000 ye-2024, i-Shenghong Petrochemicals enkulu kakhulu ye-EVA.

I-China i-China i-China ekhoyo, inani leepaki kunye namashishini amaphondo aphambili aya kunciphisa ngokuthe ngcembe, i-shandong iipaki ezingama-80 ziya kunciphisa ngokuthe ngcembe, i-shandong ngaphezulu kweendawo zamashishini ezixineneyo ziya kukhutshwa isiqingatha. Kwinkampani, hayi awulunganga, kodwa abantu abakhuphisana nabo bomelele kakhulu.

"Kuya kusiba nzima 'ukunciphisa ioyile kunye nokwandisa ikhemistri

"Ukuncitshiswa kweoyile kunye nokunyuka kweekhemikhali" kube sisikhokelo senguqu ye-oyile yokucoca ioyile kunye nemveliso yemichiza. Isicwangciso senguqu ngoku ikakhulu sivelisa izixhobo ezisisiseko zekhemikhali ezifana ne-ethylene, i-proplene, i-proplene, i-butadiene, i-bebine, toulene kunye neXyyne. Ukusuka kwitrape yophuhliso lwangoku, i-Ethylene kunye ne-Ethylene isekhona igumbi lokuphuhlisa, lo gama i-ithylene isenokwentsalela, kwaye iya kuba nzima ngakumbi 'ukunciphisa ioyile kunye nokonyusa i-oyile ".

Okokuqala, kunzima ukukhetha iiprojekthi kunye neemveliso. Okokuqala, imfuno yentengiso kunye nomthamo wentengiso ziya kuba nzima ukukhetha iimveliso ngetekhnoloji yeqonga. Okwesibini, kukho imfuno yentengiso kunye nobungakanani beentengiso, ezinye iimveliso zixhomekeka ngokupheleleyo kwiimveliso ezingeniswayo, i-radiber ye-piber ye-wibber, i-sublbon ye-fiber, intamo enesiphelo, kwaye ezi mveliso zingalindelekanga ukuba zikwazise iiseti ze Itekhnoloji, kwaye inokunyusa rhoqo utyalomali kuphando nophuhliso.

Umzi mveliso wonke wokunciphisa ioyile kunye nokonyusa amachiza, kwaye ekugqibeleni ukhokele kubungakanani beemveliso zekhemikhali. Kwiminyaka yakutshanje, iprojekthi yokudibanisa kunye nekhemikhali ijolise 'ekunciphiseni ioyile kwaye inyuse i-chemistry ", kwaye amashishini akhoyo ahlaziyiweyo kunye nokunyusa i-chemistry" njengokuphuculwa. Kule minyaka mibini ukuya kwemithathu, i-China i-China's entsha yemichiza iphantse igqithe inani leshumi elidlulileyo. Umzi-mveliso wokucoca "yi-oyile kunye ne-oyile enyukayo. Emva kwencopho yokwakhiwa kwamandla, ishishini lonke linokuba ne-subserting kunye neemveliso zekhemikhali ezinamachiza, kwaye zinokungaphezulu kokungaphezulu kokungaphezulu kokungaphezulu kwexabiso.
