Ngo-2022, umthamo wokukhiqizwa kwe-Ethylene Production wafinyelela amathani ayizigidi ezingama-49.33, udlulise umkhiqizi omkhulu we-United States, abe ngumkhiqizi we-ethylene omkhulu emhlabeni, i-Ethylene ithathwa njengenkomba yokhiye ukunquma izinga lokukhiqiza imboni yemboni yamakhemikhali. Kulindelwe ukuthi ngo-2025, umthamo wokukhiqiza i-Ethylene Production wedlula amathani ayizigidi ezingama-70, azohlangabezana nesidingo sasekhaya, noma ngisho nokuningi okusalayo.

Umkhakha we-ethylene ungumgogodla wemboni ye-petrochemical, nemikhiqizo yawo i-akhawunti yayo ngaphezulu kwama-75% wemikhiqizo ye-petrochemical futhi ahlale isikhundla esibalulekile emnothweni wezwe lonke.

I-Ethylene, i-propylene, i-acetylene, i-acetylene, i-acetylene, i-toluene, i-xylene, i-ethylele oxide, i-ethylene glycol, njll. Kukhiqizwe izitshalo ze-ethylene, ziyizinto zokusetshenziswa ezisisekelo zamandla amasha nezinkundla ezintsha ezibonakalayo. Ngaphezu kwalokho, izindleko zokukhiqiza ze-ethylene ezikhiqizwe ngamabhizinisi amakhulu ahlangene namakhemikhali aphansi. Uma kuqhathaniswa namabhizinisi okucwengeka kwesilinganiso esifanayo, inani elingeziwe lemikhiqizo yamabhizinisi ahlanganisiwe wokucwengisa namakhemikhali angakhushulwa ukusetshenziswa kwama-25% kanye namandla angancishiswa cishe ngo-15%.

I-Polycarbonate, i-Lithium Battery Surparer, i-Photovoltaic EVA (Ethylene - I-Vinyl Acetate Copolymer) ingenziwa nge-ethylene, i-caryoofem elastomer), i-choobonate, i-DIMETYL Carbonate), isisindo se-polyethylene (UHMWPE) nezinye Imikhiqizo emisha yezinto ezibonakalayo. Ngokusho kwezibalo, kunezinhlobo eziyi-18 zemikhiqizo ye-ethylene downstream ephathelene namandla amasha, izinto ezintsha nezinye izimboni ezinomoya. Ngenxa yokuthuthukiswa okusheshayo kwamandla amasha nezimboni ezintsha ezifana nezimoto ezintsha zamandla, i-Photovoltaic kanye ne-semiconductors, isidingo semikhiqizo emisha yezinto ezibonakalayo siyanda.

I-Ethylene, njengomgogodla wemboni ye-petrochemical, kungenzeka ukuthi isesandleni esengeziwe, ukumaka imboni ye-petrochemical ebheke ukubuyisela kabusha nokuhlukanisa. Hhayi amabhizinisi ancintisanayo kuphela aqeda amabhizinisi angemuva, amandla athuthukile aqeda amandla angemuva, kodwa futhi nokushona phansi nokuzalwa kabusha kwamabhizinisi aholayo e-Ethylene Town Chain Segen Tegstream.

Izinkampani zezinhloko zingahlehlisa kabusha

I-Ethylene ingahle ibe sekwenyusa, iphoqelela ukucophelela okuhlanganisiwe kanye namayunithi amakhemikhali ukuze iqhubeke ngokungezelela iketanga, ukunweba iketanga bese liqinisa iketane ukuze lithuthukise ukuncintisana kweyunithi. Kusukela kumafutha aluhlaza, kuyadingeka ukwakha inzuzo eluhlaza yokuhlanganiswa. Uma nje kunamathemba emakethe noma imikhiqizo enomthamo othile wemakethe, kuzodonswa umugqa, okuzodonswa futhi okusheshisa ukuqedwa kokuwina kanye nokwehluleka kuyo yonke imboni yamakhemikhali. Ukukhiqizwa kanye nephethini yemikhiqizo yamakhemikhali amaningi nemikhiqizo emihle yamakhemikhali kuzoletha izinguquko. Izinhlobo zokukhiqiza nezikali zizobe zigxile kakhulu, futhi inani lamabhizinisi lizokwehla kancane kancane.

Imishini Yezokuxhumana, amaselula, amadivaysi agqokekayo kanye nezinye izinhlelo ze-elekthronikhi zabathengi, ubuhlakani bezimoto, amasimu e-apply prounce asekhaya akhula ngokushesha, eshayela ukukhula okusheshayo okufunwayo kwezinto ezintsha zamakhemikhali. Lezi zinto ezintsha zamakhemikhali kanye namabhizinisi aholayo ama-monomer anomkhuba wokukhula azovela ngokushesha, njengamandla amasha ayi-18 nemikhiqizo emisha yezinto ezibonakalayo phansi kwe-ethylene.

UFan Hongwei, uSihlalo weHengli Petrochemicals, uthe ukuzogcina kanjani izinzuzo eziqinile zokuncintisana futhi uthephe amaphuzu amaningi wenzuzo ezintsha kuHlelo Lokusebenza Kwezimboni kudinga ukugxila kuwo. Kufanele sinikeze ukudlala okugcwele kwezinzuzo ze-Upstream Imboni Yezimboni, zinwebe futhi zijulise i-chain embonini ezungeze imikhiqizo emisha yokuncintisana ukudala izinzuzo ezintsha zokuncintisana, futhi zilwele ukukhuthaza ukwanda okuqhubekayo kwemikhiqizo emihle yamakhemikhali ukwakha i-towstream.

I-Kang Hui entsha, umxhaso weHengli Petrochemical, angakhiqiza i-silicon engu-12 ye-silico ekhipha i-lithium Ukuvikelwa kwe-Lithium

Ukuhlanganisa ukucolisiswa kanye nokuhlanganiswa kwamakhemikhali njengeplatifomu yokunweba ngokuqondile nangokuqondile, siyanda futhi siqinisa izindawo ze-niche futhi sakha ukuthuthukiswa okuhlanganisiwe kwezindawo ze-niche. Lapho inkampani ingena emakethe, ingangena emabhizinisini aholayo. Amabhizinisi ayi-18 aholayo wamandla amasha nemikhiqizo emisha yezinto ezibonakalayo ezansi komfula ongabhekana noshintsho lobunikazi futhi ashiye imakethe.

Eqinisweni, ekuqaleni kuka-2017, ama-shenghong petrochemicals aqala amathani angama-300,000 amathani / i-EVA esebenzisa izinzuzo zalo lonke imboni, ukuphela kuka-2024 kuzofakwa kancane kancane amathani angu-2050,000 e-EVA, ukuze akhiqizwe ngo-2025, ngo Ngemuva kwalokho, ama-penghong petrochemicals azoba yisisekelo esikhulu kunazo zonke emhlabeni.

Ukuhlaselwa kwamakhemikhali kwamakhemikhali e-China, inani lamapaki namabhizinisi ezifundazweni ezinkulu zamakhemikhali azophinde anciphise, amapaki amakhemikhali angaphezu kwama-80 azoncipha kancane kancane, Okwenkampani, hhayi ukuthi awumuhle, kepha izimbangi zakho ziqinile kakhulu.

"Kuba nzima ngokwengeziwe 'ukunciphisa uwoyela nokwandisa i-chemistry

"Ukwehliswa kwamafutha kanye nokwanda kwamakhemikhali" sekuphenduke ukuqondiswa kwezinguquko kowoyela wasekhaya wokucwengwa kwamafutha kanye nemboni yamakhemikhali. Uhlelo lokuguqulwa kwamanje lokufumbathisa lukhiqiza ikakhulukazi izinto eziyisisekelo zokusetshenziswa kwamakhemikhali ezifana ne-ethylene, i-propylene, i-bateneene, i-benzene, i-toluene ne-xylene. Ukusuka enkambisweni yentuthuko yamanje, i-ethylene ne-propelene isenethuba elithile lokuthuthuka, kanti i-ethylene ingahle ibe sekwenyusa, futhi kuzoba nzima ngokwengeziwe "ukunciphisa uwoyela nokwandisa amakhemikhali futhi kukhuphule amakhemikhe futhi kwandise amakhemikhali".

Okokuqala, kunzima ukukhetha amaphrojekthi nemikhiqizo. Okokuqala, ukufunwa kwemakethe kanye nemakethe yemakethe kuya ngokuya kunzima ukukhetha imikhiqizo nobuchwepheshe obuvuthiwe. Okwesibili, kunezidingo zemakethe kanye nemakethe yemakethe, eminye imikhiqizo ithembele ngokuphelele kwimikhiqizo engenisiwe, ayina kahle ubuchwepheshe bokukhiqiza, njengenjoloba yokwenziwa ephezulu, imicu ye-high-end zokwenziwa kanye nama-monometic - I-Carbon fiber, amapulasithi wobunjiniyela, amakhemikhali ahlanzeke nge-elekthronikhi aphezulu, njll. Yonke le mikhiqizo ibhekene nenkinga ye- "ntamo", futhi le mikhiqizo akunakukwazi ukwengeza ukutshalwa kwezimali okuphelele kocwaningo futhi ukuthuthukiswa.

Yonke imboni ukunciphisa uwoyela nokwandisa amakhemikhali, futhi ekugcineni kuholele kumandla amaningi emikhiqizo yamakhemikhali. Eminyakeni yamuva, iphrojekthi yokuhlanganiswa kwamakhemikhali kanye nokucwengeka kwamakhemikhali ihlose "ukunciphisa uwoyela nokwandisa i-chemistry", futhi amabhizinisi akhona namakhemikhali aphinda athathe u-chemistry futhi athuthukise i-Chemistry "njengokuthuthuka. Eminyakeni emibili kuya kwemithathu, umthamo omusha wamakhemikhali waseChina ucishe wadlula isamba seminyaka eyishumi edlule. Yonke imboni yokucwengisisa "inciphisa uwoyela kanye nokwanda kwamakhemikhali. Ngemuva kwenani eliphakeme lokwakhiwa kwamandla amakhemikhali, wonke imboni kungenzeka ibe nokusalela noma okuphezulu kakhulu. Izinto eziningi zamakhemikhali amasha nemikhiqizo emihle yamakhemikhali inezimakethe ezincane, futhi inqobo nje uma kukhona ukuphumelela kobuchwepheshe, kuzoba nokushesha, okuholele ekunciphiseni ukweqisa kanye nokulahleka kwenzuzo, futhi ngisho nasempini yentengo emincane.
