Izintengo zikawoyela we-WTI ziyaqhubeka nokunyuka cishe ngama-dollar angama-45, kodwa ukuguquguquka kwakamuva maphakathi namandla adonsela phansi kusobala. Ukunikezwa okunyukile kweSaudi Arabia ngezimakethe zase-Asia ngemuva komhlangano we-Opec kubonise ithemba layo mayelana nesidingo semakethe.
Umphathintambo kaTrump udlulise icala emthethwandaba weSupreme Court ngemva kokuba ubufakazi obutsha buveze ukuthi kube lezinkinga zokubala okhethweni lanxa kwaguquka amandla ngemva kokhetho lwase-US. Uhlelo losizo lwezomnotho lwase-us lwalolu bhubhane lusadingidwa futhi, futhi imakethe ibheke ngabomvu umphumela.
Umqedazwe wembulunga yonke usabhebhetheka. Kube nezindaba ezinhle nezimbi ngaphambili komuthi wokugoma, futhi sekukonke, usuku lokuqalisa luyasondela.
Ukuthunyelwa kwe-China ngoNovemba (ngokwemibandela ye-DOLLAR) kukhuphuke ngo-21.1% kunonyaka odlule, okulindeleke ukuthi kukhuphuke ngo-9.5%, uma kuqhathaniswa no-11.4% kusukela onyakeni odlule, kanti ukuthengwa kwamanye amazwe kwakukhuphuke ngo-4.5% kusukela ngonyaka odlule, okulindeleke ukuthi kukhuphuke ngo-4.3% ngonyaka ngaphambili; Imali enqwabelene yokuhweba ifinyelele irekhodi eliphezulu lama-dollar ayizigidi eziyizinkulungwane ezingama-75.42, isuka ku-$58.44 billion. Ngokwemigomo ye-yuan, ukuthunyelwa kwempahla kwamanye amazwe kukhuphuke ngamaphesenti angu-14.9, kusuka kumaphesenti angu-7.6.
Isibikezelo semakethe samanye amakhemikhali:
1. Isibikezelo: Inani le-methanol ekusatshalalisweni kwechweba lenyuke kakhulu ngempelasonto edlule. Uhlu lwabakhiqizi ezindaweni zokukhiqiza ezisenyakatho luphansi futhi izinga lokusebenza lilonke alishintshi kakhulu. Uma zingekho izinto ezinkulu ezinhle, kulindeleke ukuthi i-methanol isazocutshungulwa ngokuyinhloko kuleli sonto.
2. Isibikezelo: i-toluene, i-xylene plant yasekhaya iqala phansi, isidingo sisonke sibuthakathaka. Izimpahla zamachweba ziyaqhubeka nokuwa. Ukuguquguquka kwentengo kawoyela kunamandla. Kulindelwe kuleli sonto i-toluene yasekhaya, ukushaqeka kwemakethe ye-xylene kunamandla kancane.
3. Isibikezelo: IZINGA lokusebenza kwabakhiqizi be-PVC liyathuthukiswa, kodwa i-oda langaphambilini alikaqedwa, futhi inani lezindawo ezitholakala emakethe lincane uma kuqhathaniswa. Enyakatho, ngenxa yokuvikelwa kwemvelo nezinye izizathu, isidingo esingaphansi komfula sinciphe kancane. Indawo yokuthengisa engaphansi komfula ishayisana ngamanani aphezulu kodwa idinga nje ukuzinza. Ekupheleni kwesonto eledlule, i-rally yemakethe yemali yehla, imakethe kulindeleke ukuthi iqhubeke nokuguquguquka okukhulu kwaleli sonto, futhi kudingeka uqaphele ukuthi inkontileka yekusasa likaJanuwari isesengozini yokuguquguquka okukhulu.
4. Isibikezelo: Ngesonto eledlule, ukunikezwa kwe-acrylic acid ne-ester kuqinile futhi kuhlobene nezinto ezingavuthiwe ezikhuphuka ngaphansi kwezindaba ezinhle ukuze ziqhubeke ziqina. Okwamanje, ukunikezwa kwendawo kusaqinile, abakhiqizi ngeke behlise intengo, kudingeka nje ukulandelela isimo esingezansi komfula silungile. I-Acrylic acid ne-ester kulindeleke ukuthi imakethe yendawo yaleli sonto iqhubeke nokusebenza okuqinile kokuqeda.
5. Isibikezelo: Amanani entengo ye-maleic anhydride ehle kakhulu futhi ngokushesha ngesonto eledlule, okuphinde kwaveza isimo se-roller coaster. Ngenxa yokulindela kwesidingo esiqinile esingaphansi komfula, abakhiqizi bama-anhydride bamaleic banepuleti lokuvala ukuze baphakamise isenzo. Lo mbuthano kulindeleke ukuthi uqhubeke kuleli sonto.
6, ukuvalwa kokuhluleka kwemishini yakwamanye amazwe, kuhambisana nokwesekwa okuqinile kwezindleko, imakethe ye-styrene yamukele ukuphinda kuphindwe ekuqaleni kwesonto. Kodwa-ke, amayunithi asekhaya ekukhiqizeni, futhi isidingo esilandelayo sibuthakathaka, kulinganiselwa ukuthi imakethe ye-styrene izokhawulelwa esikhathini esifushane.
7. Ukuntuleka kokuxhumana phakathi kokunikezwa kanye nesidingo, kulinganiselwa ukuthi imakethe ye-acetone izoba nendawo encane yokukhuphuka kwesikhashana.
8. Kulinganiselwa ukuthi imakethe ye-DOP ingase yehle esikhathini esifushane ngenxa yokukhululwa kwezindleko kanye nesidingo esintengayo somfula.
9, ithuba lenhlanhla uma singekho isikhuthazo esikhulu esihle, linganisela ukukhuphuka kwesikhashana kwemakethe ye-phthalic anhydride kunzima kakhulu.
10. Ngokusekelwe esimeni esintekenteke sokunikezwa kwempahla nesidingo, kulinganiselwa ukuthi imakethe ye-MMA ingase iguquguquke ebangeni elincane esikhathini esifushane.
11. Ukusekelwa kwezindleko okuqinile, kodwa ukunikezwa kwasekhaya kulindeleke ukuthi kukhuphuke. Kulinganiselwa ukuthi esikhathini esifushane, imakethe ye-phenol ingase ibhekane kakhulu nokushaqeka.
I-12, i-periphery enhle, ukushaqeka kwemakethe yendawo ye-PTA ngesonto eledlule kuqinile. Nokho, ngenxa yezisekelo ezibuthakathaka uma kuqhathaniswa, kulinganiselwa ukuthi imakethe ye-PTA izonqunyelwa esikhathini esifushane.
13, ukwesekwa kwezindleko kunamandla, kodwa indima yokwehla komfula ijwayelekile, kulinganiselwa ukuthi imakethe ye-benzene emsulwa esikhathini esifushane noma izoba yinhlanganisela eqinile.
14. Uhlangothi lokuhlinzeka lunikeza okuthile okuhle, kodwa ukuntuleka kokubambisana okuphumelelayo nesidingo, kulinganiselwa ukuthi imakethe ye-tianjiao izonyakaziswa kakhulu esikhathini esifushane, inake isiqondiso sezici ze-peripheral.
Ngesonto eledlule, imakethe ye-acetic yasekhaya iqhubekile nokukhuphuka. Njengamanje, imboni isivele iqinile ekulethweni, kuhlanganiswe nokuvalwa okungalindelekile kwesitshalo se-BP e-Nanjing, uhlangothi lokuhlinzeka luqiniswa nakakhulu. Kodwa-ke, ngenxa yokukhuphuka okusheshayo kwentengo yemakethe kanye nokumelana okuqinile phansi komfula, kulindeleke ukuthi imakethe ingase yehlise leli sonto uma kuqhathaniswa nesonto eledlule.
16. Imakethe ye-butanone yasekhaya ikhuphuke kakhulu ngesonto eledlule. Ifekthri ayinayo ingcindezi yokusungula, futhi isimo sophenyo esisezansi nomfula ukuze sithuthuke, singene emakethe kanye nokuthengwa kwempahla okuphakathi nendawo, okuqhutshwa umoya wokuthenga, kulindeleke ukuthi imakethe isengakhuphuka kuleli sonto.
17, ngesonto eledlule, ukushaqeka kwemakethe ye-ethylene glycol yasekhaya kunamandla. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela emhlabeni wonke; Njengamanje, ukuqhubeka kwechweba ukuya echwebeni kumbalwa uma kuqhathaniswa; Nakuba amanye amayunithi e-ethylene glycol aqalwa kabusha, kwakusenamayunithi athile alungiswayo kanye nokwehliswa okungekuhle, futhi ukukhushulwa kokunikezwa kwakungaphansi kunokulindelekile. Isiphetho se-polyester esingezansi siqala ukugcina ukusebenza kwesidingo esiphezulu, esizinzile. Kulindeleke ukuthi ukuhlanganiswa kwesikhawu se-glycol ntambama kungenzeka kuqine.
18, ngesonto eledlule, imakethe yasekhaya ye-diethylene glycol yokushintshashintsha kokubuyela emuva. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela emhlabeni wonke; Okwamanje, umthwalo oqalayo wokufakwa kwasekhaya uhlala uphansi, ukugcwaliswa kwenani lokusuka kwelinye ichweba kulinganiselwe, futhi isimo sezulu esingesihle sithinta ukwehla okuqhubekayo kokufakwa kwempahla echwebeni, ngakho-ke imboni yezinhlaka ezingaphansi komfula ithanda ukuba buthaka. Ukuhlanganiswa kokushaqeka kwemakethe kulindeleke ukuthi kube khona kakhulu kuleli sonto.
19. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela emhlabeni jikelele; Ikusasa eliphakeme lithuthukisa indawo; Ukufakwa kwe-Petrochemical kwenyuka uma kuqhathaniswa nesikhathi sangaphambilini; Ukungqubuzana okuphezulu kwe-downstream, udinga nje ukuthenga; Izinga lokusebenza kwamabhizinisi asekhaya liphezulu, ingcindezi yokuhlinzeka isekhona. Ukufingqa, kulindeleke ukuthi leli sonto libe nokwenzeka lokuhlanganisa ukuntengantenga kwemakethe ye-PE yasekhaya.
20. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela emhlabeni jikelele; Ikusasa rose; Izinga le-Petrochemical destocking lehlile; Isidingo esiphansi somfula sizofika, sidinga nje ukuthatha izimpahla; Ukulahlekelwa kweyunithi yokulungisa kuyashintsha kancane. Ukufingqa, kulindeleke ukuthi imakethe ye-PP kuleli sonto inciphise amathuba okuhlanganiswa.
