Imbonakalo yeMarike yeZixhobo zeKhemikhali

Imbonakalo yeMethanol

Imarike ye-methanol yasekhaya kulindeleke ukuba ibone utshintsho olwahlukileyo kwixesha elifutshane. Kwizibuko, ukunikezelwa kwempahla ngaphakathi elizweni kunokuqhubeka nokuphuma kwi-arbitrage, kwaye ngokufika okuxineneyo kwiveki ezayo, umngcipheko wokuqokelelwa kwezinto ezikhoyo usekhona. Phakathi kolindelo lokunyuka kokungeniswa kwezinto kwamanye amazwe, ukuzithemba kwemarike yexesha elifutshane kubuthathaka. Nangona kunjalo, ukunqunyanyiswa kwe-Iran kwentsebenziswano ne-UN nuclear watchdog kunika inkxaso ethile kwezoqoqosho. Amaxabiso e-port methanol anokuguquguquka phakathi kwezinto ezixubeneyo ze-bullish kunye ne-bearish. Abavelisi be-methanol abangaphakathi, abaphezulu baneempahla ezikhoyo, kwaye ukugcinwa okuxineneyo kwakutshanje kwizityalo zemveliso kugcina uxinzelelo lokubonelela luphantsi. Nangona kunjalo, uninzi lwamacandelo asezantsi—ngakumbi i-MTO—ajongene nelahleko enkulu kunye nokukwazi ukudlula iindleko okuncinci. Ukongeza, abasebenzisi abasezantsi kwiindawo zokusetyenziswa baneempahla eziphezulu zezinto eziluhlaza. Emva kokunyuka kwamaxabiso kule veki, abarhwebi balumkile malunga nokusukela ezinye iinzuzo, kwaye ngaphandle komsantsa wokubonelela kwimarike, amaxabiso e-methanol angaphakathi kwilizwe kulindeleke ukuba ahlangane phakathi kweemvakalelo ezahlukeneyo. Ingqwalasela esondeleyo kufuneka inikwe kwi-port inventory, ukuthengwa kwe-olefin, kunye nophuhliso lwezoqoqosho.

Imbonakalo yeFormaldehyde

Amaxabiso e-formaldehyde asekhaya kulindeleke ukuba ahlangane ngokukhetha okubuthathaka kule veki. Uhlengahlengiso lokubonelela lunokwenzeka ukuba lunciphe, ngelixa imfuno evela kumacandelo asezantsi afana neepaneli zomthi, imihombiso yasekhaya, kunye nezibulali-zinambuzane incipha ngokwexesha lonyaka, iqiniswa zizinto zemozulu. Ukuthengwa kuya kuhlala kusekelwe kwiimfuno. Njengoko amaxabiso e-methanol kulindeleke ukuba atshintshe ngokwahlukileyo kunye nokuncipha kokuguquguquka, inkxaso ecaleni kweendleko ze-formaldehyde iya kuncitshiswa. Abathathi-nxaxheba kwimarike kufuneka bajonge ngokusondeleyo amanqanaba ezinto ezikhoyo kwizityalo zepaneli zomthi ezisezantsi kunye neendlela zokuthengwa kulo lonke uthotho lokubonelela.

Imbonakalo ye-Acetic Acid

Imarike ye-acetic acid yasekhaya kulindeleke ukuba ihlale ibuthathaka kule veki. Ubonelelo kulindeleke ukuba lunyuke, njengoko iyunithi yaseTianjin isenokuqalisa ukusebenza kwaye isityalo esitsha saseShanghai Huayi sinokuqala ukuvelisa kwiveki ezayo. Kulindeleke ukuba kubekho ukuvalwa okucwangcisiweyo kolondolozo, okugcina amazinga okusebenza ephezulu kunye nokugcina uxinzelelo olukhulu lokuthengisa. Abathengi abasezantsi baya kugxila ekuqondeni iikhontrakthi zexesha elide kwisiqingatha sokuqala senyanga, kunye nemfuno ebuthathaka. Abathengisi kulindeleke ukuba bahlale bezimisele kakhulu ukukhupha izinto ezisetyenzisiweyo, mhlawumbi ngamaxabiso ancitshisiweyo. Ukongeza, amaxabiso e-methanol feedstock anokwehla kwiveki ezayo, nto leyo ebeka uxinzelelo kwimarike ye-acetic acid.

Imbonakalo ye-DMF

Imarike ye-DMF yasekhaya kulindeleke ukuba ihlangane ngolindelo lokubona kule veki, nangona abavelisi basenokuthi bazame ukuxhasa amaxabiso, kunye nokunyuka okuncinci okunokwenzeka. Kwicala lokubonelela, isityalo saseXinghua sivaliwe, ngelixa iyunithi yeSigaba II saseLuxi kulindeleke ukuba iqhubeke nokunyuka, ishiya ukubonelela ngokubanzi kuzinzile. Imfuno ihlala inciphile, kunye nabathengi abasezantsi begcina ukuthengwa okusekelwe kwiimfuno. Amaxabiso e-Methanol feedstock anokubona utshintsho olwahlukileyo, kunye ne-port methanol etshintsha phakathi kwezinto ezahlukeneyo kunye namaxabiso angaphakathi ehlangana. Imvakalelo yemarike ilumkile, kunye nabathathi-nxaxheba abaninzi belandela iindlela zemarike kwaye begcina ukuzithemba okuncinci kwimbono yexesha elifutshane.

Imbonakalo yePropylene

Utshintsho lwamva nje kwimfuno yobonelelo luphazanyiswa lutshintsho oluqhubekayo kwiiyunithi ezisezantsi neziphezulu, ingakumbi iinkampani eziqalayo eziqinileyo kunye nokuvalwa kweeyunithi zePDH kule nyanga, kunye nokulungiswa okucwangcisiweyo kwezinye izityalo ezinkulu ezisezantsi. Nangona inkxaso kwicala lobonelelo ikhona, ubuthathaka bemfuno buthintela ukunyuka kwamaxabiso, nto leyo egcina iimvakalelo zemarike zilumkile. Amaxabiso epropylene kulindeleke ukuba athambekele kancinci kule veki, kujongwe kakhulu imisebenzi yeeyunithi zePDH kunye notshintsho olukhulu kwizityalo ezisezantsi.

Imbonakalo yeGranule yePP

Uxinzelelo kwicala lobonelelo luyanda njengoko umlinganiselo wemveliso osemgangathweni uhla, kodwa amandla amatsha—iZhenhai Refining Phase IV eMpuma China kunye nomgca wesine weYulong Petrochemical eMntla China—aqalile ukunyuka, onyusa kakhulu unikezelo lwemarike kwaye acinezela amaxabiso e-homo- kunye ne-copolymer zasekuhlaleni. Zimbalwa izinto ezicwangcisiweyo zokuvala ulondolozo kule veki, nto leyo enciphisa ngakumbi ilahleko yonikezelo. Amacandelo asezantsi afana neengxowa ezilukiweyo kunye neefilimu asebenza ngamanani aphantsi, ikakhulu esebenzisa izinto ezikhoyo, ngelixa imfuno yokuthumela ngaphandle iyancipha. Imfuno ebuthathaka iyonke iyaqhubeka nokuthintela imakethi, ngokungabikho kwezinto ezintle ezibangela ukuba umsebenzi worhwebo unciphe. Uninzi lwabathathi-nxaxheba lunembono engalunganga, belindele ukuba amaxabiso e-PP anciphe ekudibaneni.
