Ngo-2022, izintengo zenqwaba yamakhemikhali zizoshintshashintsha kakhulu, zibonise amagagasi amabili entengo ekhuphukayo kusukela ngoMashi kuya kuJuni futhi kusukela ngo-Agasti kuya ku-Okthoba ngokulandelanayo. Ukwenyuka nokwehla kwamanani kawoyela kanye nokukhula kwesidingo ezinkathini eziyishumi eziphezulu zesiliva eziyisishiyagalolunye eziyishumi kuzoba yi-eksisi eyinhloko yokuguquguquka kwentengo yamakhemikhali ngo-2022.
Ngaphansi kwesizinda sempi yaseRussia Ukraine engxenyeni yokuqala ka-2022, uwoyela ongahluziwe wamazwe ngamazwe ugijima ngezinga eliphezulu kakhulu, izinga lentengo eliphelele lenqwaba yamakhemikhali liyaqhubeka nokukhuphuka, futhi imikhiqizo eminingi yamakhemikhali ifike phezulu eminyakeni yamuva nje. Ngokusho kwe-Jinlianchuang Chemical Index, kusukela ngoJanuwari kuya kuDisemba 2022, inkomba yemboni yamakhemikhali ihlotshaniswa kahle nenkambiso ye-WTI yamazwe ngamazwe kawoyela ongahluziwe, ene-coefficient yokuxhumanisa engu-0.86; Kusukela ngoJanuwari kuya kuJuni 2022, i-coefficient yokuhlobanisa phakathi kwakho kokubili iphezulu njenge-0.91. Lokhu kungenxa yokuthi umqondo wokukhuphuka kwemakethe yamakhemikhali yasekhaya engxenyeni yokuqala yonyaka ilawulwa ngokuphelele ukwanda kukawoyela ongahluziwe wamazwe ngamazwe. Kodwa-ke, njengoba ubhubhane lunqande ukufunwa nokusetshenziswa kwezinto, umsebenzi wakhungatheka ngemuva kokukhuphuka kwentengo. NgoJuni, ngenani eliphezulu likawoyela ongahluziwe, intengo yenqwaba yamakhemikhali yehle kakhulu, futhi amaphuzu avelele emakethe engxenyeni yokuqala yonyaka afika ekupheleni.
Engxenyeni yesibili ka-2022, ingqondo ehamba phambili yemakethe yemboni yamakhemikhali izosuka ezintweni ezingavuthiwe (uwoyela ongahluziwe) iye kweziyisisekelo. Kusukela ngo-Agasti kuya ku-Okthoba, kuncike esidingweni sesizini ephakeme yegolide eyisishiyagalolunye yesiliva, imboni yamakhemikhali inokwenyuka okuphawulekayo futhi. Kodwa-ke, ukungqubuzana phakathi kwezindleko eziphakeme zomfula kanye nesidingo esibuthakathaka somfula akuthuthukisiwe kakhulu, futhi intengo yemakethe inomkhawulo uma iqhathaniswa nengxenye yokuqala yonyaka, bese yehla ngokushesha ngemva kokukhanyisa epanini. NgoNovemba Disemba, kwakungekho mkhuba wokuqondisa ukushintshashintsha okubanzi kukawoyela ongahluziwe wamazwe ngamazwe, futhi imakethe yamakhemikhali yaphela ibuthakathaka ngaphansi kokuqondiswa kwesidingo esibuthakathaka.
Ishadi Lethrendi le-Jinlianchuang Chemical Index 2016-2022

Ngo-2022, izimakethe ze-aromatics nezansi nomfula zizoqina phezulu futhi zibe buthaka emfuleni ongezansi
Ngokwentengo, i-toluene nexylene kuseduze nokuphela kwempahla eluhlaza (uwoyela ongahluziwe). Ngakolunye uhlangothi, uwoyela ongahluziwe ukhuphuke kakhulu, kanti ngakolunye uhlangothi, uqhutshwa ukukhula kokuthunyelwa kwamanye amazwe. Ngo-2022, ukukhuphuka kwentengo kuzoba okugqame kakhulu ochungechungeni lwezimboni, kokubili okungaphezulu kwama-30%. Kodwa-ke, i-BPA ne-MIBK ku-chain chain phenol ketone izolula kancane kancane ku-2022 ngenxa yokuntuleka kokuhlinzekwa ngo-2021, futhi umkhuba wentengo jikelele wezintambo ze-phenol ketone ezikhuphukayo nezingezansi azilona ithemba, ngokwehla okukhulu konyaka nonyaka okungaphezu kuka-30% ku-2022; Ikakhulukazi, i-MIBK, enokwenyuka okuphezulu kwentengo kumakhemikhali ngo-2021, izocishe ilahlekelwe isabelo sayo ngo-2022. I-benzene ehlanzekile namaketango angezansi ngeke kushise ngo-2022. Njengoba ukunikezwa kwe-aniline kuqhubeka nokuqina, isimo esizumayo seyunithi kanye nokwenyuka okuqhubekayo kokuthunyelwa ngaphandle, ukukhuphuka kwentengo ehlobene ye-aniline yezinto ezingavuthiwe kungafana nalokho kwe-benzene eluhlaza. Emkhankasweni wokwenyuka okukhulu ekukhiqizweni kwesinye i-downstream styrene, i-cyclohexanone ne-adipic acid, ukukhuphuka kwentengo kumaphakathi, ikakhulukazi i-caprolactam iyona kuphela ku-benzene ehlanzekile kanye neketango eliphansi lomfula lapho intengo yehla unyaka nonyaka.

Mayelana nenzuzo, i-toluene, i-xylene ne-PX eduze nokuphela kwempahla eluhlaza kuzoba nokukhuphuka okukhulu kwenzuzo ngo-2022, konke okuzoba ngaphezu kwama-yuan angu-500/ton. Kodwa-ke, i-BPA kuchungechunge lwe-phenol ketone engezansi izoba nokwehla kwenzuzo enkulu kunazo zonke ku-2022, ngaphezu kwe-8000 yuan / ton, eqhutshwa ukwanda kokunikezwa kwayo kanye nesidingo esibi kanye nokwehla kwe-phenol ketone ephezulu. Phakathi kwamaketango ahlanzekile e-benzene kanye naphansi komfula, i-aniline izophelelwa izindleko ngo-2022 ngenxa yobunzima bokuthola umkhiqizo owodwa, ngokukhula okukhulu konyaka nonyaka kwenzuzo. Eminye imikhiqizo, kuhlanganise ne-benzene ehlanzekile, yonke izoba nenzuzo ephansi ngo-2022; Phakathi kwazo, ngenxa yomthamo omningi, ukunikezwa kwemakethe kwe-caprolactam kwanele, isidingo esingezansi somfula sibuthakathaka, ukwehla kwezimakethe kukhulu, ukulahlekelwa kwebhizinisi kuyaqhubeka kudlondlobala, futhi ukwehla kwenzuzo kukhulu kakhulu, cishe ku-1500 yuan/ton.

Mayelana nomthamo, ngo-2022, imboni enkulu yokucwenga kanye namakhemikhali ingene ekugcineni kokunwetshwa kwamandla, kodwa ukunwetshwa kwe-PX kanye nemikhiqizo etholakalayo efana ne-benzene emsulwa, i-phenol ne-ketone kusasebenza ngokugcwele. Ngo-2022, ngaphandle kokuhoxiswa kwamathani angu-40000 e-aniline ku-hydrocarbon enephunga elimnandi kanye neketango eliphansi lomfula, yonke eminye imikhiqizo izokhula. Lesi futhi isizathu esikhulu esenza ukuthi intengo emaphakathi yonyaka yemikhiqizo emnandi neyokwehla komfula ngo-2022 ingakahambi kahle unyaka nonyaka, yize inkambiso yentengo yama-aromatics nemikhiqizo eyehlayo iqhutshwa ukwanda kukawoyela ongahluziwe engxenyeni yokuqala yonyaka.
