Ngo-2022, amaxabiso amaninzi ekhemikhali aya kuguquguquka ngokubanzi, ebonisa amaza amabini okunyuka kwamaxabiso ukusuka ngoMatshi ukuya kuJuni kwaye ukususela ngo-Agasti ukuya ku-Oktobha ngokulandelelanayo. Ukunyuka kunye nokuhla kwamaxabiso eoyile kunye nokunyuka kwemfuno kwigolide yesilivere elithoba lamaxesha alishumi aphakamileyo kuya kuba yeyona nto iphambili yokuguquguquka kwexabiso lemichiza ngo-2022.
Ngaphantsi kwemvelaphi yemfazwe yaseRashiya yaseUkraine kwisiqingatha sokuqala sika-2022, i-oyile ekrwada yamazwe ngamazwe iqhuba kwinqanaba eliphezulu kakhulu, inqanaba lexabiso elipheleleyo leekhemikhali ezininzi liyaqhubeka nokunyuka, kwaye uninzi lweemveliso zeekhemikhali zibethe phezulu kwiminyaka yamuva. Ngokutsho kweJinlianchuang Chemical Index, ukususela ngoJanuwari ukuya kuDisemba 2022, intsingiselo yesalathisi soshishino lweekhemikhali ihambelana ngokufanelekileyo kunye ne-WTI yamazwe ngamazwe yeoli ekrwada, kunye ne-coefficient yokulungelelanisa ye-0.86; Ukususela ngoJanuwari ukuya kuJuni ka-2022, i-coefficient yokulungelelanisa phakathi kwezi zimbini iphezulu njenge-0.91. Oku kungenxa yokuba ingqiqo yokunyuka kwemarike yasekhaya yeekhemikhali kwisiqingatha sokuqala sonyaka ilawulwa ngokupheleleyo kukunyuka kwe-oli ekrwada kumazwe ngamazwe. Nangona kunjalo, njengoko ubhubhani uthintele imfuno kunye nolungiselelo, intengiselwano iye yaphazamiseka emva kokuba ixabiso linyuke. NgoJuni, ngexabiso eliphezulu le-oyile ekrwada yokuntywila, ixabiso lekhemikhali yesambuku sehle kakhulu, kwaye amanqaku entengiso kwisiqingatha sokuqala sonyaka afikelela esiphelweni.
Kwisiqingatha sesibini sika-2022, i-logic ekhokelayo kwimarike yoshishino lweekhemikhali iya kutshintsha ukusuka kwizinto eziluhlaza (i-oyile ekrwada) ukuya kwizinto ezisisiseko. Ukusukela ngo-Agasti ukuya ku-Okthobha, kuxhomekeke kwimfuno yegolide yesithoba yesilivere yeshumi yexesha eliphezulu, ishishini lemichiza linomgangatho obalulekileyo wokunyuka kwakhona. Nangona kunjalo, ukuchasana phakathi kweendleko eziphezulu zokunyuka kunye nemfuno ephantsi ye-downstream ayiphucukanga kakhulu, kwaye ixabiso lemarike lilinganiselwe xa lithelekiswa nesiqingatha sokuqala sonyaka, kwaye liyancipha ngokukhawuleza emva kwe-flash epanini. NgoNovemba kaDisemba, kwakungekho mkhwa wokukhokela ukuguquguquka okubanzi kwe-oyile ekrwada kumazwe ngamazwe, kwaye intengiso yeekhemikhali yaphela ibuthathaka phantsi kwesikhokelo semfuno ebuthathaka.
Itshathi yeTrendi ye-Jinlianchuang Chemical Index 2016-2022

Ngo-2022, i-aromatics kunye neemarike ezisezantsi ziya kuba namandla phezulu kwaye zibe buthathaka kumlambo osezantsi.
Ngokwexabiso, i-toluene kunye ne-xylene zisondele kwi-raw material (ioli ekrwada) ekupheleni. Kwelinye icala, i-oyile ekrwada inyuke kakhulu, kwaye kwelinye icala, iqhutywa kukukhula kokuthumela ngaphandle. Ngo-2022, ukunyuka kwexabiso kuya kuba yinto evelele kakhulu kwi-industrial chain, zombini ngaphezu kwe-30%. Nangona kunjalo, i-BPA kunye ne-MIBK kwi-phenol ketone chain chain iyancipha ngokuthe ngcembe kwi-2022 ngenxa yokunqongophala kokunikezelwa kwe-2021, kwaye ixabiso elipheleleyo leentambo ze-phenol ketone ezinyukayo kunye nezantsi azithembanga, kunye neyona nto inkulu yonyaka. ukwehla okungaphezulu kwama-30% ngowama-2022; Ngokukodwa, i-MIBK, enexabiso eliphezulu lokunyuka kweekhemikhali ngo-2021, iya phantse ilahlekelwe isabelo sayo ngo-2022. I-benzene ecocekileyo kunye ne-downstream chains ayiyi kuba shushu ngo-2022. iyunithi kunye nokunyuka okuqhubekayo kokuthunyelwa kwamanye amazwe, ukunyuka kwexabiso elihambelanayo le-aniline kunokuhambelana nento ekrwada ye-benzene ecocekileyo. Kwiphulo lokunyuka okukhulu kwimveliso yezinye i-styrene ezisezantsi, i-cyclohexanone kunye ne-adipic acid, ukunyuka kwexabiso kuphakathi, ngakumbi i-caprolactam kuphela kwe-benzene ecocekileyo kunye ne-downstream chain apho ixabiso lehla unyaka nonyaka.

Ngokubhekiselele kwinzuzo, i-toluene, i-xylene kunye ne-PX kufuphi nesiphelo sezinto eziluhlaza ziya kuba nenzuzo enkulu yokunyuka kwe-2022, yonke into eya kuba ngaphezu kwe-500 yuan / ton. Nangona kunjalo, i-BPA kwi-downstream phenol ketone chain iya kuba nenzuzo enkulu yokuhla kwi-2022, ngaphezu kwe-8000 yuan / ton, eqhutywe kukunyuka kokunikezelwa kwayo kunye nemfuno embi kunye nokwehla kwe-phenol ketone ephezulu. Phakathi kwamatyathanga e-benzene acocekileyo kunye ne-downstream, i-aniline iya kuphelelwa yindleko ngo-2022 ngenxa yobunzima bokufumana imveliso enye, kunye nokukhula okukhulu konyaka ngonyaka kwinzuzo. Ezinye iimveliso, kubandakanya imathiriyeli ecocekileyo yebenzene, zonke ziya kuba nengeniso ephantsi ngo-2022; Phakathi kwabo, ngenxa yobuninzi obuninzi, ukunikezelwa kweemarike ze-caprolactam kwanele, imfuno ephantsi yomlambo ibuthathaka, ukuhla kweemarike kukhulu, ilahleko yamashishini iyaqhubeka iqina, kwaye ukuhla kwenzuzo kukhulu, phantse i-yuan eyi-1500 / ton.

Ngokumalunga nomthamo, kwi-2022, i-industry-scale enkulu kunye ne-chemical industry ingene ekupheleni kokwandiswa kwamandla, kodwa ukwandiswa kwe-PX kunye neemveliso ezifana ne-benzene ecocekileyo, i-phenol kunye ne-ketone isahamba ngokupheleleyo. Ngo-2022, ngaphandle kokurhoxiswa kweetoni ezingama-40000 ze-aniline kwi-hydrocarbon enuka kamnandi kunye nekhonkco elisezantsi, zonke ezinye iimveliso ziya kukhula. Esi sesona sizathu siphambili sokuba kutheni ixabiso eliphakathi lonyaka leemveliso ezinuka kamnandi kunye neemveliso ezisezantsi ngo-2022 zingekabikho unyaka nonyaka, nangona ixabiso lezinto ezinuka kamnandi kunye neemveliso ezisezantsi ziqhutywa kukunyuka kweoyile ekrwada kwisiqingatha sokuqala sonyaka. .
