Kwi-2023, kunye nomthamo osemthethweni we-Anhui Zhonghuifa New Materials Co., LTD. Imveliso yonyaka ye-120,000 yeetoni zezixhobo ze-butanone, umthamo wemveliso we-butanone waseTshayina uyaqhubeka nokukhula. Ekupheleni kwe-2023, umthamo wonyaka wemveliso yeshishini lasekhaya le-butyl ketone yi-915,000 yeetoni, ukwanda kwe-15.09%. Nangona kunjalo, ngenxa yokuvalwa kwexesha elide kwezinye izixhobo, amandla okuvelisa asebenzayo e-butyl ketone yasekhaya yi-670,000 yeetoni kuphela ngonyaka. Ngokwezibalo zeLongzhong Information, imveliso yasekhaya ye-butanone kwi-2023 iphelele kwiitoni ezingama-482,600, ukuhla kwe-4.60%. Ngelo xesha, imveliso inqabile, ngokukodwa ngenxa yenzuzo enganeleyo yesixhobo, imfuno ebuthakathaka kunye nezinye izinto.

Njengoko kunokubonwa kumfanekiso ongentla, emva kokubetha inqanaba eliphantsi kwikota yesibini, imveliso yebutanone yaqala ukunyuka kwikota yesithathu kwaye yafikelela kwinqanaba eliphezulu lonyaka kwikota yesine. Oku kwakubangelwa ngokukodwa ukuba ezinye iiyunithi zokucoca zalungiswa kwikota yesibini, kwaye ngenxa yexabiso eliphantsi le-butanone, izityalo zomntu ngamnye ezineendleko eziphezulu zokuvelisa ziqhutywe kwimithwalo encitshisiweyo, okubangele ukuhla okukhulu kwimveliso ngexesha lomjikelo. Phakathi kwabo, isixhobo seenwele zegolide seNingbo sangena kwixesha lokugcinwa ngo-Matshi 11, kwaye saphinda saqalisa imveliso eqhelekileyo ekupheleni kuka-Epreli. Indawo yokucoca kunye neekhemikhali iHarbin yangena kwixesha lokugcinwa kwayo ekupheleni kuka-Epreli kwaye yaphinda yaqalisa imveliso ekupheleni kukaJuni. Izixhobo ze-Qixiang Tengda Huangdao zingene kwixesha lokulondoloza ekuqaleni kukaMeyi, kwaye zibuyele kwisiqhelo ekuqaleni kukaJulayi; Iplanti yepetrochemical yaseLanzhou yangena kwixesha lokugcinwa kwe-10 kaJuni, kwaye yabuyela kwimeko yesiqhelo phakathi ku-Agasti. Kwikota yesithathu, izityalo zepetrochemical ze-Xinjiang Tianli kunye ne-Fushun zayeka ekuqaleni kukaJulayi. I-Anhui Zhonghui Fa imveliso yonyaka yeetoni ze-120,000 zezixhobo ezitsha nazo zikhutshwe ngokusemthethweni ekuqaleni kukaJulayi, ukuveliswa kwe-butyl ketone kwanda kakhulu xa kuthelekiswa nekota yesibini. Kwikota yesine, isixhobo somthi we-Dongming Pear saqala kwakhona phakathi koNovemba kwaye sayeka ngenxa yesiphoso ngoDisemba 11. I-Hubei Ruiyuan Petrochemical yaqala ngasekupheleni kukaNovemba ukugcina ukusebenza komthwalo ophantsi, kunye nokuveliswa kwe-butyl ketone kwafikelela kwindawo ephezulu kwikota yesine. , iyonke i-165,900 yeetoni, inyuke ngama-27.91% ukusuka kwikota yesithathu.

Ngokwezibalo zeLongzhong Information, imveliso yasekhaya ye-butanone kwi-2023 iphelele kwiitoni ezingama-482,600, ukuhla kwe-4.60%. Ngelo xesha, imveliso inqabile, ngokukodwa ngenxa yenzuzo enganeleyo yesixhobo, imfuno ebuthakathaka kunye nezinye izinto. Ngo-2023, ngenxa yexabiso eliphezulu lekhabhoni yesine emva kwe-ether ekrwada, umda wenzuzo wesityalo se-butyl ketone ucinezele kakhulu. Ukuthatha umzi-mveliso waseShandong njengomzekelo, ngo-2023, ixabiso eliqhelekileyo lonyaka kumzi-mveliso eShandong emva kwe-ether carbon four market yi-5250 yuan/ton, ixabiso eliqhelekileyo lonyaka lomzi-mveliso kwi-butyl ketone yi-7547 yuan/toni, kwaye ngonyaka. ixabiso lenzuzo malunga 500 yuan / ton, phantsi nge 70%. Enye inxalenye yeendleko eziphezulu zomzi-mveliso wexesha elide ilahleko karhulumente, kwimeko enjalo, inzondelelo yokuvelisa umenzi akwanelanga ngokunzulu, ukuvalwa, ukuncipha okungekuhle kunye nokwanda kweziganeko, izinga lokusetyenziswa komthamo jikelele liphantsi kakhulu, kodwa likwabangelwa imveliso ye-butanone ayizange inyuke ngamandla okuvelisa kunye nesizathu esikhulu sokukhula ngokukhawuleza.
