Ngowama-2023, ngomthamo osemthethweni wemveliso yonyaka ye-Anhui Zhonghuifa New Materials Co., LTD. yeetoni ezili-120,000 zezixhobo ze-butanone, amandla okuvelisa i-butanone eTshayina ayaqhubeka nokukhula. Ekupheleni kuka-2023, amandla okuvelisa ngonyaka kwishishini le-butyl ketone lasekhaya 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 ngonyaka. Ngokwezibalo zeLongzhong Information, imveliso yasekhaya ye-butanone ngo-2023 iyonke yayiziitoni ezingama-482,600, ukwehla kwe-4.60%. Kwangaxeshanye, imveliso iye yehla, ikakhulu ngenxa yokungabikho kwenzuzo eyaneleyo yesixhobo, imfuno ebuthathaka kunye nezinye izinto.

Njengoko kunokubonwa kumfanekiso ongentla, emva kokufikelela kwinqanaba eliphantsi kwikota yesibini, imveliso ye-butanone yaqala ukunyuka kwikota yesithathu yaza yafikelela kwinqanaba eliphezulu lonyaka kwikota yesine. Oku kwakubangelwa ikakhulu kukuba ezinye iiyunithi zokucoca zalungiswa kwikota yesibini, kwaye ngenxa yexabiso eliphantsi le-butanone, izityalo nganye ezineendleko eziphezulu zemveliso zazisebenza ngemithwalo ephantsi, nto leyo eyabangela ukwehla okukhulu kwemveliso ngexesha lomjikelo. Phakathi kwazo, isixhobo seenwele zegolide saseNingbo sangena kwixesha lokulungisa ngoMatshi 11, saza saqalisa kwakhona imveliso eqhelekileyo ekupheleni kuka-Epreli. Isityalo sokucoca kunye neekhemikhali saseHarbin sangena kwixesha lokulungisa ekupheleni kuka-Epreli saza saqalisa kwakhona imveliso ngasekupheleni kukaJuni. Izixhobo zeQixiang Tengda Huangdao zangena kwixesha lokulungisa ekuqaleni kukaMeyi, zaza zabuyela kwisiqhelo ekuqaleni kukaJulayi; Isityalo se-petrochemical saseLanzhou sangena kwixesha lokulungisa ngoJuni 10, saza sabuyela kwisiqhelo phakathi ku-Agasti. Kwikota yesithathu, izityalo ze-petrochemical zaseXinjiang Tianli naseFushun zayeka ekuqaleni kukaJulayi. Imveliso yonyaka ye-Anhui Zhonghui Fa yeetoni ezili-120,000 zezixhobo ezintsha nayo ikhutshwe ngokusesikweni ekuqaleni kukaJulayi, imveliso ye-butyl ketone inyuke kakhulu xa ithelekiswa nekota yesibini. Kwikota yesine, isixhobo somthi we-Dongming Pear saqala kwakhona phakathi kuNovemba saza sayeka ngenxa yempazamo ngoDisemba 11. I-Hubei Ruiyuan Petrochemical yaqala ekupheleni kukaNovemba ukugcina ukusebenza komthwalo omncinci, kwaye imveliso ye-butyl ketone yafikelela kwinqanaba eliphezulu kwikota yesine, iyonke ifikelela kwiitoni ezili-165,900, inyuke ngama-27.91% ukusuka kwikota yesithathu.

Ngokwezibalo zeLongzhong Information, imveliso yasekhaya ye-butanone ngo-2023 yayifikelela kwiitoni ezingama-482,600, ukwehla kwe-4.60%. Kwangaxeshanye, imveliso yehlile, ikakhulu ngenxa yokungabikho komvuzo oneleyo wesixhobo, imfuno ebuthathaka kunye nezinye izinto. Ngo-2023, ngenxa yexabiso eliphezulu le-carbon four emva kwe-ether yezinto eziluhlaza, umvuzo wenzuzo wesityalo se-butyl ketone uncitshiswe kakhulu. Ukuthatha umzekelo wefektri yaseShandong, ngo-2023, ixabiso eliqhelekileyo lonyaka lomzi-mveliso eShandong emva kwemarike ye-ether carbon four yi-5250 yuan/ton, ixabiso eliqhelekileyo lonyaka lomzi-mveliso kwi-butyl ketone yi-7547 yuan/ton, kwaye ixabiso lenzuzo lonyaka limalunga ne-500 yuan/ton, lihle nge-70%. Enye inxalenye yeendleko eziphezulu zemeko yokulahlekelwa kwexesha elide kumzi-mveliso, kwimeko enjalo, umdla womenzi kwimveliso awonelanga kakhulu, ukuvalwa, ukuncipha okungalunganga kunye nezinye izinto ziyanda, izinga lokusetyenziswa kwamandla lilonke liphantsi kakhulu, kodwa likwabangelwa yimveliso ye-butanone engazange inyuke kunye namandla emveliso kunye nesizathu esiphambili sokukhula ngokukhawuleza.
