Ngo-2023, ngomthamo osemthethweni we-Anhui Zhonghuifa New Materials Co., LTD. wonyaka wokukhiqiza amathani ayi-120,000 emishini ye-butanone, amandla okukhiqiza i-butanone eShayina ayaqhubeka nokukhula. Ekupheleni kuka-2023, amandla okukhiqiza minyaka yonke embonini ye-butyl ketone yasekhaya angamathani ayi-915,000, ukwanda okungu-15.09%. Kodwa-ke, ngenxa yokuvalwa kwesikhathi eside kwamanye amadivayisi, amandla okukhiqiza asebenzayo e-butyl ketone yasekhaya angamathani ayi-670,000 kuphela ngonyaka. Ngokwezibalo ze-Longzhong Information, ukukhiqizwa kwe-butanone yasekhaya ngo-2023 kwafinyelela amathani angama-482,600, ukwehla okungu-4.60%. Ngesikhathi esifanayo, ukukhiqizwa kwehle, ikakhulukazi ngenxa yokuntuleka kwenzuzo kwedivayisi, isidingo esibuthakathaka nezinye izici.

Njengoba kungabonakala esithombeni esingenhla, ngemva kokufinyelela iphuzu eliphansi kwikota yesibili, ukukhiqizwa kwe-butanone kwaqala ukukhuphuka kwikota yesithathu futhi kwafinyelela ezingeni eliphakeme kakhulu lonyaka kwikota yesine. Lokhu kwakubangelwa kakhulu ukuthi amanye amayunithi okucwenga alungiswa kwikota yesibili, futhi ngenxa yentengo ephansi ye-butanone, izitshalo ngazinye ezinezindleko zokukhiqiza eziphakeme zagijima ngemithwalo encishisiwe, okwaholela ekwehleni okukhulu kokukhiqiza phakathi nomjikelezo. Phakathi kwazo, idivayisi yezinwele zegolide yaseNingbo yangena esikhathini sokulungisa ngoMashi 11, futhi yaqala kabusha ukukhiqiza okuvamile ekupheleni kuka-Ephreli. Isitshalo sokuhlanza namakhemikhali saseHarbin sangena esikhathini sokulungisa ekupheleni kuka-Ephreli futhi saqala kabusha ukukhiqiza ngasekupheleni kukaJuni. Imishini yaseQixiang Tengda Huangdao yangena esikhathini sokulungisa ekuqaleni kukaMeyi, yabuyela esimweni esijwayelekile ekuqaleni kukaJulayi; Isitshalo se-petrochemical saseLanzhou sangena esikhathini sokulungisa ngoJuni 10, sabuyela esimweni esijwayelekile maphakathi no-Agasti. Kwikota yesithathu, izitshalo ze-petrochemical zaseXinjiang Tianli naseFushun zayeka ekuqaleni kukaJulayi. Umkhiqizo waminyaka yonke we-Anhui Zhonghui Fa wamathani ayi-120,000 emishini emisha nawo okhishwe ngokusemthethweni ekuqaleni kukaJulayi, ukukhiqizwa kwe-butyl ketone kukhuphuke kakhulu uma kuqhathaniswa nekota yesibili. Kwikota yesine, idivayisi yesihlahla se-Dongming Pear yaqala kabusha maphakathi noNovemba futhi yema ngenxa yephutha ngoDisemba 11. I-Hubei Ruiyuan Petrochemical yaqala ngasekupheleni kukaNovemba ukuze iqhubeke nokusebenza komthwalo ophansi, kanti ukukhiqizwa kwe-butyl ketone kwafinyelela ezingeni eliphezulu kwikota yesine, okulinganiselwa kumathani ayi-165,900, okwenyuke ngo-27.91% kusuka kwikota yesithathu.

Ngokwezibalo zeLongzhong Information, ukukhiqizwa kwe-butanone yasekhaya ngo-2023 kwafinyelela ku-482,600 amathani, ukwehla ngo-4.60%. Ngesikhathi esifanayo, ukukhiqizwa kwehlile, ikakhulukazi ngenxa yokuntuleka kwenzuzo eyanele yedivayisi, isidingo esibuthakathaka nezinye izici. Ngo-2023, ngenxa yentengo ephezulu ye-carbon four ngemva kwe-ether yezinto zokusetshenziswa, inzuzo yesitshalo se-butyl ketone icindezelwa kakhulu. Uma sithatha ifektri yaseShandong njengesibonelo, ngo-2023, intengo ejwayelekile yonyaka yefektri eShandong ngemva kwemakethe ye-ether carbon four ingu-5250 yuan/ton, intengo ejwayelekile yonyaka yefektri ku-butyl ketone ingu-7547 yuan/ton, kanti inzuzo yonyaka ingu-500 yuan/ton, yehle ngo-70%. Enye ingxenye yezindleko eziphakeme zesimo sokulahlekelwa isikhathi eside kwefektri, esimweni esinjalo, intshiseko yokukhiqiza yomkhiqizi ayanele kakhulu, ukuvalwa, ukwehla okungekuhle kanye nezinye izimo kuyanda, izinga lokusetshenziswa kwamandla lilonke lehle kakhulu, kodwa futhi okubangelwa ukukhiqizwa kwe-butanone akuzange kukhuphuke kanye namandla okukhiqiza kanye nesizathu esiyinhloko sokukhula okusheshayo.
