Ngokusho kwedatha yokuthekelisa ngo-2022, okwasekhayabutanoneUmthamo wokuthekelisa kusukela kuMasingana kuya kuMfumfu uhlanganise amathani angu-225600, okuwukukhuphuka ngo-92.44% esikhathini esifanayo ngonyaka odlule, okufinyelele izinga eliphezulu kakhulu esikhathini esifanayo cishe eminyakeni eyisithupha. Ukuthunyelwa kwamanye amazwe kwangoFebhuwari kuphela kube ngaphansi kunonyaka odlule, kuyilapho uMasingana, Mashi, Ephreli, Meyi noJuni bekuphezulu kunesikhathi esifanayo ngonyaka odlule. Isizathu sokwenyuka okukhulu kwezimpahla ezithunyelwa ngaphandle uma kuqhathaniswa nonyaka odlule ukuthi ubhubhane lwamazwe ngamazwe luzoqhubeka nokuvunda ngo-2021, ikakhulukazi eNingizimu-mpumalanga ye-Asia nakwezinye izifunda, futhi umthwalo wokusebenza wezitshalo ze-butanone ezingezansi uphansi, okhawulela isidingo se-butanone. Ukwengeza, amayunithi e-butanone angaphandle asebenza ngokujwayelekile ngaphandle kokunakekelwa kweyunithi, futhi ukunikezwa kwamanye amazwe kuzinzile uma kuqhathaniswa, ngakho ivolumu yokuthekelisa ye-butanone yangonyaka odlule ibintekenteke. Engxenyeni yokuqala yalo nyaka, ethintekile ukuqubuka kwempi yaseRussia yase-Ukraine, iYurophu yayishoda ngenxa yesimo sezulu esishisayo, okwaholela ekwenyukeni okukhulu kwamanani futhi kwandise umehluko wamanani nemakethe yasekhaya. Kwakukhona indawo ethile ye-arbitrage yokwandisa isasasa lamabhizinisi asekhaya ukuze athunyelwe ngaphandle; Ngaphezu kwalokho, okuthintwe ukuvalwa kwezitshalo ezimbili ze-butanone ze-Marusan Petrochemical kanye ne-Dongran Chemical, ukunikezwa phesheya kwezilwandle kuyaqina futhi isidingo siphendukela emakethe yaseChina.
Mayelana nokuqhathaniswa kwentengo, isilinganiso senani lenyanga lentengo lokuthunyelwa kwe-butanone kusukela ngoJanuwari kuya ku-Okthoba 2022 lalingaphezu kwamadola ase-US angu-1539.86/ton, okuwukunyuka kwamadola angama-444.16 aseMelika/ithani uma kuqhathaniswa nesikhathi esifanayo ngonyaka odlule, futhi kwabonisa ukukhuphuka okuphelele.
Ngokombono wozakwethu bohwebo lokuthumela ngaphandle, ukuthunyelwa kwe-butanone yaseChina kusukela ngoJanuwari kuya ku-Okthoba ngo-2022 kuzoya ikakhulukazi e-East Asia, Southeast Asia, Europe, America nakwamanye amazwe, futhi iphethini yokuthekelisa ngokuyisisekelo iyafana neyaseminyakeni edlule. Amazwe amathathu ahamba phambili yiSouth Korea, Vietnam kanye ne-Indonesia, abalelwa ku-30%, 15% no-15% ngokulandelana. Izimpahla ezithunyelwa ngaphandle eziya eNingizimu-mpumalanga ye-Asia zibalelwa ku-37% sezizonke. Eminyakeni yamuva nje, ngokwanda kokuthunyelwa kwempahla kwamanye amazwe e-Asia Ephakathi naseNingizimu, eYurophu nase-United States, ukuthunyelwa kwe-butanone kuyaqhubeka nokugqashuka, futhi izinga lokuthumela ngaphandle liyaqhubeka nokukhula.

Ngokwezibalo zendawo yokubhalisela ukuthunyelwa kwamanye amazwe, iSifundazwe saseShandong sizoba nomthamo omkhulu kakhulu wokuthekelisa we-butanone ngo-2022, nevolumu yokuthekelisa ifinyelela kumathani ayi-158519.9, ebalelwa ku-70%. Lesi sifunda sinesitshalo se-Qixiang Tengda 260000 t/a butanone esinamandla amakhulu okukhiqiza i-butanone e-China kanye ne-Shandong Dongming Lishu 40000 t/a butanone plant, lapho i-Shandong Qixiang ingumkhiqizi omkhulu wasekhaya we-butanone. Okwesibili yiSifundazwe sase-Guangdong, esinomthamo wokuthekelisa wamathani angama-28618, okubalelwa ku-13%.
