Ngokwedatha yokuthumela ngaphandle ngo-2022, yasekhayabutanoneumthamo wokuthunyelwa kwempahla kumazwe angaphandle ukususela ngoJanuwari ukuya ku-Oktobha uphelele kwiitoni ezingama-225600, ukwanda ngama-92.44% kwangelo xesha linye kulo nyaka uphelileyo, kwafikelela kwelona nqanaba liphezulu kwangelo xesha linye phantse kwiminyaka emithandathu. Kuphela ngoFebruwari ukuthunyelwa kwempahla kumazwe angaphandle bekungaphantsi kunonyaka ophelileyo, ngelixa uJanuwari, uMatshi, u-Epreli, uMeyi noJuni beziphezulu kunexesha elifanayo kulo nyaka uphelileyo. Isizathu sokunyuka okubukhali kokuthunyelwa kwempahla kumazwe angaphandle xa kuthelekiswa nonyaka ophelileyo kukuba ubhubhani wamazwe ngamazwe uya kuqhubeka nokuvubela ngo-2021, ngakumbi eMzantsi-mpuma Asia nakweminye imimandla, kwaye umthwalo wokusebenza kwezityalo zebutanone ezisezantsi ziphantsi, nto leyo enciphisa imfuno yebutanone. Ukongeza, iiyunithi zebutanone zangaphandle zisebenza ngokuqhelekileyo ngaphandle kokugcinwa kweyunithi, kwaye unikezelo lwangaphandle luzinzile, ngoko ke umthamo wokuthunyelwa kwe-butanone wonyaka ophelileyo wawucolile. Kwisiqingatha sokuqala salo nyaka, echatshazelwa kukuqhambuka kwemfazwe yaseRussia yaseUkraine, iYurophu yayinqongophele ukubonelela ngenxa yemozulu eshushu, eyakhokelela ekunyukeni okubukhali kwamaxabiso kwaye yandisa umahluko wexabiso kunye neemarike zasekhaya. Bekukho indawo ethile ye-arbitrage ukunyusa umdla wamashishini asekhaya okuthengisa kumazwe angaphandle; Ukongeza, kuchatshazelwa kukuvalwa kwezityalo ezimbini zebutanone zeMarusan Petrochemical kunye neDongran Chemical, ukubonelela phesheya kolwandle kuyaqina kwaye imfuno iguqukela kwintengiso yaseTshayina.
Ngokwexabiso lokuthelekisa ixabiso, i-avareji yexabiso lenyanga le-butanone yokuthumela ngaphandle ukusuka ngoJanuwari ukuya ku-Oktobha ka-2022 yayingaphezulu kwe-1539.86 yeedola zase-US / itoni, ukunyuka kwe-444.16 yeedola zase-US / itoni xa kuthelekiswa nexesha elifanayo kulo nyaka uphelileyo, kwaye ibonise ukunyuka okuphezulu.
Ngokwembono yamaqabane orhwebo lokuthumela ngaphandle, i-butanone yase-China ethumela ngaphandle ukusuka kuJanuwari ukuya ku-Okthobha ngowama-2022 iza kuya ikakhulu eMpuma Asia, kuMzantsi-mpuma Asia, iYurophu, iMelika nakwamanye amazwe, kwaye ipateni yokuthumela ngaphandle iyafana naleyo kwiminyaka edlulileyo. Amazwe amathathu aphezulu yi-South Korea, iVietnam kunye ne-Indonesia, i-akhawunti ye-30%, i-15% kunye ne-15% ngokulandelanayo. Ukuthunyelwa kumazwe angaphandle kuMzantsi-mpuma Asia kubalelwa kwi-37% iyonke. Kwiminyaka yakutshanje, ngokwandiswa kokuthunyelwa kwempahla kuMbindi noMzantsi Asia, eYurophu naseUnited States, ukuthunyelwa kwebutanone kumazwe angaphandle kuyaqhubeka nokuphumela, yaye isikali sokuthumela ngaphandle sisaqhubeka sisanda.

Ngokweenkcukacha-manani zendawo yokubhaliswa kwempahla kumazwe angaphandle, iPhondo laseShandong liza kuba nowona mthamo mkhulu wokuthumela ngaphandle kwebutanone ngo-2022, nomthamo wokuthumela ngaphandle ukuya kutsho kwiitoni eziyi-158519.9, ezibalelwa kuma-70%. Ummandla une-Qixiang Tengda 260000 t/a butanone plant enesona sixhobo sikhulu sokuvelisa ibutanone e-China kunye neShandong Dongming Lishu 40000 t/a butanone plant, phakathi kwayo iShandong Qixiang iyindawo enkulu yasekhaya ye-butanone. Eyesibini liPhondo laseGuangdong, elinomthamo othunyelwa ngaphandle we-28618 yeetoni, ezibalelwa kwi-13%.
