Emva kokuba ibenzene/ihydrobenzene esulungekileyo yehle yaya kutsho kuma-6000 yuan mark, iqhutywa kukulula umgaqo-nkqubo wesizwe, isimo sengqondo sentengiso satshintsha kancinane, abanye abarhwebi kunye nokuthengwa kwempahla ephantsi, umthamo wetransekshini webenzene/hydrobenzene omsulwa, wakhuthaza ukunyuka kwexabiso NgoJuni 16, ixabiso le-oli ye-benzene ye-Shandong yayimalunga ne-6220 yuan/ton, ukunyuka kwe-80-140 yuan/ton. Sibeke isiseko se-hydrobenzene rebound yale veki.

Okwangoku, ugxininiso lwemarike kukunyuka kwesantya sokusetyenziswa komthamo we-styrene, ukuhla kwezinga lokusebenza kwe-phenol kunye nokunyuka kokungeniswa kwe-benzene ecocekileyo.

1, usetyenziso olumandla lwe-styrene esezantsi kulindeleke ukuba lunyuke

Inxalenye yokuqala yeplanti ye-styrene emisiweyo iceba ukuqalisa kwakhona, kunye ne-Zhejiang Petrochemical I-600,000 yeetoni zezixhobo zibekwe kwi-15 o 'clock ngoJuni 16, ukusuka kwimveliso ye-styrene yase-China kunye nokusetyenziswa kwedatha kulindeleke ukuba kuphuculwe ngokubanzi. Ukusetyenziswa komthamo we-styrene kuya kwandisa imfuno yebenzene ecocekileyo, kuya kwandisa ukusetyenziswa kwebenzene ecocekileyo, kodwa emva kokunyuka kwesantya sokusebenza kwe-styrene, kusafuneka ukuba ubeke ingqalelo ekufaniseni okusezantsi kwe-styrene, ukuba umlambo osezantsi we-styrene unzima ukuwenza. ukufezekisa ukuphuculwa kwe-synchronous, i-styrene ijongene nemeko yokubonelela kunye nokunciphisa imfuno, emva kwayo yonke loo nto, i-styrene iya kungena ngokuthe ngcembe kwiqondo lokushisa eliphezulu ngaphandle kwexesha.

I-2, izinga lokusebenza le-phenol ketone elisezantsi liqhubeka nokuhla

Ngoku kutshanje amashishini e-phenol ketone aqala kwinqanaba le-69%, inyanga-ngenyanga-1%. Phakathi kwabo, ngexesha lokuvalwa kunye nokugcinwa kwexesha le-Jiangsu Ruiheng, i-Shanghai Sisar kunye ne-Gaoqiao Petrochemical phenol ketone units, i-Shenghong yokucoca i-phenol ketone units yayinomsebenzi ongalunganga, ngoko ke izinga lokusebenza le-phenol ketone laqhubeka lihla, linciphisa ukusetyenziswa kwe-benzene ecocekileyo, kunye nokwenza. impendulo engalunganga kwi-benzene/hydrobenzene ecocekileyo.

I-3, ukuthengiswa kwe-benzene ecocekileyo yaseTshayina kulindeleke ukuba kunyuke

Ngokuphela kwexesha lokuxinana lokugcinwa phesheya kweelwandle, kunye nexabiso le-octane logic liwile, i-benzene ecocekileyo yase-Asia idinga ukungena e-China ukuze igaywe, kwaye kulindeleke ukuba ukuthengiswa kwe-benzene ecocekileyo yasekhaya kuya kwanda, okukhokelela ekunyukeni kwe-benzene ecocekileyo yasekhaya. ukubonelela, ukusuka kwindawo yokujonga ukungenisa elizweni, ukungenisa elizweni okanye ukusuka kwiitoni ezingama-200,000 ukuya kwi-300,000 yeetoni zesikali.

Ukongeza, i-Hainan Refining kunye neChemical entsha ye-2.6 yezigidi zeetoni zesondlo sokuguqula, i-CNOOC Huizhou entsha ye-1.3 yezigidi zeetoni zokuguqulwa kwemveliso ye-aromatics kunye nokungalingani kulindeleke ukuba ifakwe kwisondlo kamva, ukunikezelwa kwasekhaya kwe-benzene ecocekileyo kwanda.

Ngexesha elifutshane, elibandakanya ukuzaliswa okungenanto okukodwa ekupheleni kwenyanga, kulindeleke ukuba umoya wokuthenga webenzene/i-hydrobenzene ecocekileyo unokuphuculwa, kwaye ixabiso le-hydrobenzene linokuzinza kwaye libuyele, kodwa ukuphakama kunye namandla ilinganiselwe, kuba imarike isekho kwiindaba ezimbi, kwaye umgca ophakathi kunye nomde uphathwa ngeengcamango ezingenanto.
