Ngemva kokuba i-benzene/hydrobenzene emsulwa yehle yaya kuma-yuan angu-6000, iqhutshwa ukulula kwenqubomgomo kazwelonke, umuzwa we-bullish wemakethe washintsha kancane, abanye abadayisi kanye nokuthengwa kwentengo ephansi, ivolumu yokuthengiselana ye-benzene/hydrobenzene emsulwa, bakhuthaze ukwenyuka kwentengo, kusukela ngoJuni 16, intengo kawoyela we-benzene eShandong yayicishe ibe ngu-6220 yuan/ton, ukwanda okungu-80-140 yuan/ton. Kwabeka isisekelo sokubuya kwe-hydrobenzene kuleli sonto.

Njengamanje, ukugxila kwemakethe kukwenyuka kwezinga lokusetshenziswa kwamandla e-styrene, ukwehla kwezinga lokusebenza kwe-phenol kanye nokwanda kokungeniswa kwe-benzene emsulwa.

1, ukusetshenziswa kwamandla e-styrene okuyinhloko okuphansi kulindeleke ukuthi kwande

Ingxenye yokuqala yesitshalo se-styrene esimisiwe ihlela ukuqala kabusha, kanye ne-Zhejiang Petrochemical, amathani angu-600,000 emishini abekwe ngo-15:00 ngoJuni 16, kusukela kudatha yokukhiqizwa kwe-styrene yaseShayina kanye nokusetshenziswa kwamandla kulindeleke ukuthi kuthuthukise konke. Ukusetshenziswa kwamandla e-styrene kuzokhulisa isidingo se-benzene emsulwa, kuzokhulisa ukusetshenziswa kwe-benzene emsulwa, kodwa ngemva kokwanda kwesilinganiso sokusebenza kwe-styrene, kusadingeka ukunaka ukufaniswa kwe-styrene engezansi, uma ukwehla kwe-styrene kunzima ukufeza ukuthuthuka okuhambisanayo, i-styrene ibhekene nesimo sokuncipha kokuhlinzekwa kanye nesidingo, phela, i-styrene izongena kancane kancane ekushiseni okuphezulu ngaphandle kwesizini.

2, izinga lokusebenza kwe-phenol ketone liyaqhubeka nokwehla

Muva nje amabhizinisi e-phenol ketone aqale ezingeni lika-69%, inyanga nenyanga -1%. Phakathi kwawo, ngesikhathi sokuvalwa nokugcinwa kwamayunithi e-phenol ketone e-Jiangsu Ruiheng, eShanghai Sisar naseGaoqiao Petrochemical, amayunithi e-phenol ketone okuhlanza e-Shenghong abe nokusebenza okungekuhle, ngakho izinga lokusebenza kwe-phenol ketone laqhubeka nokwehla, kunciphisa ukusetshenziswa kwe-benzene emsulwa, futhi kwakha impendulo engemihle ku-benzene/hydrobenzene emsulwa.

3, ukungeniswa kwe-benzene emsulwa eShayina kulindeleke ukuthi kwande

Njengoba isikhathi sokuhlushwa kokugcinwa kwamanye amazwe sesiphelile, kanye nomqondo we-octane value usuphelile, i-benzene emsulwa yase-Asia idinga ukungena eShayina ukuze igaywe, futhi kulindeleke ukuthi ukungeniswa kwe-benzene emsulwa yasekhaya kuzokwanda, okuholela ekukhuleni kokutholakala kwe-benzene emsulwa yasekhaya, kusukela ekubukeni kokungeniswa kwanyanga zonke, ukungeniswa kwamanye amazwe noma kusukela kumathani angu-200,000 kuya ku-300,000 esikalini.

Ngaphezu kwalokho, i-Hainan Refining kanye ne-Chemical entsha engamathani ayizigidi ezingu-2.6 okuphakelayo okuguqulayo, i-CNOOC Huizhou entsha engamathani ayizigidi ezingu-1.3 okuphakelayo okuguqulayo kwama-aromatics kanye nokungalingani kulindeleke ukuthi kufakwe ekudleni kamuva, ukunikezwa kwe-benzene emsulwa yasekhaya kwanda.

Esikhathini esifushane, okubandakanya ukugcwaliswa kabusha okukodwa okungenalutho ekupheleni kwenyanga, kulindeleke ukuthi isimo sokuthenga se-benzene/hydrobenzene emsulwa singathuthukiswa, futhi intengo ye-hydrobenzene ingase izinze futhi ibuye, kodwa ukuphakama namandla okubuyela emuva kunqunyelwe, ngoba imakethe isesezindabeni ezimbi, futhi umugqa ophakathi node uphathwa ngemibono engenalutho.
