Emva kokuba i-benzene/hydrobenzene ecocekileyo yehle yaya kuma-6000 yuan, iqhutywa kukukhululeka okuhle komgaqo-nkqubo welizwe, imvakalelo yokunyuka kwemarike yatshintsha kancinci, abanye abathengisi kunye nokuthengwa kwexabiso eliphantsi, umthamo wentengiselwano ye-benzene/hydrobenzene ecocekileyo, bakhuthaze ukunyuka kwamaxabiso, ukusukela nge-16 kaJuni, ixabiso le-benzene yeoyile yaseShandong lalimalunga ne-6220 yuan/ton, ukunyuka kwe-80-140 yuan/ton. Wabeka isiseko sokubuya kwe-hydrobenzene kule veki.

Okwangoku, ingqwalasela yemarike ikukwanda kwesantya sokusetyenziswa kwamandla e-styrene, ukwehla kwesantya sokusebenza kwe-phenol kunye nokwanda kokungeniswa kwe-benzene ecocekileyo.

1, ukusetyenziswa kwamandla e-styrene asezantsi kulindeleke ukuba kwande

Inxalenye yokuqala yesityalo se-styrene esimisiweyo iceba ukuqala kwakhona, kunye neZhejiang Petrochemical, iitoni ezingama-600,000 zezixhobo zibekwe ngentsimbi ye-15 nge-16 kaJuni, ukusuka kwidatha yemveliso ye-styrene kunye nokusetyenziswa kwamandla eTshayina kulindeleke ukuba iphucule iyonke. Ukusetyenziswa kwamandla e-styrene kuya kwandisa imfuno ye-benzene ecocekileyo, kuya kwandisa ukusetyenziswa kwe-benzene ecocekileyo, kodwa emva kokwanda kwezinga lokusebenza kwe-styrene, kusafuneka kuthathelwe ingqalelo ukuhambelana kwe-styrene esezantsi, ukuba ukwehla kwe-styrene kunzima ukufikelela kuphuculo oluhambelanayo, i-styrene ijongene nemeko yokubonelela kunye nokunciphisa imfuno, emva kwayo yonke loo nto, i-styrene iya kungena kancinci kancinci kubushushu obuphezulu ngaphandle kwexesha lonyaka.

2, izinga lokusebenza kwe-phenol ketone esezantsi liyaqhubeka nokuhla

Kutshanje amashishini e-phenol ketone aqale kwinqanaba le-69%, inyanga nenyanga -1%. Phakathi kwawo, ngexesha lokuvalwa nokugcinwa kweeyunithi ze-phenol ketone zeJiangsu Ruiheng, iShanghai Sisar kunye neGaoqiao Petrochemical phenol ketone, iiyunithi ze-phenol ketone zokucokisa iShenghong zazine-negative operation, ngoko ke izinga lokusebenza kwe-phenol ketone laqhubeka nokwehla, kunciphisa ukusetyenziswa kwe-benzene ecocekileyo, kwaye kwakha impendulo engalunganga kwi-benzene ecocekileyo/hydrobenzene.

3, kulindeleke ukuba ukungeniswa kwe-benzene ecocekileyo eTshayina kunyuke

Njengoko ixesha lokugcinwa kwamanye amazwe liphelile, kwaye ingqiqo yexabiso le-octane iphelile, i-benzene ecocekileyo yase-Asia kufuneka ingene eTshayina ukuze ityiwe, kwaye kulindeleke ukuba ukungeniswa kwe-benzene ecocekileyo yasekhaya kuya kwanda, nto leyo ekhokelela ekunyukeni kokunikezelwa kwe-benzene ecocekileyo yasekhaya, ngokwembono yokungeniswa kwenyanga, ukungeniswa kwempahla kwamanye amazwe okanye ukusuka kwiitoni ezingama-200,000 ukuya kwiitoni ezingama-300,000 zesikali.

Ukongeza, iHainan Refining kunye neChemical ezintsha ezizizigidi ezi-2.6 zeetoni zokutya okuhlaziyayo, iCNOOC Huizhou entsha ezizizigidi ezili-1.3 zeetoni zokuhlaziya imveliso ye-aromatics kunye ne-disproportionation kulindeleke ukuba zifakwe ekutyeni kamva, unikezelo lwasekhaya lwe-benzene ecocekileyo lwanda.

Kwixesha elifutshane, elibandakanya ukuphinda kuzaliswe i-single engenanto ekupheleni kwenyanga, kulindeleke ukuba imeko-bume yokuthenga i-benzene/hydrobenzene ecocekileyo iphuculwe, kwaye ixabiso le-hydrobenzene lingazinza kwaye liphinde libuyele, kodwa ukuphakama kunye namandla okubuyela kuncitshisiwe, kuba imakethi isekwindaba ezimbi, kwaye umgca ophakathi node uphathwa ngeengcamango ezingenanto.
