Isingeniso: Engxenyeni yesithathu ka-2023, ngokukhiqizwa okubushelelezi kwesethi yesine yamathani ayizinkulungwane ezingu-600 e-ethylbenzene dehydrogenation plant e-Zhejiang Petrochemical kanye namathani ayizinkulungwane ezingu-200 e-ethylbenzene dehydrogenation plant e-Ningxia Baofeng, isamba sokukhiqiza i-styrene yasekhaya safinyelela amathani ayizigidi ezingu-21.292. , ukukhiqizwa kwalawa masethi amabili emishini, kodwa futhi kubonisa ukuthi imishini emisha yalo nyaka isondela ekupheleni konyaka, noma amathani ayizinkulungwane ezingu-120 kuphela emishini emisha eLuoyang Petrochemical angase asetshenziswe.

2023 Umthamo wokukhiqiza wasekhaya we-styrene ukuze ulondoloze ukukhula okusheshayo, ngo-2023 kusukela ekuqaleni kwamandla amasha okukhiqiza amathani ayizigidi ezingu-3.7 / ngonyaka, ukwanda kwamathani angu-860,000 ngonyaka odlule, njengoba umthamo wokukhiqiza wemboni yamanje ukhuphuke waba amathani ayizigidi ezingu-21.292 , ukukhula kwamandla okungama-21.03%, ukukhula kwamandla ukuze kugcinwe umkhuba wokukhula okuphezulu. Ukwengeza, i-ethylbenzene dehydrogenation bekuyinqubo esemqoka yefekthri entsha eqale ukusebenza phakathi nonyaka, ebalelwa ku-83.78%.

Sibheke phambili ku-2024, ngokokuqonda kwamanje kwemakethe, amayunithi e-styrene angakafakwa ekukhiqizweni amayunithi e-Luoyang Petrochemical kanye ne-CITIC Guoan styrene, amadivaysi asakhiwayo yi-Jingbo Petrochemical (Zhongtai Chemical) kanye ne-Shenghong refining kanye ne-chemical styrene units, futhi amanye amathuluzi ebhizinisi ngokuvamile asesigabeni sokugunyazwa nesalindile sokwakha, ngokusekelwe emjikelezweni wokwakha. Amathuba amakhulu okuqalisa ukusebenza ngo-2024 ancipha kakhulu uma kuqhathaniswa no-2023, futhi izinga lokukhula kwamandla okukhiqiza liyancipha.
