Isingeniso: Kwikota yesithathu ka-2023, ngokukhiqizwa okubushelelezi kwesethi yesine yamathani ayizinkulungwane ezingama-600 esitshalo sokukhipha i-ethylbenzene eZhejiang Petrochemical kanye namathani ayizinkulungwane ezingama-200 esitshalo sokukhipha i-ethylbenzene eNingxia Baofeng, umthamo wokukhiqiza we-styrene wasekhaya ufinyelele kumathani ayizigidi ezingama-21.292, ukukhiqizwa kwalawa masethi amabili amadivayisi, kodwa futhi kukhombisa ukuthi imishini emisha yalo nyaka isondela ekupheleni konyaka, noma amathani ayizinkulungwane eziyi-120 kuphela emishini emisha eLuoyang Petrochemical angase aqaliswe ukusebenza.

Umthamo wokukhiqiza we-styrene yasekhaya ka-2023 ukugcina ukukhula okusheshayo, kusukela ekuqaleni komthamo omusha wokukhiqiza wamathani ayizigidi ezingu-3.7 ngonyaka, ukwanda kwamathani angu-860,000 kulo lonke unyaka odlule, njengoba umthamo wokukhiqiza wamanje wamanje ukhuphuke wafika kumathani ayizigidi ezingu-21.292, ukukhula komthamo okungu-21.03%, ukukhula komthamo ukugcina umkhuba wokukhula ophezulu. Ngaphezu kwalokho, ukukhishwa kwe-ethylbenzene kwaba yinqubo eyinhloko yesitshalo esisha esaqala ukusebenza phakathi nonyaka, okubalwa ku-83.78%.

Uma sibheke phambili ku-2024, ngokusho kokuqonda kwamanje kwemakethe, amayunithi e-styrene angakafakwa ekukhiqizweni amayunithi e-Luoyang Petrochemical kanye ne-CITIC Guoan styrene, amadivayisi akhiwayo yi-Jingbo Petrochemical (Zhongtai Chemical) kanye namayunithi e-Shenghong refining kanye ne-chemical styrene, kanti amanye amadivayisi ebhizinisi asesigabeni sokwamukelwa kanye nokwakhiwa okulindile, ngokusekelwe emjikelezweni wokwakha. Amathuba amakhulu okusebenza ngo-2024 ancishiswe kakhulu uma kuqhathaniswa no-2023, futhi izinga lokukhula kwamandla okukhiqiza liyehla.
