Intshayelelo: Kwikota yesithathu ka-2023, ngemveliso egudileyo yeseti yesine yeetoni ezingama-600 amawaka zesityalo se-ethylbenzene dehydrogenation eZhejiang Petrochemical kunye neetoni ezingama-200 amawaka zesityalo se-ethylbenzene dehydrogenation eNingxia Baofeng, umthamo wemveliso ye-styrene yasekhaya ufikelele kwi-21.292 yezigidi zeetoni, imveliso yezi seti zimbini zezixhobo, kodwa ikwabonisa ukuba izixhobo ezintsha zalo nyaka zisondela ekupheleni konyaka, okanye ziitoni ezingama-120 amawaka kuphela zezixhobo ezintsha eLuoyang Petrochemical ezinokuqaliswa ukusebenza.

Umthamo wemveliso ye-styrene yasekhaya ka-2023 ukugcina ukukhula okukhawulezileyo, ukususela ekuqaleni komthamo omtsha wemveliso weetoni ezi-3.7 yezigidi ngonyaka, ukwanda kweetoni ezingama-860,000 kunyaka ophelileyo, njengoko umthamo wemveliso iyonke yoshishino lwangoku unyuke waya kwi-21.292 yezigidi zeetoni, ukukhula komthamo we-21.03%, ukukhula komthamo ukugcina umkhwa wokukhula ophezulu. Ukongeza, ukuchithwa kwe-ethylbenzene yayiyeyona nkqubo iphambili yesityalo esitsha esaqaliswa ukusebenza kulo nyaka, ibiza i-83.78%.

Sijonge phambili ku-2024, ngokwendlela eqondwa ngayo imakethi ngoku, iiyunithi ze-styrene ezingakhange zifakwe kwimveliso ziiyunithi ze-Luoyang Petrochemical kunye ne-CITIC Guoan styrene, izixhobo ezisakhiwayo ziiyunithi ze-Jingbo Petrochemical (Zhongtai Chemical) kunye ne-Shenghong refining kunye ne-chemical styrene, kwaye ezinye izixhobo zeshishini zikwinqanaba lokuvunywa nokulinda ukwakhiwa, ngokusekelwe kumjikelo wokwakha. Amathuba amakhulu okuqalisa ukusebenza ngo-2024 anciphile kakhulu xa kuthelekiswa no-2023, kwaye izinga lokukhula kwamandla emveliso liyehla.
