Introduction: I ke kolu o ka hapaha o 2023, me ka hana maalea o ka ha o ka 600 tausani tona o ka ethylbenzene dehydrogenation mea kanu ma Zhejiang Petrochemical a me 200 tausani tona o ka ethylbenzene dehydrogenation mea kanu ma Ningxia Baofeng, ka huina o ka hale styrene hana hiki i 21.292 miliona. , ka hana ʻana o kēia mau pūʻulu ʻelua, akā hōʻike pū ʻia hoʻi e kokoke ana nā mea hana hou o kēia makahiki i ka hopena o ka makahiki, a i ʻole he 120 tausani mau toni o nā mea hana hou ma Luoyang Petrochemical hiki ke hoʻokomo ʻia.

2023 ʻO ka hiki i ka home styrene hana ke hoʻomau i ka ulu wikiwiki, 2023 mai ka hoʻomaka ʻana o ka mana hana hou 3.7 miliona tons / makahiki, kahi hoʻonui o 860,000 tons ma luna o ka makahiki i hala, e like me ka nui o ka nui o ka hana o kēia manawa i hoʻonui ʻia i 21.292 miliona tons , ka hoʻonuiʻana i ka mana o 21.03%, ka uluʻana o ka hiki ke mālama i ka ulu ulu kiʻekiʻe. Eia kekahi, ʻo ka ethylbenzene dehydrogenation ke kaʻina hana nui o ka mea kanu hou i hoʻokomo ʻia i loko o ka makahiki, helu no 83.78%.

Ke nānā nei i ka makahiki 2024, e like me ka ʻike mākeke o kēia manawa, ʻo nā ʻāpana styrene i hoʻokomo ʻole ʻia i loko o ka hana ʻo Luoyang Petrochemical a me CITIC Guoan styrene units, ʻo nā mea hana i kūkulu ʻia ʻo Jingbo Petrochemical (Zhongtai Chemical) a me Shenghong hoʻomaʻemaʻe a me nā ʻāpana styrene kemika, a ʻo ke koena o nā ʻoihana ʻoihana ka hapa nui i ka ʻae ʻia a ke kali ʻia nei ke kahua kūkulu, e pili ana i ke kaʻina hana. ʻO ka nui nui o ka hoʻokomo ʻana i ka hana ma 2024 ua hoʻemi nui ʻia i ka hoʻohālikelike ʻia me 2023, a ke lohi nei ka ulu ʻana o ka hiki ke hana.
