Hoʻolauna: I ka hapaha ʻekolu o 2023, me ka hana maʻalahi o ka set ʻehā o 600 tausani tons o ka hale hana ethylbenzene dehydrogenation ma Zhejiang Petrochemical a me 200 tausani tons o ka hale hana ethylbenzene dehydrogenation ma Ningxia Baofeng, ua hōʻea ka huina o ka hana styrene kūloko i 21.292 miliona tons, ʻo ka hana ʻana o kēia mau set ʻelua o nā mea hana, akā hōʻike pū kekahi ua kokoke mai nā lako hou o kēia makahiki i ka hopena o ka makahiki, a i ʻole 120 tausani tons wale nō o nā lako hou ma Luoyang Petrochemical e hoʻokomo ʻia i ka hana.

2023 Ka hiki ke hana styrene kūloko e mālama i ka ulu wikiwiki, 2023 mai ka hoʻomaka ʻana o ka hiki ke hana hou he 3.7 miliona tons/makahiki, he piʻi ʻana o 860,000 tons ma luna o ka makahiki i hala, e like me ka nui o ka hiki ke hana o ka ʻoihana o kēia manawa i piʻi i 21.292 miliona tons, ka ulu ʻana o ka hiki o 21.03%, ka ulu ʻana o ka hiki ke mālama i kahi ʻano ulu kiʻekiʻe. Eia kekahi, ʻo ka ethylbenzene dehydrogenation ke kaʻina hana nui o ka hale hana hou i hoʻokomo ʻia i loko o ka makahiki, e helu ana i 83.78%.

Ke nānā nei i mua i ka makahiki 2024, e like me ka ʻike o ka mākeke o kēia manawa, ʻo nā ʻāpana styrene i hoʻokomo ʻole ʻia i ka hana ʻana, ʻo ia nā ʻāpana Luoyang Petrochemical a me CITIC Guoan styrene, ʻo nā mea hana e kūkulu ʻia nei ʻo Jingbo Petrochemical (Zhongtai Chemical) a me Shenghong refining a me chemical styrene units, a ʻo ke koena o nā mea hana ʻoihana e ʻae ʻia ana a ke kūkulu ʻia nei, ma muli o ke kaʻina hana kūkulu. Ua emi nui ka hiki ke hoʻokomo i ka hana i ka makahiki 2024 i hoʻohālikelike ʻia me 2023, a ke lohi nei ka ulu ʻana o ka hiki ke hana.
