I ke kakahiaka o Dekemaba 27, 2020, ua hoʻolaha ʻia nā makana ʻoihana Kina 6, nā makana hoʻomaikaʻi a me nā makana koho. Ua lanakila ka papahana ʻenehana hou o ka hana ʻōmaʻomaʻo caprolactam hou a Baling Petrochemical i ka makana ʻenehana Kina a ʻo ia wale nō ka ʻāpana lanakila o Sinopec. Me ke kākoʻo o ke Kuhina ʻEpekema a me ka ʻenehana a me ka Natural Science Foundation o Kina, ua hoʻololi ka Baling Petrochemical and Petrochemical Research Institute i nā hopena noiʻi ʻepekema i loaʻa ma ka noiʻi kumu i nā ʻenehana hou. Ma hope o 30 mau makahiki, ua lanakila nā hanauna ʻekolu i nā pilikia a me nā pilikia he nui, ua hoʻomohala i kahi hoʻonohonoho piha o nā ʻenehana ʻōmaʻomaʻo me nā kuleana waiwai noʻonoʻo kūʻokoʻa, ua uhaki maikaʻi i ka monopoly haole ma ka ʻenehana hana caprolactam no 70 mau makahiki, a ua hoʻokumu i ke kiʻi hōʻailona o ka ʻenehana hana hou kūʻokoʻa o Kina. I kēia manawa, ua piʻi ka nui o ka lawa ponoʻī o ka caprolactam kūloko mai 30% a 94%, a ua emi nui ka hilinaʻi o koʻu ʻāina i ka ʻenehana haole a me nā huahana i lawe ʻia mai.

1.30 mau makahiki o ka hana hou kūʻokoʻa, ua hoʻomohala pono i kahi hoʻonohonoho piha o nā ʻenehana hou no ka hana ʻōmaʻomaʻo o ka caprolactam

He mea maka kemika organik koʻikoʻi ʻo Caprolactam. Ma ke ʻano he monomer no ka hana ʻana i nā olonā synthetic nylon-6 a me nā plastics ʻenekinia nylon-6, hoʻohana nui ʻia ia i nā lole, nā kaʻa, nā mea uila a me nā ʻoihana ʻē aʻe e hoʻohana ana i nā mea hou no ka hana hou. Pili loa ka ʻoihana caprolactam i ka ikaika waiwai o ka ʻāina a me nā kūlana ola o ka poʻe, a noho i kahi kūlana koʻikoʻi i ka hoʻomohala ʻana a me ka hoʻomaikaʻi mau ʻana i ka hoʻokele waiwai o ka ʻāina.

I ka hoʻomaka ʻana o nā makahiki 1990, ua hoʻolilo ʻo Sinopec i kahi kokoke i 10 biliona yuan e hoʻolauna i 3 mau seti o 50,000 tons/makahiki nā hale hana hana caprolactam, i kūkulu ʻia ma Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. a me Shijiazhuang Refinery. Ma hope mai, ua lawe ka hui Sinopec i ka ʻenehana koʻikoʻi o ka hana caprolactam-ka hoʻomākaukau ʻana o ka cyclohexanone oxime ma ke ʻano he holomua, a ua hoʻokō i kahi hoʻonohonoho piha o nā ʻenehana hou no ka hana caprolactam ʻōmaʻomaʻo ma Baling Petrochemical. Me ke kākoʻo ikaika o ke Kuhina o ka ʻEpekema a me ka ʻenehana a me ka National Natural Science Foundation o Kina, a me ke alakaʻi ʻana a Academician Min Enze lāua ʻo Academician Shu Xingtian o ka Chinese Academy of Sciences, ua hana pū ka hui noiʻi me ka ʻoiaʻiʻo a me ka hana ikaika. I nā makahiki 30 i hala iho nei, ua hoʻokumu ʻia ma mua o 100 mau palapala hoʻopaʻa inoa kūloko a me nā ʻāina ʻē. Ua hoʻomohala ʻia kahi hoʻonohonoho piha o nā ʻenehana hou no ka hana ʻōmaʻomaʻo o ka caprolactam i hoʻohui ʻia e nā ala hana hou, nā mea catalytic hou a me ka ʻenekinia hana hou.

ʻEono mau ʻenehana koʻikoʻi o kēia hoʻonohonoho piha o nā ʻenehana hou, a ua hōʻea lākou a pau i ka pae alakaʻi honua. ʻO lākou ka ʻenehana hana slurry bed cyclohexanone ammoximation hoʻokahi-reactor e hana i ka cyclohexanone oxime, ka ʻenehana hoʻonohonoho hou ʻekolu-paepae cyclohexanone oxime Beckman, ka ʻenehana crystallization neutralization Ammonium sulfate, ka ʻenehana hydrorefining caprolactam hydrorefining i hoʻopaʻa ʻia me ka magnetic, ka hoʻonohonoho hou ʻana o ka pae kinoea cyclohexanone oxime e hana i ka ʻenehana caprolactam, ka hydrogenation esterification cyclohexene e hana i ka ʻenehana hou cyclohexanone. I waena o lākou, ua hoʻohana ʻia nā ʻenehana 4 mua ma ka ʻoihana, a ua hoʻokumu ʻia he 137 mau palapala hoʻopaʻa no ka hana kūloko a me nā ʻāina ʻē; ua lanakila ʻia he 17 mau makana panalāʻau a me nā kuhina, me 1 makana mua no ka hana ʻenehana aupuni a me 1 makana lua no ka holomua ʻepekema a me ka ʻenehana aupuni.

ʻO ke kaʻina hana hoʻonohonoho hou ʻana o ke kinoea cyclohexanone oxime a Baling Petrochemical me ka ʻole o ka ammonium sulfate by-product" ua holomua nui hoʻi i ka hoʻomākaukau ʻana i ka catalyst, ka ʻenehana hana, ka hoʻomaʻemaʻe huahana, a me nā mea ʻē aʻe, a ua hoʻopau i ka noiʻi ʻenehana liʻiliʻi a me ka hoʻāʻo. 50,000 tons/makahiki noi ʻoihana. Eia kekahi, ua hoʻomaka ʻo Sinopec i ka "Cyclohexene Esterification Hydrogenation i Cyclohexanone New Process". ʻO ka nui o ka hoʻohana ʻana i ka atom carbon ua kokoke i ka 100%, ʻaʻole wale ka hoʻohana ʻana i ka ikehu haʻahaʻa, akā hiki ke hana pū i ka ethanol absolute. Ua pau ka noiʻi hoʻāʻo. E hoʻokō koke ʻia ka hoʻomohala ʻana i ka pūʻolo hana 200,000 tons/makahiki, a me ka noi ʻoihana 200,000 tons/makahiki.

2. Hoʻokele ka ʻenehana hou i ka hoʻomohala ikaika o nā ʻoihana hou, ka neʻe ʻana a me ka hoʻonui ʻana e pale i kahi muliwai wai maʻemaʻe

I kēia lā, ua lilo ʻo Baling Petrochemical i ʻoihana nui i hui pū ʻia me ka petrochemical a me ke kemika lanahu, a me ka ʻoihana hana caprolactam a me ka lithium rubber nui loa a me kahi kahua hana resin epoxy koʻikoʻi. I waena o lākou, ʻo ke kaulahao huahana caprolactam e komo pū ana me 500,000 tons/makahiki caprolactam (me nā hui like 200,000 tons), 450,000 tons/makahiki cyclohexanone, a me 800,000 tons/makahiki ammonium sulfate. Ua hoʻokō nā ʻenehana hou i ka holomua ʻenehana i nā ʻoihana kuʻuna i nā ʻoihana kuʻuna. ʻAʻole wale ia he ʻoi aku ka launa pū me ke kaiapuni, ua hoʻemi ʻia ka hoʻokuʻu ʻana o ka haumia i kēlā me kēia huahana ma 50%, a ua hoʻemi ʻia ke kumukūʻai hana ʻāpana ma 50%, a ua hoʻemi ʻia ka hoʻopukapuka kālā i ka hiki ke hana no 10,000 tons i lalo o 150 miliona yuan. ʻO ka hōʻemi ʻana o kahi kokoke i 80% ua hoʻopuka i nā pono waiwai a me nā pono kaiāulu koʻikoʻi.

Ua hoʻolaha nui ka ʻenehana hou o ka hana ʻana o ka caprolactam ʻōmaʻomaʻo i ka hoʻomohala wikiwiki ʻana o ka caprolactam a me kāna mau ʻoihana ma hope. I ka hopena o 2019, ua kūkulu ʻo Sinopec i nā hale hana hana caprolactam he nui ma Baling Petrochemical, Zhejiang Baling Hengyi a me nā ʻoihana ʻē aʻe, me ka nui o ka hana ʻana he 900,000 tons/makahiki, e helu ana i 12.16% o ka hiki ke hana caprolactam honua a me ka hiki ke hana caprolactam kūloko o 24.39%. I kēia manawa, ua hiki aku ka hiki ke hana caprolactam ʻōmaʻomaʻo o koʻu ʻāina i 4 miliona tons, e lilo ana i mea hana nui loa o ka honua, me ka māhele mākeke honua ma mua o 50%, e hoʻokumu ana i kahi ʻoihana e kū mai ana he 40 biliona yuan, a ke hoʻokele nei i ka hoʻomohala ikaika ʻana o 400 biliona mau ʻoihana ma hope.

I ka makahiki 2020, e hoʻomaka ʻia ka papahana hoʻoneʻe a me ka hoʻonui ʻana i ke kaulahao ʻoihana caprolactam a Baling Petrochemical me ka huina kālā he 13.95 biliona yuan ma Hunan Yueyang Green Chemical Industrial Park. Hoʻohana ka papahana i kahi pūʻulu o nā ʻenehana hou i hoʻomohala kūʻokoʻa ʻia e Sinopec e kūkulu i kahi kaulahao ʻoihana caprolactam 600,000-ton/makahiki. E kūkulu ʻia ka papahana ma ke ʻano he papahana hōʻike a me kahi papahana hoʻohālikelike no ka "mālama ʻana i kahi muliwai a me ka wai maʻemaʻe", e uhaki ana i ka "hoʻopuni kemika o ka muliwai", a me ka hoʻokō ʻana i ka neʻe ʻana o nā ʻoihana hana kemika weliweli ma nā wahi kūlanakauhale i noho nui ʻia ma ka ʻāina.
