I te ata o te 27 o Tīhema, 2020, i panuitia te 6 o ngā Tohu Ahumahi Haina, ngā Tohu Whakamiharo me ngā Tohu Whakaingoa. I toa te kaupapa hangarau hou hou a Baling Petrochemical mō te hanga kākano matomato caprolactam i te Tohu Ahumahi Haina, ā, koinei anake te wāhanga toa o Sinopec. Nā te tautoko a te Manatū Pūtaiao me te Hangarau me te Natural Science Foundation o Haina, kua hurihia e te Baling Petrochemical and Petrochemical Research Institute ngā hua rangahau pūtaiao i whiwhihia i roto i te rangahau taketake hei hangarau hou. I muri i te 30 tau, e toru ngā whakatipuranga kua wikitoria i ngā hinganga me ngā raruraru maha, kua whakawhanake i tētahi huinga katoa o ngā hangarau matomato me ngā mana pupuri hinengaro motuhake, kua pakaru angitu te mana pupuri a tāwāhi ki te hangarau hanga kākano mō te 70 tau, ā, kua whakatūria te ahua waitohu o te hangarau auaha motuhake a Haina. I tēnei wā, kua piki ake te reiti whai rawa o te kākano ā-rohe mai i te 30% ki te 94%, ā, kua tino heke te whakawhirinaki o tōku whenua ki te hangarau tāwāhi me ngā hua kawemai.

1.30 tau o te auahatanga motuhake, i angitu te whakawhanake i tētahi huinga hangarau hou mō te hanga matomato o te caprolactam

He rauemi mata matū waro nui te Caprolactam. Hei monomer mō te hanga muka hangai nairona-6 me ngā kirihou hangarau nairona-6, e whakamahia whānuitia ana i roto i ngā kakahu, ngā motuka, ngā hikohiko me ētahi atu mara e whakamahi ana i ngā rauemi hou mō te auahatanga. He hononga tata te umanga caprolactam ki te kaha ōhanga o te whenua me ngā paerewa oranga o te tangata, ā, he tūranga nui tōna i roto i te whanaketanga me te whakapai tonu i te ōhanga o te motu.

I ngā tau tōmua o te tekau tau atu i 1990, tata ki te 10 piriona yuan te whakapaunga a Sinopec ki te whakauru i ngā huinga e 3 o ngā whare hanga caprolactam 50,000 tana/tau, i hangaia ki Baling Petrochemical, Nanjing DSM Dongfang Chemical Co., Ltd. me Shijiazhuang Refinery. I muri mai, i tangohia e te whakahaere Sinopec te hangarau matua o te hanga caprolactam - te whakarite i te cyclohexanone oxime hei putanga hou, ā, i whakahaerehia he huinga katoa o ngā hangarau hou mō te hanga caprolactam matomato ki Baling Petrochemical. Me te tautoko kaha a te Manatū Pūtaiao me te Hangarau me te National Natural Science Foundation o Haina, me te ārahi a te Kaiako Min Enze me te Kaiako Shu Xingtian o te Chinese Academy of Sciences, kua mahi tahi te rōpū rangahau me te kaha ki te mahi. I roto i ngā tau 30 kua pahure ake nei, neke atu i te 100 ngā patene hangahanga ā-rohe me tāwāhi kua hangaia. Kua whakawhanakehia he huinga katoa o ngā hangarau hou mō te hanga caprolactam matomato kua whakauruhia e ngā ara tauhohenga hou, ngā rauemi whakatere hou me te hangarau tauhohenga hou.

E ono ngā hangarau matua o tēnei huinga hangarau hou, ā, kua eke katoa ēnei ki te taumata rangatira o te ao. Ko ēnei ko te hangarau tukatuka whakapūmau cyclohexanone moenga paru kotahi-pūngao hei whakaputa cyclohexanone oxime, te hangarau whakaritenga-toru-wāhanga cyclohexanone oxime Beckman, te hangarau whakapūmau Ammonium sulfate, te hangarau whakapūmau aukume caprolactam moenga, te whakaritenga-hau hau cyclohexanone oxime hei whakaputa hangarau caprolactam, te whakapūmau cyclohexane esterification hydrogenation hei whakaputa hangarau hou cyclohexanone. I roto i ēnei, kua whakamahia ngā hangarau tuatahi e 4 ki te ahumahi, ā, kua whakatūria he 137 ngā patene hanga ā-rohe me tāwāhi; kua riro i a rātou he 17 ngā tohu ā-rohe me ngā tohu minita, tae atu ki te 1 te taonga tuatahi mō te hanga hangarau ā-motu me te 1 te taonga tuarua mō te ahunga whakamua pūtaiao me te hangarau ā-motu.

Kua angitu hoki te "tukanga whakarite moenga nekeneke cyclohexanone oxime hau-wāhanga me te kore he ammonium sulfate hua taha" a Baling Petrochemical i roto i te whakarite whakakorikori, te hangarau tauhohenga, te whakamahine hua, me ētahi atu, ā, kua oti te rangahau hangarau tauine iti me te tauine whakamātautau. 50,000 tāne/tau te tono ahumahi. Hei tāpiri, i tīmata a Sinopec i te "Cyclohexene Esterification Hydrogenation ki te Tukanga Hou Cyclohexanone". E tata ana te tere whakamahinga ngota waro ki te 100%, ehara i te mea he iti noa te whakamahinga pūngao, engari ka taea hoki te mahi tahi me te whakaputa etanoru tino. Kua oti te rangahau whakamātautau. Ka tere te whakatinanatanga o te mōkihi tukanga 200,000 tāne/tau, me te tono ahumahi 200,000 tāne/tau.

2. Mā te hangarau hou ka kaha te whanaketanga o ngā ahumahi hou, mā te nekehanga me te whakapai ake ka tiakina te awa wai mārama

I ēnei rā, kua riro a Baling Petrochemical hei umanga nui e hono ana i ngā matū petrochemical me te waro, me te umanga hanga caprolactam me te rapa lithium nui rawa atu o te motu, ā, he pūtake hanga kapia epoxy nui hoki. I roto i ēnei, ko te mekameka hua caprolactam kei roto ko te 500,000 tana/tau caprolactam (tae atu ki ngā mahi tahi 200,000 tana), te cyclohexanone 450,000 tana/tau, me te 800,000 tana/tau ammonium sulfate. Kua tutuki i ngā huinga hangarau hou katoa o te hanga matomato Caprolactam te ahunga whakamua hangarau i roto i ngā ahumahi tuku iho. Ehara i te mea he pai ake te taiao, engari kua whakaitihia te tukunga parahanga mō ia hua kotahi mā te 50%, ā, kua whakaitihia te utu hanga kotahi mā te 50%, ā, kua whakaitihia te haumi ki te kaha whakaputa mō ia 10,000 tana ki raro iho i te 150 miriona yuan. Nā te whakahekenga tata ki te 80% kua hua mai he painga ōhanga me te pāpori nui.

Nā te hangarau hou o te hanga caprolactam matomato kua tino whakatairanga i te whanaketanga tere o te caprolactam me ōna ahumahi o raro. Tae noa ki te mutunga o te tau 2019, kua hangaia e Sinopec he maha ngā whare hanga caprolactam i Baling Petrochemical, Zhejiang Baling Hengyi me ētahi atu kamupene, me te tauine whakaputa o te 900,000 tana/tau, e 12.16% o te kaha whakaputa caprolactam o te ao me te kaha whakaputa caprolactam o roto o te 24.39%. I tēnei wā, kua eke te kaha whakaputa caprolactam matomato o tōku whenua ki te 4 miriona tana, kua noho hei kaihanga nui rawa atu o te ao, me te wahanga mākete o te ao neke atu i te 50%, e hanga ana i te 40 piriona yuan ahumahi e puta ake ana, me te akiaki i te whanaketanga kaha o te 400 piriona ahumahi o raro.

I te tau 2020, ka whakarewahia te kaupapa nekehanga me te whakapai ake i te mekameka ahumahi caprolactam a Baling Petrochemical me te haumitanga katoa o te 13.95 piriona yuan ki Hunan Yueyang Green Chemical Industrial Park. Ka whakamahia e te kaupapa he puranga hangarau hou i whakawhanakehia motuhake e Sinopec hei hanga mekameka ahumahi caprolactam 600,000-tana/tau. Ka hangaia te kaupapa hei kaupapa whakaaturanga me te kaupapa paerewa mo te "tiaki i te awa me te wai mārama", te wawahi i te "taiawhio matū o te awa", me te whakatinana i te nekehanga o ngā umanga whakaputa matū morearea i roto i ngā tāone nui e nohoia ana puta noa i te motu.
