Nā kūlana kūʻai o ka waikawa acetic glacial, ka waikawa citric a me nā huahana ʻē aʻe

ʻakika acetic glacial

I kēia pule, ua lawa ka hāʻawi ʻana i ka waika glacial acetic, a loaʻa nā mea hoʻohana i lalo i nā waiwai e like me kā lākou pono paʻa.He palahalaha ka mākeke kiko a i ʻole ka lewa, a ke kū nei nā mea hana i kekahi mau kumu kūʻai.Manaʻo ʻia e hoʻonohonoho nui ʻia ka mākeke acetic acid i kēia pule.Ua pani ʻia ka mea kanu ʻakika glacial acetic a Lunan Chemical no ka mālama ʻana i ka lā 29 ʻOkakopa, a e hoʻoholo ʻia ka manawa hoʻomaka.

ʻakika citric

Ua nāwaliwali a hoʻohui ʻia ka mākeke waikawa citric i kēia manawa.Ua komo mālie ka mākeke kalepa ʻē aʻe i ke kau kiʻekiʻe maʻamau, a loaʻa kekahi hopena kākoʻo i ka ʻoihana, a ua hoʻopau koke ʻia ka waihona ʻoihana.Ua hoʻomaka ka ʻoihana e mālama i kahi pae kūpono.Ua piʻi iki ke kumukūʻai o ke kulina maka, a ua hāʻawi ke kumukūʻai hana i kahi kākoʻo lalo no ke kumukūʻai o ka waikawa citric.Ma ka noʻonoʻo ʻana i ke kūlana hoʻolako a me ke koi a me ka noʻonoʻo o ka upstream a me lalo, ua manaʻo ʻia e hoʻomaikaʻi ke kūʻai ʻana a me ke kūʻai ʻana i ka mākeke waikawa citric i kēia pule, a e hoʻoponopono ʻia ke kumukūʻai.

Ethyl acetate

Ua loli ka mākeke ethyl acetate ma kahi ākea i ka pule i hala.Ua hoʻokuʻu aku nā hale hana nui ma Shandong i nā moku, a ua emi ka lako wahi ma ka mākeke.Manaʻo ʻia e piʻi aʻe ke kumukūʻai ma kahi ākea haiki.

Butyl acetate

Ma ʻOkakopa 28, ua hoʻohui nui ʻia ka mākeke butyl acetate.Hoʻoikaika ʻia e ka hoʻomaikaʻi ʻana o ka mākeke n-butanol i ka hopena pule, ua manaʻo ʻia ka mākeke butyl acetate e holo mahana.

Lehu kopa

ʻO ka pule i hala aku nei, ʻaʻole i loli nui ka mākeke lehu soda kūloko, a ua mālie ke ʻano o ka mākeke kālepa.I kēia mau lā, ua mau ka ukana hana o nā mea hana lehu soda ma kahi kiʻekiʻe, a ua lawa ka lako o nā waiwai.Loaʻa nā kauoha i ka hapa nui o nā mea hana lehu soda.I kēia manawa, hoʻokō ʻia ka hapa nui o nā kauoha mua, a ke waiho nei ka papa inoa o nā mea hana lehu soda ma kahi haʻahaʻa.Ua hoʻokiʻekiʻe ʻia nā kumukūʻai o nā mea hana lehu soda ma Shandong, a ʻaʻole i loli nui nā kumukūʻai o ka lehu soda māmā ma nā wahi ʻē aʻe.He nāwaliwali ka makemake o lalo, a ʻaʻole makemake nui nā mea hoʻohana hope e kūʻai i nā waiwai, no laila pono lākou e makaʻala a nānā i ka mākeke.I ka wā pōkole, hiki ke hoʻokaʻawale ʻia ka mākeke lehu soda kūloko ma kahi ākea.

ʻO ka waiʻawaʻawa

ʻO ka pule i hala aku nei, ua maʻalahi ke kūlana holoʻokoʻa o ka mākeke soda caustic, makaʻala ka poʻe komo i ka mākeke, a ʻo nā kūlana logistic a me nā halihali o nā hale hana ʻĀkau Komohana.ʻO ka hoihoi no ka loaʻa ʻana o nā waiwai ma lalo o ke kahawai, ʻaʻole i nui ka nui, a ke holo mau nei ke kumukūʻai o ka soda caustic no ka wā pōkole i kahi kiʻekiʻe.

Dimethyl carbonate

I ka pule i hala aku nei, ua hāʻule haʻahaʻa ka mākeke ʻoihana ʻenehana dimethyl carbonate.I kēia manawa, ua nāwaliwali ke koi no kekahi mau terminals, a ke mālama nei ke kahawai i ke kūʻai pono ʻana, a ke mau nei ke kaomi ma ka ʻaoʻao hoʻolako.Ua manaʻo ʻia e holomua ke kumukūʻai o ka mākeke DMC kūloko ma kahi haʻahaʻa i kēia lā.

Maleic anhydride

I kēia pule, hiki ke hoʻomau i ka piʻi ʻana o ka maleic anhydride, me ka hoʻoikaika ʻana i lalo i nā kumukūʻai mākeke.Ma ka ʻaoʻao hoʻolako, ʻo ka mālama mua ʻana, ma kahi o 120,000 tons o nā mea hana i kahi hoʻolālā hoʻomaka, a ʻo ka hoʻopuka ʻana o ka maleic anhydride e pau ka hāʻule a hoʻi hou ʻana, e huli mālie ana mai kahi paʻa iki a wehe;

Ma ka ʻaoʻao koi, manaʻo ʻia e nāwaliwali ka noi terminal, a ke koi nei nā ʻoihana resin i lalo e kau inoa i nā kauoha hou.Hiki ke emi ka ukana hoʻomaka a i ʻole ka waihona waiwai, a hiki ke hoʻomau i ka nāwaliwali o ka loaʻa ʻana o ka maleic anhydride.I ka wā pōkole, paʻakikī ke hōʻemi i ke kūʻē ʻana o nā kālepa maleic anhydride ma nā wahi like ʻole, a loaʻa i nā mea kūʻai aku ke hoʻoikaika hou e hoʻololi i nā waiwai no ka nui.
