1. Butadiene
Ua ikaika ka lewa mākeke, a ke piʻi mau nei nā kumukūʻai
Ua hoʻokiʻekiʻe ʻia ke kumukūʻai lako o ka butadiene i kēia manawa, ua ʻano ikaika ka lewa kālepa mākeke, a ke hoʻomau nei ke kūlana nele o ka lako i ka wā pōkole, a ua ikaika ka mākeke. Eia nō naʻe, me ka hoʻonui ʻia o ka ukana o kekahi mau mea hana a me ke kauoha ʻana o ka mana hana hou, aia kahi manaʻo e hoʻonui ʻia ka lako ma ka mākeke e hiki mai ana, a ua manaʻo ʻia ka mākeke butadiene e paʻa akā nāwaliwali.
2. Methanol
Kākoʻo nā mea maikaʻi i ka mākeke e piʻi aʻe
Ke piʻi nei ka mākeke methanol i kēia mau lā iho nei. Ma muli o nā loli i nā hale hana nui ma ka Hikina Waena, manaʻo ʻia e emi iho ka nui o ka methanol i lawe ʻia mai, a ua komo mālie ka waihona methanol ma ke awa i ke kahawai destocking. Ma lalo o ka waihona haʻahaʻa, mālama nui nā ʻoihana i nā kumukūʻai e hoʻouna i nā waiwai; mālama ke koi ma lalo i ka manaʻolana o ka ulu iki ʻana. Manaʻo ʻia e ikaika a loli ka mākeke methanol kūloko i ka wā pōkole.
3. Methylene Chloride
Hāʻule ke ʻano o ka mākeke pāʻani lako a me ke koi
Ua hāʻule ke kumukūʻai mākeke o ka dichloromethane i kēia mau lā iho nei. Ua mālama ʻia ka ukana hana o ka ʻoihana i ka pule, a ua mālama ka ʻaoʻao koi i nā kūʻai paʻa. Ua nāwaliwali ke ʻano kālepa mākeke, a ua piʻi aʻe nā waihona o nā ʻoihana. I ka hoʻokokoke ʻana mai o ka hopena o ka makahiki, ʻaʻohe waihona nui, a ua ikaika ka manaʻo kali a ʻike. Manaʻo ʻia e hana nāwaliwali a paʻa ka mākeke dichloromethane i ka wā pōkole.
4. ʻO ka waiʻona Isooctyl
Nā kumu waiwai nāwaliwali a me ka hāʻule ʻana o nā kumukūʻai
Ua hāʻule ke kumukūʻai o ka isooctanol i kēia manawa. Loaʻa i nā ʻoihana isooctanol nui ka hana paʻa o nā lako, ua lawa ka lako holoʻokoʻa o ka isooctanol, a aia ka mākeke i ke kau ʻole, a ʻaʻole lawa ke koi ma lalo. Manaʻo ʻia e loli a hāʻule ke kumukūʻai o ka isooctanol i ka wā pōkole.
