1. Butadiene
Ke holo nei ka lewa makeke, a ke piʻi mau nei nā kumukūʻai
Ua hoʻokiʻekiʻe ʻia ke kumukūʻai hoʻolako o ka butadiene i kēia manawa, ʻoi aku ka ikaika o ka mākeke kālepa, a ke hoʻomau nei ke kūlana hemahema i ka wā pōkole, a ikaika ka mākeke. Eia naʻe, me ka piʻi ʻana o ka ukana o kekahi mau mea hana a me ka hoʻokō ʻana i ka mana hana hou, aia ka manaʻolana o ka hoʻonui ʻana o ka lako i ka mākeke e hiki mai ana, a ua manaʻo ʻia ka mākeke butadiene e kūpaʻa akā nāwaliwali.
2. Methanol
Kākoʻo nā kumu kūpono i ka mākeke e piʻi kiʻekiʻe
Ke piʻi nei ka mākeke methanol i kēia mau lā. Ma muli o ka hoʻololi ʻana i nā keʻena nui ma ka Hikina Waena, manaʻo ʻia e emi ka nui o ka lawe ʻana mai o ka methanol, a ua komo mālie ka waihona methanol ma ke awa i ke kahawai destocking. Ma lalo o ka haʻahaʻa haʻahaʻa, paʻa nui nā ʻoihana i nā kumukūʻai no ka moku ukana; ʻO ka makemake o lalo e mālama i ka manaʻolana o ka ulu ulu. Manaʻo ʻia e ikaika a paʻakikī ka mākeke kiko methanol kūloko i ka wā pōkole.
3. Methylene Chloride
Ke hāʻule nei ke ʻano o ka mākeke pāʻani hoʻolako a koi
Ua hāʻule ke kumukūʻai makeke o dichloromethane i kēia manawa. Ua mālama ʻia ka ukana hana o ka ʻoihana i loko o ka pule, a ua mālama ka ʻaoʻao koi i nā kūʻai paʻa. Ua nāwaliwali ka lewa kālepa makeke, a ua hoʻonui ʻia nā waihona ʻoihana. I ka hoʻokokoke ʻana o ka hopena o ka makahiki, ʻaʻohe mea kūʻai nui, a ikaika ka manaʻo kali-a-ʻike. Manaʻo ʻia e holo mālie ka mākeke dichloromethane i ka wā pōkole.
4. Isooctyl alcohol
Nā kumu waiwai nāwaliwali a hāʻule nā kumukūʻai
Ua hāʻule ke kumukūʻai o isooctanol i kēia manawa. Loaʻa nā ʻoihana isooctanol nui i ka hana paʻa, lawa ka lako holoʻokoʻa o ka isooctanol, a aia ka mākeke i ka wā o waho, a ʻaʻole lawa ka noi o lalo. Manaʻo ʻia e loli ke kumukūʻai o isooctanol a hāʻule i ka wā pōkole.
