I ʻOkakopa, ua ʻike ka mākeke acetone ma Kina i ka emi ʻana o nā kumukūʻai huahana i luna a i lalo, me ka liʻiliʻi o nā huahana e ʻike i ka piʻi ʻana o ka nui. ʻO ke kaulike ʻole ma waena o ka hoʻolako ʻana a me ka noi a me ke koʻikoʻi o ke kumukūʻai ua lilo i kumu nui e emi ai ka mākeke. Mai ka hiʻohiʻona o ka loaʻa kālā nui, ʻoiai ua piʻi iki nā huahana o luna, ʻoi aku ka nui o ka loaʻa kālā ma nā huahana o lalo. Manaʻo ʻia ʻo Nowemapa, pono e nānā pono ke kaulahao ʻoihana acetone upstream i ka hāʻawi ʻana a me ke koi ʻana i ke kūlana pāʻani, a hiki i ka mākeke ke hōʻike i kahi ʻano o ka fluctuating a nāwaliwali ka hana.

I ka mahina o ʻOkakopa, ua hōʻike ʻia ke ʻano o ka hāʻule ʻana a i ʻole ka piʻi ʻana o nā kumukūʻai o ka acetone a me nā huahana ma nā kaulahao ʻoihana i luna a me lalo. Ma keʻano kikoʻī, hoʻonui nā kumukūʻai o ka acetone a me MIBK i kēlā me kēia mahina, me ka piʻi ʻana o 1.22% a me 6.70%, kēlā me kēia. Eia naʻe, ua emi nā kumu kūʻai maʻemaʻe o ka benzene maʻemaʻe i luna, propylene, a me nā huahana o lalo e like me bisphenol A, MMA, a me isopropanol i nā pae like ʻole. ʻO ke kaulike ʻole ma waena o ka hāʻawi ʻana a me ke koi a me ke koʻikoʻi o ke kumukūʻai i lilo i kumu nui e hoʻemi ai i ke kumukūʻai.

Mai ka manaʻo o ka awelika o ka waiwai nui, ʻo ka awelika o ka loaʻa kālā o ka benzene maʻemaʻe maʻemaʻe a me ka propylene ma ʻOkakopa i kokoke i ka laina loaʻa a me ka poho, me ka maikaʻi o kekahi a ʻo ka maikaʻi ʻole kekahi. Ma ke ʻano he huahana waena i ke kaulahao ʻoihana, ua hoʻololi ʻo acetone i kāna kikowaena kumukūʻai ma muli o ke kākoʻo paʻa a me ke kākoʻo kumu kūʻai. I ka manawa like, ua emi iho ke kumu kūʻai o ka phenol a hoʻihoʻi hou ʻia, ma kahi o 13% ka piʻi ʻana o ka waiwai nui o nā hale hana phenol ketone i hoʻohālikelike ʻia i ka mahina i hala. Eia naʻe, i loko o nā huahana downstream, koe no ka awelika waiwai nui o bisphenol A ma lalo o ka waiwai a me ka poho laina, ka awelika kumu waiwai o MMA, isopropanol, a me MIBK i nā mea a pau ma luna o ka loaʻa a me ka poho laina, a me ka MIBK ka waiwai nui, me ka malama ma ka mahina mahuahua o 22.74%.

Manaʻo ʻia ʻo Nowemapa, hiki i nā huahana kaulahao acetone ke hōʻike i kahi ʻano hana nāwaliwali a paʻakikī. No laila, pono e nānā pono i nā loli o ka lako a me ka noi, a me ke alakaʻi ʻana i nā nūhou mākeke, ʻoiai e nānā pono ana i nā loli a me ka ikaika o ka hoʻouna ʻana i ke kumukūʻai.
