nā mea maka nui no ka hana ʻana i ka styrene

ʻO nā kumu waiwai nui no ka hana ʻana i ka styrene he polymerized grade ethylene a me ka benzene maʻemaʻe, a ʻo ka benzene maʻemaʻe he 64% o ke kumu kūʻai o ka styrene.ʻO ka hoʻololi hoʻokahi o ka styrene a me kāna kumu kumu kumu kūʻai benzene maʻemaʻe e hopena nui i ka hana ʻoihana o ka ʻoihana.ʻO ke kumu kūʻai o ka benzene maʻemaʻe ka hopena nui i ke kumu kūʻai o styrene.I kēia manawa, loa'a mai ka benzene ma'ema'e mai ka māhā o ka aila, no laila ke kumu kū'ai o ka aila ma'ema'e ke kumu kū'ai o benzene ma'ema'e.Ua piʻi aʻe nā kumukūʻai aila ʻaila i nā makahiki i hala iho nei, e alakaʻi ana i nā kumukūʻai kiʻekiʻe o ka benzene maʻemaʻe.Eia nō naʻe, me ka ʻāpana kūloko o nā ʻoihana kemika lanahu e hoʻolauna i ka ʻenehana hana kiʻekiʻe o ka hoʻomaʻemaʻe ʻana i ka lanahu crude benzol, e hana i nā hōʻailona e hoʻokō i ʻoi aku ka nui ma mua o ka petroleum benzene i hoʻomaʻemaʻe ʻia benzene. ʻO ka petroleum benzene, nā kumukūʻai benzene maʻemaʻe a me nā kumukūʻai aila hiki ke alakaʻi i kekahi deviation, a hoʻohaʻahaʻa i ke kumukūʻai makeke o ka benzene maʻemaʻe.
