ʻO ka Ethylene Glycol Hydration pololei o ka Ethylene Oxide.

ʻEtilena GlikolaNā Alanui i hoʻokumu ʻia ma ka ʻaila a me ko lākou mau manaʻolana
ʻO Ethylene glycol, i ʻike ʻia hoʻi ʻo glycol, he mea maka organik koʻikoʻi ia i ka ʻoihana petrochemical. Ma muli o ke kumukūʻai loli o ka ʻaila i kēia lā, ua lilo ka loaʻa ʻana o kahi ala waiwai no ka hana ʻana i ka ethylene glycol i wahi noiʻi. Hoʻopili kēia pepa a hoʻohālikelike i nā ala i hana ʻia ma ka ʻaila a me nā ala ʻaʻole i hana ʻia ma ka ʻaila no ka hana ʻana i ka ethylene glycol, a nānā i ko lākou mau pono a me nā hemahema.

ʻO kēia ke ʻano kuʻuna no ka hana ʻana i ka ethylene glycol nui. Ma kēia kaʻina hana, ua hui pū ʻia ka ethylene oxide a me ka wai ma kahi ratio molar o 1:20 a i 1:22. Hoʻopau piha ka ethylene oxide e hana i kahi hui maka, a laila ua hoʻokomo ʻia i nā evaporation he nui no ka dehydration a me ka vacuum fractionation e loaʻa ai ka ethylene glycol, me nā huahana ʻaoʻao e like me ka diethylene glycol a me ka triethylene glycol. ʻO ka huina o ka hua ma kahi o 88%.

ʻO ka hoʻonui ʻana i ka nui o ka wai hiki ke hōʻemi i ka hoʻokumu ʻia ʻana o nā huahana ʻaoʻao a hoʻomaikaʻi i ka helu hoʻololi o ka ethylene oxide. Eia nō naʻe, ʻo ka nui o ka wai i hoʻokomo ʻia e hana i nā pilikia koʻikoʻi i ka loaʻa ʻana o nā huahana maʻemaʻe kiʻekiʻe. Eia kekahi, pono nā lako hana no kēia kaʻina hana i nā evaporators he nui, a nui ka ikehu i hoʻopau ʻia no ka hoʻokaʻawale ʻana i ka huahana, e hopena ana i kahi kaʻina hana me ke kahe lōʻihi, ka hoʻopukapuka lako kiʻekiʻe, a me ka hoʻohana ikehu kiʻekiʻe.
