1. ʻAʻole waihoʻoluʻu ʻo DGA, ʻaʻohe wai liʻiliʻi me kahi ala amine mālie.Hiki ke hui pū ʻia ka DGA me ka wai, nā waiʻona, a me nā hydrocarbons ʻala, akā ʻAʻole hiki ke hoʻopili ʻia me ka aliphatic hydrocarbons a me ka ethyl ether. Isometric me diethanolamine; akā naʻe, ʻoi aku ka hana o ka hui H2N mua. C4H11NO2 NĀ PALAPALA • Hoʻohana ʻia no ka wehe ʻana o carbonyl sulfide (COS) mai ka wai nā kahawai hydrocarbon • Hoʻohana 'ia e like me ka wae'ūheheʻe koho no ka ho'ōla 'ana o aromatics mai nā kahawai hoʻoheheʻe • Wehe i ke kalapona (CO2) a me ka hydrogen sulfide (H2S) mai ke kinoea maoli a me ka hoʻoheheʻe ʻana, nā wai wai hydrocarbon aliphatic a me nā mea ʻawaʻawa ʻē aʻe mokuahi hydrocarbon. • Ka hoʻomākaukauʻana i nā mea hoʻopalekana foam, pulu a me nā mea emulsifying, nā polymers condensation, nā mea wehe kiʻi photoresist, a me nā amides no ka mālama pilikino a me nā mea hana metala. 2. Amine kinoea lapaʻau, no hoi i ike i ka amine scrubbing, kinoea ka mea ʻono a me ka wehe ʻana i ke kinoea waikawa, pili i kahi hui o nā kaʻina hana e hoʻohana ai i ka wai wai o nā alkylamines like ʻole (i ʻōlelo pinepine ʻia me nā amine) e wehe i ka hydrogen sulfide (H 2 S) a me carbon dioxide (CO 2) mai nā kinoea. [3] He kaʻina hana maʻamau i hoʻohana ʻia i loko o nā refineries, a hoʻohana pū ʻia i nā mea kanu petrochemical, kūlohelohe nā mea hana kinoea a me nā ʻoihana ʻē aʻe. Nā kaʻina hana i loko o nā mea hoʻoheheʻe aila a i ʻole nā mea kanu hana kemika ʻO ka mea e wehe ai i ka hydrogen sulfide i kapa ʻia ʻo "sweetning" nā kaʻina hana no ka mea ʻo ke ʻala o nā huahana i hoʻoponopono ʻia hoʻomaikaʻi ʻia e ka nele o ka hydrogen sulfide. ʻO kahi koho i ka hoʻohana ʻana i nā amine e pili ana i ka ʻenehana membrane. Eia naʻe, ʻAʻole maikaʻi ka wehe ʻana o ka membrane ma muli o ke ʻano kiʻekiʻe a me nā koina hana a me nā ʻenehana ʻē aʻe kumu. [4] Nui nā amine i hoʻohana ʻia i ka mālama kinoea: Diethanolamine (DEA) Monoethanolamine (MEA) Methyldiethanolamine (MDEA) Diisopropanolamine (DIPA) Aminoethoxyethanol (Diglycolamine) (DGA) ʻO nā amine i hoʻohana pinepine ʻia i nā mea kanu ʻoihana nā alkanolamines DEA, MEA, a me MDEA. ʻO kēia mau amine kekahi hoʻohana ʻia i loko o nā hale hoʻoheheʻe aila he nui e wehe i nā kinoea mai ka wai nā hydrocarbons e like me ke kinoea liquified petroleum (LPG). | |
