Aia i loko o ke kinoea maoli i unuhi ʻia kekahi nui o ke kinoea acidic CO2, hiki ke hoʻoulu i nā pilikia e like me ka emi ʻana o ka waiwai calorific a me ka ʻino o ka pipeline. No laila, koi ʻia ka mālama decarbonization ma mua o ka lawe ʻana a me ka hoʻohana ʻana i ka pipeline.
E like me ke kinoea kūlohelohe kumu waiwai calorific i loko o ka national standard (GB/T 11062-2014), hiki ke helu ia 10mol% CO2 e ho'ēmi i kahi o 9.80% i ka methane calorific waiwai no ka cubic mika. I ka noho pū ʻana o CO2 me ka mahu wai a loaʻa ke kaomi ʻāpana ʻoi aku ka nui ma mua o 207kPa, e hoʻopōʻino nui ia i nā mea hana a me nā paipu, a pono e lawe ʻia nā hana anti-corrosion hou. No laila, pono ke kinoea maoli e hoʻopau i ka CO2 ma mua o ka lawe ʻia ʻana i nā pipeline kalepa.
Hoʻohana ʻia ke kaʻina hana MDEAe wehe i ka CO2 mai ke kinoea maoli.
Nā waiwai MDEA Physicochemical a me ke kumu decarburization
ʻO MDEA, ka inoa ʻepekema N -methyldiethanolamine, he wai ʻeleʻele ʻole a melemele iki paha.
Huina mole: CH3N(CH2CH2OH)2 ,
Puni paila: 246~249 ℃ /760mmhg ; 'umekaumaha kiko'ī: 1.0425g/ml (20 ℃);
Wehe hau: -21 ℃ (maemae 99%); viscosity: 101Cp (20 ℃);
Hiki ke maʻalahi me ka wai, ethanol, ether, etc.; alkaline nawaliwali i ka wai; E hiki mai ana ka hopena kemika i loko o ka waikawa carbon dioxide a me ke kinoea hydrogen sulfide, a ma ke kaomi kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ke kinoea carbon dioxide a me ke kinoea hydrogen sulfide No laila ʻo ke kaʻina holoʻokoʻa holoʻokoʻa ke kaʻina hana kino a me ke kaʻina.
ʻO ka wai momona MDEA ma hope o ke komo ʻana i ka hydrogen sulfide a me ka carbon dioxide e komo i loko o ka pahu uila no ka hoʻoheheʻe ʻana o ka uila, a laila hoʻouna ʻia i ka hale kiaʻi hou. Hoʻomaʻamaʻa ʻia ka wai waiwai a hoʻoheheʻe ʻia ma ka lalo o ka hale kiaʻi e hoʻokuʻu loa i ke kalapona a me ka hydrogen sulfide. I ka manawa like, piʻi ke kinoea ma lalo o ka hale kiaʻi e hana i kahi hopena wehe lua ma luna o ka wai waiwai ma luna o ka hale kiaʻi.; no laila, ʻo ke kaʻina hana hou a pau, ʻo ia ke kaʻina hana hou kino a me ke kemika. ʻO ka hopena kemika kikoʻī penei:
R2R'N + H2S R2R'NH +HS (pane koke)
R2R'N+CO2+ H2O R2R'NH +HCO3 (ka hopena lohi)
Hoʻomaʻamaʻa ʻo Rongteng i ka hoʻomaʻamaʻa ʻana i ke poʻo o ke kinoea,hoʻomaʻemaʻe kinoea maoli, LPG ho'ōla hou,Mea kanu LNGahoʻonohonoho kinoea kinoea.
