Aia i loko o ke kinoea kūlohelohe i unuhi ʻia kahi nui o ke kinoea ʻakika CO2, hiki ke hana i nā pilikia e like me ka emi ʻana o ka waiwai calorific a me ka pala o ka pipeline. No laila, pono ka mālama decarbonization ma mua o ka lawe ʻana a me ka hoʻohana ʻana i ka pipeline.
Wahi a ke ʻano hoʻohālikelike o ke kumukūʻai calorie kinoea kūlohelohe ma ke kūlana aupuni (GB/T 11062-2014), hiki ke helu ʻia he 10mol% CO2 e hōʻemi ana ma kahi o 9.80% o ka waiwai calorie methane no kēlā me kēia mika cubic. Ke hui pū ʻo CO2 me ka mahu wai a he ʻoi aku ka nui o ke kaomi hapa ma mua o 207kPa, e hōʻino nui ia i nā lako a me nā paipu, a pono e hana ʻia nā hana anti-corrosion hou aʻe. No laila, pono e wehe pono ʻia ke kinoea kūlohelohe ma mua o ka lawe ʻia ʻana i nā paipu kalepa.
Hoʻohana ʻia ke kaʻina hana MDEA e wehe i ka CO2 mai ke kinoea kūlohelohe.
Nā waiwai MDEA Physicochemical a me ke kumumanaʻo decarburization
ʻO MDEA, ka inoa ʻepekema ʻo N-methyldiethanolamine, he wai ʻālohilohi kala ʻole a melemele iki paha.
ʻO ke ʻano molekole: CH3N(CH2CH2OH)2,
Kikowaena paila: 246~249 ℃ /760mmhg; umekaumaha kikoʻī: 1.0425g/ml (20 ℃);
Kiko hau: -21 ℃ (maʻemaʻe 99%); mānoanoa: 101Cp (20 ℃);
Hiki ke hui pū ʻia me ka wai, ethanol, ether, a pēlā aku; nāwaliwali ka alkaline i ka wai; e hana ʻia ka hopena kemika i loko o ka waikawa kalapona dioxide a me ke kinoea hydrogen sulfide, a ma ke kaomi kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ke kalapona dioxide a me ke kinoea hydrogen sulfide. No laila, ʻo ke kaʻina hana omo holoʻokoʻa ke kaʻina hana omo kino a me ke kemika.
Ma hope o ka omo ʻana i ka hydrogen sulfide a me ke kalapona ʻokikene, komo ka wai momona MDEA i loko o ka pahu uila no ka hoʻoheheʻe ʻana o ka vacuum flash, a laila hoʻouna ʻia i ka hale kiaʻi hana hou. Hoʻomehana ʻia ka wai momona a hoʻoheheʻe ʻia ma ka lalo o ka hale kiaʻi e hoʻokuʻu loa i ke kalapona ʻokikene a me ka hydrogen sulfide. I ka manawa like, piʻi aʻe ke kinoea ma ka lalo o ka hale kiaʻi e hana i kahi hopena wehe lua ma ka wai momona ma ka piko o ka hale kiaʻi.; no laila, ʻo ke kaʻina hana hou holoʻokoʻa 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 (loli ka pane ʻana)
He loea ʻo Hengzhong i ka mālama ʻana i ke poʻo luawai o ke kahua kinoea, hoʻomaʻemaʻe kinoea kūlohelohe, hoʻōla LPG, Hale hana LNG a me hoʻonohonoho mīkini hana kinoea kūlohelohe.
