Indlela yokufunxa imichiza
Ukufunxwa kweekhemikhali zekharbon diokside kusebenzisa ukusabela kweekhemikhali phakathi kwe-reagents yeekhemikhali kunye ne-carbon dioxide ukwahlula i-carbon dioxide kwi-flue gas. Ibamba i-CO2 ngokuxhamla ipropati yee-reagents ezithile zeekhemikhali ukuba ziphendule nge-CO2 ukwenza iikhompawundi. Ilungele usetyenziso olunoxinzelelo oluphantsi lwe-CO2/uxinzelelo oluyinxenye, olufana nokubanjwa kwerhasi yombane kwizityalo zamandla ezitshisiweyo zamalahle{5}}, kwizityalo zesamente, kunye nezityalo zentsimbi. Le ndlela ikhulile, kunye nemiboniso yemizi-mveliso ekhoyo, nangona isikali sezixhobo sincinci.
Indlela yokufunxa ngokwaseMzimbeni
Ukubamba ukufunxa ngokwasemzimbeni kusebenzisa ipropati yokuba izinyibilikisi ezithile zomzimba zinokunyibilika okuphezulu kakhulu kwekharbhon diokside kunamanye amacandelo erhasi yeflue ukuphumeza ukwahlulwa kwekharbon diokside kwamanye amacandelo. Iinkqubo zokubamba usebenzisa ii-reagents ezibonakalayo ziwela kakhulu kwiindidi ezimbini: enye isebenzisa i-polyethylene glycol dimethyl ether njenge-reagent yokubamba, kunye neenkqubo eziqhelekileyo ezibandakanya inkqubo ye-Selexol eyenziwe yi-Union Carbide kunye nenkqubo ye-NHD ephuhliswe yiNanjing Chemical Industry Research Institute kwilizwe lam; enye isebenzisa i-methanol njengendawo yokubamba, nenkqubo eqhelekileyo yiRectisol ephantsi{1}}inkqubo yokuhlamba i-methanol yobushushu edityaniswe nguLinde kunye noLurgi eJamani.
Ukufunxwa kwePhysicochemical
Ngaphandle nje kweendlela zokubamba imichiza kunye neyomzimba, ezinye iinkampani ziye zaphuhlisa iinkqubo zokubamba zisebenzisa ii-reagents ezixubeneyo ezidibanisa imichiza kunye ne-reagents yomzimba. Oku konyusa iingenelo zokusebenza kuzo zombini iindlela kwaye kwaziwa ngokuba yiphysicochemical absorption capture.
IiTekhnoloji zokuThatha iNoveli
A. Itekhnoloji yokwahlula iAdsorption
Itekhnoloji yokwahlula i-Adsorption isebenzisa umahluko phakathi komtsalane phakathi kweesayithi ezisebenzayo kumphezulu we-adsorbent kunye neemolekyuli zegesi ezahlukeneyo ukwahlula amacandelo ahlukeneyo egesi. Umthamo wokuphatha igesi ye-adsorbent ngokubanzi inxulumene nommandla wayo othile; Ubukhulu bendawo ethile yomhlaba, amandla okuphatha igesi yomelele. Ke ngoko, ii-adsorbents ngokuqhelekileyo zizinto ezirhabaxa. Ii-adsorbents ezisetyenziswa ngokuqhelekileyo ziquka i-molecular sieves, i-carbon activated, i-silica gel, kunye ne-alumina esebenzayo, okanye indibaniselwano yee-adsorbents ezimbini okanye ngaphezulu. Uphando lubonisa ukuba ngenxa yeepropathi zendalo ze-carbon dioxide's spatial structure kunye ne-polarity, ii-adsorbents ezininzi zine-adsorption enkulu ye-carbon dioxide kunezinye iigesi ezifana ne-methane, i-carbon monoxide, i-hydrogen kunye ne-nitrogen. Ngoko ke, ii-adsorbents ezininzi zingasetyenziselwa ukuhlukana kwe-carbon dioxide.
B. Itekhnoloji yokwahlula iAdsorption
Ukwahlulwa kweMembrane yindlela yokubamba ikharbon diokside esebenzisa amanqanaba ahlukeneyo okutyhubela amacandelo erhasi ahlukeneyo kwizinto ezithile zemembrane. Undoqo wetekhnoloji yokwahlula i-membrane uchonga izixhobo ze-membrane ezinokungena okukhethiweyo kumacandelo ahlukeneyo egesi; ezi zihlala zi semi{1}}zingena ngaphakathi, aziyi{2}}inwebu ezidumbileyo. Ukugqobhoza kwerhasi kwimembrane kulandela ukunyibilika{4}}indlela yokusasaza: iimolekyuli zerhasi ezidityaniswe kwelinye icala lenwebu zinyibilike kwaye zisasazeke kwinwebu phantsi kweempembelelo zeconcentration gradient, emva koko idize kwelinye icala. Ngenxa yokuba iirhasi ezahlukeneyo zinokunyibilika okwahlukileyo{6}}kumazinga okusasazwa kwinwebu, ukwahlulwa kwezinto ezahlukeneyo zerhasi kunokuphunyezwa.
