Rot bilong Putim ol Kemikel
Kemikel kabon daioksait absorpsen i yusim kemikel riaksen namel long ol kemikel riajen na kabon daioksait long separetim kabon daioksait long 'flue gas'. Em i save kisim CO2 long rot bilong yusim ol samting bilong sampela kemikel 'reagents' long wok wantaim CO2 long kamapim ol 'compound'. Em i gutpela long ol wok we i gat liklik CO2 konsentresen/hap presa, olsem kisim 'flue gas' insait long ol pawa plent we i save kukim ston kol, ol simen plent, na ol steel plent. Dispela rot em i gutpela tru, wantaim ol indastriel demonstresen i stap pinis, maski skel bilong ol ikwipmen i liklik.
Rot bilong kisim wara long bodi
'Pysical absorption capture' i yusim dispela samting olsem sampela 'physical solvents' i gat bikpela 'solubility' long 'carbon dioxide' winim ol narapela samting insait long 'flue gas' bilong mekim wok bilong rausim kabon daioksait long ol narapela samting. Ol wok bilong kisim ol samting we ol i yusim ol 'physical reagents' i save pundaun long tupela lain: wanpela i yusim 'polyethylene glycol dimethyl ether' olsem 'capture reagent', wantaim ol wok we i save kamap olsem Selexol we Union Carbide i kamapim na NHD proses we Nanjing Chemical Industry Research Institute long kantri bilong mi i kamapim; narapela i yusim methanol olsem 'capture reagent', wantaim wanpela kain proses em Rectisol low-temperature methanol wash proses we Linde na Lurgi long Jemani i bin kamapim wantaim.
Fisikokemikel Absopsen
Antap long ol rot bilong kisim ol samting long rot bilong kemikel na fisikel absopsen tasol, sampela kampani i bin kamapim ol rot bilong kisim ol samting we ol i yusim ol miks 'reagents' we i bungim ol kemikel na 'physical reagents'. Dispela i helpim ol gutpela wok bilong tupela rot na ol i kolim olsem 'physicochemical absorption capture'.
Ol nupela teknoloji bilong kisim piksa
A. Adsorption Seperesen Teknoloji
Adsorption separation technology i yusim difrens long atraksen namel long ol ektiv sait long adsorbent pes na ol narapela narapela ges molekiul long separetim ol narapela narapela ges komponen. Pasin bilong wanpela 'adsorbent long holim ges' i save kamap long 'surface area' bilong en; bikpela spes eria, strongpela ges handeling kapasiti. Olsem na, ol 'adsorbents' em ol samting we i gat hul long en. Ol 'adsorbents' we ol i save yusim planti taim em ol 'molecular sieves', 'activated carbon', 'silica gel', na 'activated alumina', o tupela o moa 'adsorbents' wantaim. Risets i soim olsem bikos long ol samting we i stap insait long 'molecular spatial structure' na 'polarity' bilong 'carbon dioxide', planti 'adsorbents' i gat bikpela 'adsorption capacity' bilong 'carbon dioxide' winim ol narapela ges olsem 'methane', 'carbon monoxide', 'hydrogen', na 'nitrogen'. Olsem na, planti 'adsorbents' ol i ken yusim long rausim 'carbon dioxide'.
B. Adsorption Seperation Technology
Membrane separation em i wanpela rot bilong kisim kabon daioksait we i yusim ol narapela narapela 'permeation rates' bilong ol narapela narapela ges komponen insait long sampela 'membrane materials'. As bilong 'membrane separation' teknoloji em long luksave long ol 'membrane materials' we i gat 'selective permeability' long ol narapela narapela ges komponen; planti taim ol dispela em ol 'semi-permeable, non-membrane. Gas permeation insait long membrane i bihainim wanpela dissolution-diffusion mechanism: ol ges molekiul we i pas long wanpela sait bilong membrane i save kapsait na go insait long membrane aninit long strong bilong konsentresen gradient, na bihain ol i save lusim narapela sait. Bikos ol narapela narapela ges i gat ol narapela narapela 'diffusion rates' insait long 'membrane', ol i ken mekim wok bilong seperetim ol narapela narapela hap bilong ges.
