Paraan na Pansepsep na Kemikal
Say chemical carbon dioxide absorption et manguusar na chemical reaction ed baetan na chemical reagents tan carbon dioxide pian naapag so carbon dioxide manlapud flue gas. Naala toy CO2 diad pangusar tod property na pigaran chemical reagents pian makareact ed CO2 pian makaporma na compound. Saya so matukoy parad saray aplikasyon ya abeba so CO2 concentrations/partial pressures, a singa say flue gas capture ed saray planta na kuryente ya manpapaandar na karbon, planta na semento, tan planta na asero. Sayan paraan et medyo matatken la, tan wala la ray demonstrasyon ed industriya, anggaman melag so sukat na kagawaan.
Paraan na Pisikal ya Pansepsep
Say pisikal ya panag-absorption et manguusar na kablian ya pigaran pisikal ya solvent et walaan na mas atagey a solubility parad carbon dioxide nen saray arum ya kabiangan na flue gas pian nadampot so inkaapag na carbon dioxide manlapud arum iran kabiangan. Saray proseso na panag-ala ya manguusar na pisikal iran reagents et manunan walad duaran kategorya: say sakey et manguusar na polyethylene glycol dimethyl ether bilang panag-ala na reagent, ya saray kaslakan ya proseso et kaiba lay proseso na Selexol ya ginawa na Union Carbide tan say proseso na NHD ya ginawa na Nanjing Chemical Industry Research Institute ed bansa mi; say sananey et manguusar na methanol bilang capture reagent, ya say kaslakan a proseso et say Rectisol low-temperature methanol wash process ya ginawa nen Linde tan Lurgi ed Germany.
Physicochemical Absorption
Likud ed puron kemikal tan pisikal iran paraan na panag-ala na panag-absorb, wala ray kompanya ya nanggawa na proseso na panag-ala ya uusaren so nanduruman reagents ya mankokombina na kemikal tan pisikal iran reagents. Saya so manguusar ed saray bentaha na performance na parehon paraan tan kabkabat bilang physicochemical absorption capture.
Balon Teknolohiya ed Panag-ala
A. Teknolohiya na Panangibiig na Adsorption
Say teknolohiya na adsorption separation et manguusar na pandumaan na atraksion ed baetan na saray aktibon pasen ed tapew na adsorbent tan nanduruman molekula na gas pian nibiig iray nanduruman kabiangan na gas. Say kapasidad na sakey ya adsorbent ya mangasikaso na gas et kaslakan ya misiglaotan ed espisipikon kalawakan na tapew to; no mas baleg so espisipikon tapew na tapew, mas mabiskeg so kapasidad ton mangasikaso na gas. Kanian, saray adsorbent et kaslakan ya porous iran materyales. Saray kaslakan ya uusaren ya adsorbent et saray molecular sieves, activated carbon, silica gel, tan activated alumina, odino kombinasyon na duara odino masulok nin adsorbent. Ipapanengneng na research ya lapud saray nisipor a kablian na molecular spatial structure tan polarity na carbon dioxide, maslak ed saray adsorbent et walaan na mas baleg ya adsorption capacity parad carbon dioxide nen saray arum ya gas a singa say methane, carbon monoxide, hydrogen, tan nitrogen. Kanian, maslak ed saray adsorbent et nayarin usaren parad pangibiig na carbon dioxide.
B. Teknolohiya na Panangibiig na Adsorption
Say pangibiig ed membrane et sakey a paraan na panag-ala na carbon dioxide ya manguusar na nanduruman permeation rate na nanduruman gas components ed pigaran materyales na membrane. Say manunan kabiangan na teknolohiya na pangibiig ed membrane et say pakabidbiran ed saray materyales na membrane ya walaan na selective permeability ed nanduruman kabiangan na gas; saraya so mabetbet a semi-permeable, aliwan-porous iran membrane. Say iloob na gas ed membrane et ontutumbok ed mekanismo na dissolution-diffusion: saray gas molecules ya aka-adsorb ed sakey a diking na membrane et ontunaw tan onlaok ed membrane diad impluensya na gradient na konsentrasyon, insan on-desorb manlapud biek a diking. Lapud nanduruman gas et walaan na nanduruman dissolution-diffusion rates ed membrane, say pansian na nanduruman gas components et nayarin nadampot.
