Ukuhlukaniswa kweMembrane - Ukuthola ukwehlukaniswa kwekhabhoni dioxide kugesi yemvelo
Ukuchazwa Komkhiqizo
Okuqukethwe okuphezulu kwe-CO2 kugesi yemvelo kungaholela ekungathembekeni kwegesi yemvelo ukuthi kusetshenziswe ngabakhiqizi be-turbine noma ama-compressors, noma kubangele izinkinga ezingaba khona njengokugqwala kwe-CO2. Kodwa-ke, ngenxa yesikhala esilinganiselwe nomthwalo, ukumuncwa kwendlela okuwumdabu kanye namadivayisi wokuvuselelwa kabusha njengamadivayisi wokungena a-Amine awakwazi ukufakwa kumapulatifomu aphesheya. Kumadivayisi we-catalyst adsortion, njengamadivayisi we-PSA, imishini inevolumu enkulu futhi ayiphatheki kakhulu ukufaka nokuhamba. Futhi kudinga indawo enkulu efanelekile okufanele ihlelwe, futhi ukusebenza kahle kokususa ngesikhathi sokusebenza kukhawulelwe kakhulu. Ukukhiqizwa okulandelayo kudinga ukushintshwa okujwayelekile kwama-catalysts agcwele ama-adsorbed, okuholele ezindlekweni ezengeziwe zokusebenza, amahora wesondlo nezindleko. Ukusetshenziswa kobuchwepheshe bokuhlukaniswa kwe-membrane akukwazi ukususa kuphela i-CO2 kugesi yemvelo, kunciphisa kakhulu ivolumu yalo nesisindo, kepha futhi kunemishini elula, ukusebenza okulula nokugcinwa, nezindleko eziphansi.
Ubuchwepheshe bokuhlukaniswa kwe-membrane busebenzisa ukukhiqizwa kwe-CO2 ezintweni ezithile ze-membrane ngaphansi kwengcindezi ethile yokuvumela igesi yemvelo ecebile kwi-CO2 ukudlula kwizakhi ze-membrane, bese uqongelela i-CO2 ngaphambi kokuba ikhishwe. Igesi engenakuqhathaniswa yemvelo kanye nenani elincane le-CO2 lithunyelwa njengegesi yomkhiqizo kubasebenzisi be-Downstream, anjenge-turbines ye-CO2 ngokuvumelanisa kwengcindezi yemvelo ngokuvumelanisa kwemvelo, noma ngokuqukethwe kwe-CO2 kumkhiqizo kungalungiswa ngokuya nge-inlet ehlukile Amagesi, futhi ngaso sonke isikhathi ahlangabezana nezidingo zenqubo.
