Incazelo Yemikhiqizo
Uhlelo lokuhlukanisa ulwelwesi lwe-hydrogen (olwaziwa nangokuthi iyunithi yokuhlanza ulwelwesi lwe-hydrogen) iyisethi ephelele yezinto zokusebenza ezihlanganisa ukwelapha kusengaphambili kwegesi, ukuhlukaniswa kolwelwesi, kanye nokuzinza kwegesi yomkhiqizo.
Umgomo wayo oyinhloko ukusebenzisa i-fibre engenalutho noma{0}}ulwelwesi lwe-polymer yeshidi (isb, i-polyimide, i-polysulfone{3}}izinto ezisekelwe) ezinokukhetha okuphezulu kwe-hydrogen{4}ngaphansi komehluko othile wengcindezi, ama-molecule e-hydrogen (isisindo samangqamuzana amancane, amandla e-kinetic aphezulu) angena ezimbotsheni ze-membrane ngokushesha kunamanye ama-gas, ama-molecule e-NCHℂ.
Ingakhiqiza ngokuzinzile-i-hydrogen ehlanzekile futhi ingenye yezinto ezisetshenziswayo zokuthola kabusha i-hydrogen ngempumelelo kanye nokuhlanza embonini{1}}yekhabhoni hydrogen ephansi.
Isimiso sokusebenza
Inqubo yokusebenza ye-Hydrogen Separation Membrane ingafingqwa njengezinyathelo ezinhlanu ezibalulekile: i-hydrogen-igesi ecebile yokwelashwa kusengaphambili → ukulawulwa kokucindezela → ukuhlukaniswa kolwelwesi → ukuzinza kwegesi (i-hydrogen) → ukukhishwa kwegesi ebuyiselwayo (ukungcola)
I-Hydrogen-rich gas pretreatment:Igesi ecebile ye-hydrogen-(isb., ukuhluza igesi-eno-30-70% H₂, igesi yemvelo elungisa igesi eno-70-90% H₂) ingena kuqala ohlelweni lokwelapha kusengaphambili. Idlula ngesihlungi esihlanganisayo ukuze ikhiphe amaconsi awuketshezi (amanzi, uwoyela) anosayizi wezinhlayiyana Omkhulu noma olingana no-1 μm, bese ifaka isihlungi sezinhlayiyana ukuze kuqedwe ukungcola okuqinile (uthuli, izinhlawulo ze-catalyst) ngosayizi wezinhlayiyana Omkhulu noma olingana no-0.1 μm-ukugwema ukuvinjelwa kwe-membrane pore. Ngegesi equkethe ukungcola okuyingozi (isb., H₂S Omkhulu noma olingana no-10 ppm, ama-hydrocarbon asindayo Amakhulu noma alingana no-500 ppm), iyunithi ye-adsorption (ikhabhoni ecushiwe yokukhipha i-sulfurization, izisefo zamangqamuzana okukhipha i-hydrocarbon esindayo) iyengezwa ukuze kuvinjelwe ukuwohloka kwento yolwelwesi kanye nokuncishiswa kokusebenza.
Ukulawula ingcindezi:I-pretreated hydrogen-igesi ecebile iyacindezelwa noma incishiswe kungcindezi yokusebenza yesistimu (0.5-12.0 MPaG) nge-booster compressor noma ivalvu yokwehlisa umfutho. Umehluko wengcindezi ozinzile (imvamisa engu-0.3-10 MPa) phakathi kohlangothi lokuphakelayo (umfutho ophezulu) kanye nohlangothi lwe-permeate (ukucindezela okuphansi) kolwelwesi luyagcinwa ukuze kunikeze amandla okushayela e-hydrogen permeation.
Ukuhlukaniswa kwe-Membrane:I-pressure-gas elawulwayo ingena kumojula ye-membrane (ehlanganiswe izinkulungwane zamafiber membranes angenalutho). Ama-molecule e-hydrogen angena ngokushesha odongeni lwe-membrane aye ohlangothini lwe-permeate ({2}}uhlangothi oluphansi lwengcindezi) ngaphansi komehluko wengcindezi, kuyilapho ukungcola okufana ne-methane, i-carbon dioxide, ne-nitrogen (ukungena okuphansi) kugcinwa ohlangothini lokuphakelayo (uhlangothi olubuyiswayo). Ukuhlanzeka kwe-hydrogen ohlangothini lwe-permeate kufinyelela ku-99.0-99.999% (okushintshwayo ngokulawula indawo ye-membrane kanye nomehluko wengcindezi), futhi izinga lokutholwa kwe-hydrogen-pass eyodwa lingu-70-90%.
Ukuqiniswa kwegesi (i-hydrogen):I-hydrogen ephezulu-emsulwa evela ohlangothini lwe-permeate ingena ethangini le-buffer ukuze izinze ukucindezela (imvamisa engu-0.1-1.0 MPaG). Ezimweni ezidinga ingcindezi ephezulu (isb, ukuthuthwa kwamapayipi, ukusetshenziswa kwamaseli kaphethiloli), i-hydrogen compressor yengezwa ukulungisa ukucindezela ku-2.0-40.0 MPaG. Inani elincane lokungcola okuyinsalela (uma likhona) liphinde lisuswe ngesihlungi sangemuva kwe-adsorption, kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nezidingo zokuhlanzeka komsebenzisi.
Buyisela ukukhishwa kwegesi (ukungcola):Igesi ebuyiselwayo (ukungcola okuphezulu, eno-5-20% eyinsalela H₂) icindezeleka ibe yingcindezi yomoya ngevalvu yokukhulula ingcindezi. Ingasetshenziswa njengophethiloli wamabhayela noma izifudumezi (ukuthola inani le-calorific) noma ikhishwe ngemva kokuhlangabezana nezindinganiso zokukhishwa kwemvelo-igwema imfucumfucu yezinsiza kanye nokungcoliswa kwemvelo.
