IiNkcazo zeeMveliso
Inkqubo yokwahlula inwebu ye-hydrogen (ekwabizwa ngokuba yiyunithi yokucoca inwebu ye-hydrogen) yiseti epheleleyo yezixhobo ezidibanisa ukunyangwa kwangaphambili kwegesi, ukwahlula inwebu, kunye nokuzinzisa igesi yemveliso.
Umgaqo wayo ongundoqo kukusebenzisa i-fiber engenanto okanye i-flat -yephepha le-polymer membranes (umzekelo, i-polyimide, i-polysulfone{3}}izinto ezisekelwe) kunye ne-high hydrogen selectivity{4} phantsi koxinzelelo oluthile, iimolekyuli ze-hydrogen (ubunzima beemolekyuli ezincinci, amandla aphezulu e-kinetic) angena kwi-membrane pores ngokukhawuleza kunezinye igesi, i-molecule ye-CO ℂ.
Iyakwazi ukuvelisa i-hydrogen ephezulu -esulungekileyo kwaye sesinye sezona zixhobo ziphambili zokufumana kwakhona i-hydrogen esebenzayo kunye nokucoca kumzi-mveliso we-carbon hydrogen ophantsi{1}.
Umgaqo wokusebenza
Inkqubo yokusebenza ye-Hydrogen yoKwahlula iMembrane inokushwankathelwa njengamanyathelo amahlanu angundoqo: i-hydrogen -igesi etyebileyo yokunyangwa kwangaphambili → ukulawulwa koxinzelelo → ukwahlula inwebu → ukuzinza kwerhasi (i-hydrogen) → ukubuyisela irhasi (ubumdaka)
IHydrogen{0}}etyebileyo ngerhasi yonyango:I-hydrogen -igesi etyebileyo (umzekelo, i-refinery off-irhasi ene-30-}70% ye-H₂, irhasi elungisa igesi yendalo ene-70-90% H₂) ingena kuqala kwinkqubo yonyango lwangaphambili. Idlula kwi-coalescing filter ukususa amaconsi angama-liquid (amanzi, ioli) kunye nobukhulu be-particle Enkulu okanye ilingana ne-1 μm, emva koko ingena kwi-particulate filter ukuphelisa ukungcola okuqinileyo (uthuli, i-catalyst fines) kunye nobukhulu be-particle Enkulu okanye ilingana ne-0.1 μm-ukuphepha ukuvinjelwa kwe-membrane pore. Kwirhasi equlethe ukungcola okuyingozi (umzekelo, i-H₂S Enkulu kune-10 ppm okanye ilingana ne-10 ppm, i-hydrocarbons enzima Enkulu kuno okanye ilingana ne-500 ppm), iyunithi ye-adsorption (i-carbon activated for desulfurization, i-molecular sieves yokususwa kwe-hydrocarbon enzima) yongezwa ukunqanda ukuthotywa kwezinto ze-membrane kunye nokunciphisa ukusebenza.
Ulawulo loxinzelelo:I-hydrogen esetyenzisiweyo{0}}irhasi etyebileyo iyaxinzelelwa okanye ithotywe kuxinzelelo lwenkqubo yokusebenza (0.5-12.0 MPaG) nge-booster compressor okanye ivalve yokunciphisa uxinzelelo. Ukwahlukana koxinzelelo oluzinzile (ngokuqhelekileyo i-0.3-10 MPa) phakathi kwecala lokutya (uxinzelelo oluphezulu) kunye necala le-permeate (uxinzelelo oluphantsi) lwe-membrane lugcinwe ukunika amandla okuqhuba i-hydrogen permeation.
Ukwahlulwa kweMembrane:Uxinzelelo -igesi elawulwayo ingena kwimodyuli ye-membrane (eyenziwe ngamawaka eembrane zefiber ehollow). Iimolekyuli ze-Hydrogen zingena ngokukhawuleza kudonga lwe-membrane ukuya kwicala le-permeate (icala eliphantsi{2}}loxinzelelo) phantsi koxinzelelo, ngelixa ukungcola okufana ne-methane, i-carbon dioxide, kunye ne-nitrogen (i-permeability ephantsi) igcinwa kwicala lokutya (icala lokubuyisela). Ucoceko lwe-hydrogen kwicala le-permeate lufikelela kwi-99.0 - 99.999% (ukulungiswa ngokulawula indawo ye-membrane kunye nokwahlukana koxinzelelo), kunye ne-single-pass hydrogen recovery rate yi-70-90%.
Uzinziso lwerhasi (i-hydrogen):Ihidrojeni ephezulu-esulungekileyo ukusuka kwicala le-permeate ingena kwitanki yesithinteli ukuzinzisa uxinzelelo (ngokwesiqhelo ngu-0.1-1.0 MPaG). Kwiimeko ezifuna uxinzelelo oluphezulu (umzekelo, ukuthuthwa kwemibhobho, ukusetyenziswa kweeseli ze-fuel), i-compressor ye-hydrogen yongezwa ukulungelelanisa uxinzelelo kwi-2.0-40.0 MPaG. Isixa esincinci sokungcola okushiyekileyo (ukuba kukho) kuphinda kususwe nge-post-adsorption filter, ukuqinisekisa ukuba imveliso yokugqibela iyahlangabezana neemfuno zokucoceka komsebenzisi.
Ukukhutshwa kwakhona kwerhasi (ubumdaka):Irhasi ebuyiselwayo (ephezulu kukungcola, kunye ne-5{2}}20% intsalela ye-H₂) icinezelekile kuxinzelelo lwe-atmospheric ngevalve yokukhulula uxinzelelo. Ingasetyenziswa njengezibaso kwizibiyeli okanye kwizifudumezi (ukufumana ixabiso le-calorific) okanye ikhutshwe emva kokuhlangabezana nemigangatho yokukhutshwa kokusingqongileyo-ukuphepha inkunkuma yemithombo kunye nongcoliseko lokusingqongileyo.
