Isicelo
Ukuphinda usebenzise i-H2kusuka ku-H2-ingxube yegesi ecebile efana negesi eshintshwayo, igesi ecwengisisiwe, igesi ephakathi kwamanzi, igesi yedolobha, igesi ye-coke-oven, igesi yokuvutshelwa, igesi yomsila we-methanol, igesi yomsila we-formaldehyde, igesi eyomile ye-FCC yokuhluza uwoyela, igesi yomsila weshift neminye imithombo yegesi no-H2.
Izici
1. I-TCWY izinikele ekuklameni nasekwakheni i-Pressure Swing Adsorption Plant ebizayo esebenza kahle.Ngokusho kwezidingo eziqondile zamakhasimende kanye nezici zokukhiqiza, uhlelo lobuchwepheshe olufanele kakhulu, umzila wenqubo, izinhlobo ze-adsorbents kanye nesilinganiso kunikezwa ukuze kuqinisekiswe isivuno segesi ephumelelayo kanye nokuthembeka kwenkomba.
2. Ohlelweni lokusebenza, iphakheji yesofthiwe yokulawula evuthiwe nethuthukisiwe iyamukelwa ukuze kulungiselelwe isikhathi sokukhangisa, esivumela isitshalo ukuthi sisebenze ngemodi yokonga kakhulu isikhathi eside futhi sikhululeke ethonyeni lezinga lobuchwepheshe nokusebenza ngokunganaki kwabaqhubi. .
3. Ubuchwepheshe bokugcwalisa okuminyene be-adsorbents bamukelwa ukuze kuqhutshekwe nokunciphisa izikhala ezifile phakathi kwezingqimba zombhede nokwandisa izinga lokubuyisela izingxenye ezisebenzayo.
4. Ukuphila kwamavalvu ethu ahlelekayo e-PSA anobuchwepheshe obukhethekile kungaphezu kwezikhathi eziyisigidi.
(1) Inqubo Ye-Adsorption
I-Feed Gas ingena embhoshongweni we-adsorption kusukela phansi kombhoshongo (Owodwa noma ambalwa ahlala esesimweni sokukhangisa).Ngokufakwa okukhethiwe kwama-adsorbent ahlukahlukene ngokulandelana, ukungcola kuyakhangiswa futhi i-H2 engena-adsorbed iphuma phezulu kombhoshongo.
Lapho indawo yokuya phambili yendawo yokudlulisa inqwaba (indawo ye-adsorption phambili) yokungcola kwe-adsorption ifinyelela engxenyeni yokuphuma egodliwe yesendlalelo sombhede, vala i-valve yokuphakelayo yegesi ephakelayo kanye ne-valve yokuphuma yegesi yomkhiqizo, misa ukukhangiswa.Bese umbhede we-adsorbent ushintshelwa kunqubo yokuvuselela.
(2) Ukucindezeleka Okulinganayo
Ngemuva kwenqubo ye-adsorption, eduze nendawo ye-adsorption faka i-high-pressure H2 kumbhoshongo we-adsorption kwenye umbhoshongo ophansi we-adsorption oqede ukukhiqizwa kabusha.Yonke inqubo akuyona nje inqubo yokucindezeleka, kodwa futhi inqubo yokubuyisela i-H2 yendawo efile yombhede.Inqubo ihlanganisa izikhathi ezimbalwa ekusakazeni ukucindezeleka okulinganayo, ukuze ukutakula kwe-H2 kungaqinisekiswa ngokugcwele.
(3) Ukukhishwa Kwengcindezi Okuhamba Phambili
Ngemva kwenqubo elinganayo yokucindezeleka, eduze kwendlela yokukhangisa umkhiqizo H2 ongaphezulu kombhoshongo we-adsorption ubuyiselwa ngokushesha ku-pathwise pressure release gas buffer tank (PP Gas Buffer Tank), le ngxenye ye-H2 izosetshenziswa njengomthombo wegesi wokuvuselela we-adsorbent. ukucindezeleka.
(4)Reverse Depressurization
Ngemuva kwenqubo yokukhishwa kwengcindezi elandelanayo, indawo yokuya phambili ye-adsorption ifinyelele ekuphumeni kombhede.Ngalesi sikhathi, ukucindezelwa kombhoshongo we-adsorption kuncishisiwe ku-0.03 barg noma ngaphezulu ekuqondeni okungalungile kwe-adsorption, inani elikhulu lokungcola okukhangisiwe liqala ukukhishwa ku-adsorbent.I-reverse depressurization gas desorbed ingena ethangini le-buffer gas buffer bese ixubana negesi yokuhlanza kabusha.
(5) Ukuhlanza
Ngemuva kwenqubo yokuhlehla yokucindezeleka, ukuze uthole ukuvuselelwa okuphelele kwe-adsorbent, sebenzisa i-hydrogen ye-pathwise pressure release release gas buffer tank ohlangothini olubi lwe-adsorption ukuze ugeze isendlalelo sombhede we-adsorption, unciphise nakakhulu ingcindezi ye-fractional, futhi i-adsorbent ingaba ngokuphelele. ivuselelwe, le nqubo kufanele ihambe kancane futhi izinzile ukuze umphumela omuhle wokuvuselela uqiniseke.Ukuhlanza igesi yokuvuselela kabusha kuphinde kufake ithangi le-blowdown tail buffer buffer.Ngemuva kwalokho izothunyelwa ngaphandle komkhawulo webhethri futhi isetshenziswe njengegesi yamafutha.
(6)I-Equal Repressurization
Ngemuva kokuhlanza inqubo yokuvuselela kabusha, sebenzisa i-H2 ephezulu yokucindezela ukusuka komunye umbhoshongo we-adsorption ukuze ucindezele kabusha umbhoshongo we-adsorption ngokuphindaphindiwe, le nqubo ihambisana nenqubo ye-depressurization elinganayo, akuyona nje inqubo yokukhulisa ingcindezi, kodwa futhi inqubo yokubuyisela i-H2 endaweni efile yombhede yomunye umbhoshongo we-adsorption.Inqubo ihlanganisa izikhathi ezimbalwa ekusakazweni kwezinqubo zokucindezela okulinganayo.
(7)I-Product Gas Final Repressurization
Ngemuva kwezinqubo zokucindezela ezilinganayo izikhathi eziningana, ukuze uguqule umbhoshongo we-adsorption uye esinyathelweni esilandelayo sokukhangisa kancane kancane futhi uqinisekise ubumsulwa bomkhiqizo abuguquguquki, idinga ukusebenzisa umkhiqizo H2 nge-boost control valve ukuphakamisa ingcindezi yombhoshongo we-adsorption kungcindezi ye-adsorption. kancane futhi kancane.
Ngemva kwenqubo, imibhoshongo ye-adsorption iqedela wonke umjikelezo "wokuvuselela i-adsorption", futhi yenza amalungiselelo okukhangisa okulandelayo.
