Ngemuva kwe-hydrogen (H2) igesi exubile ingena kuyunithi ye-press swing adsorption (PSA), ukungcola okuhlukahlukene kwigesi ephakelayo kukhangiswa ngokuzikhethela embhedeni ngama-adsorbents ahlukahlukene kumbhoshongo we-adsorption, futhi ingxenye engakhangi, i-hydrogen, ithunyelwa isuka lapho kuphuma khona i-adsorption. umbhoshongo. Ngemuva kokuthi i-adsorption isigcwele, ukungcola kuyasuswa futhi i-adsorbent ivuselelwe.

Izici ze-PSA Hydrogen Plant
I-TCWY PSA hydrogen purification plant inohlu lwezici ezihlaba umxhwele eziyenza ibe ukukhetha okuphezulu ekukhiqizweni kwe-hydrogen ezindaweni ezihlukahlukene zezimboni. Igqama ngokwenza ngendlela oyifisayo umzila wayo wenqubo ukuze uqondaniswe ngokunembile nezidingo ezithile zemboni ngayinye, iqinisekisa hhayi kuphela isivuno esikhulu segesi kodwa futhi nekhwalithi yomkhiqizo ezinzile njalo.
Enye yamandla ayo ayisisekelo asekusetshenzisweni kwayo kwama-adsorbent asebenza kahle kakhulu abonisa ukukhetha okukhethekile kokungcola, ngaleyo ndlela iqinisekisa ukusebenza okuthembekile nokuhlala njalo okunesikhathi sokuphila esingaphezu kweminyaka eyi-10. Ngaphezu kwalokho, lesi sitshalo sihlanganisa ama-valve okulawula ahlelekayo aklanyelwe ukuphila isikhathi eside, nesikhathi sokuphila esingaphezu kweminyaka eyishumi. Lawa ma-valve angenziwa ngendlela efanele ukuze asebenze kusetshenziswa umfutho kawoyela noma izindlela zomoya, okuthuthukisa ukuguquguquka nokuvumelana nezimo.
I-TCWY PSA Hydrogen Plant inohlelo lokulawula olungenasici oluvumelana ngaphandle komthungo nokuhlelwa okuhlukahlukene kokulawula, okulwenza lube yisixazululo esisebenza ngezindlela eziningi nesinokwethenjelwa sezidingo zezimboni ezihlukahlukene. Kungakhathaliseki ukuthi ukusebenza okuqinile, ukuphila okunwetshiwe, noma ukuzivumelanisa nezimo kumasistimu okulawula ahlukahlukene, lesi sitshalo se-hydrogen sihamba phambili kuzo zonke izinhlangothi.
(1) Inqubo ye-PSA-H2 Yokukhangiswa Kwezitshalo
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) PSA-H2 Plant Equal Depressurization
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) PSA-H2 Plant Pathwise Pressure Release
Ngemva kwenqubo elinganayo yokucindezeleka, eduze nokuqondisa kwe-adsorption umkhiqizo H2 phezu 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) I-PSA-H2 Plant Reverse Depressurization
Ngemuva kwenqubo yokukhishwa kwengcindezi ehamba phambili, indawo ye-adsorption eya phambili isifinyelele ekuphumeni kwesendlalelo sombhede. 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) I-PSA-H2 Ukuhlanzwa Kwezitshalo
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) PSA-H2 Plant 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) Ukucindezelwa Kokugcina Kwegesi Yomkhiqizo Wezitshalo ze-PSA-H2
Ngemuva kwezinqubo zokucindezela ezilinganayo izikhathi eziningana, ukuze ushintshele umbhoshongo we-adsorption isinyathelo esilandelayo sokukhangisa kancane kancane futhi uqinisekise ubumsulwa bomkhiqizo abuguquguquki, idinga ukusebenzisa umkhiqizo H2 nge-boost control valve ukuphakamisa ukucindezela kombhoshongo we-adsorption kungcindezi ye-adsorption. kancane futhi kancane.
Ngemuva kwenqubo, imibhoshongo ye-adsorption iqedela wonke umjikelezo "wokuvuselela i-adsorption", futhi yenza amalungiselelo okukhangisa okulandelayo.
