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:
1. Ukukhetha umzila wenqubo onengqondo kakhulu ngokwezimo zangempela zamafekthri, onesivuno esikhulu segesi kanye nekhwalithi yomkhiqizo ezinzile.
2. I-adsorbent esebenza kahle kakhulu inokukhangiswa okuqinile kokungcola, i-adsorbent enamandla nempilo ende engaphezu kweminyaka eyi-10.
3. Ukulungiswa kwama-valve okulawula ahlelekayo akhethekile, ubude besikhathi se-valve bungaphezu kweminyaka eyi-10, ifomu lokushayela lingahlangabezana nokucindezela kawoyela noma i-pneumatic.
4. Inesistimu yokulawula ephelele futhi ifanele zonke izinhlobo zezinhlelo zokulawula.
PSA hydrogen plantigesi yokudla esebenzayo: Igesi yokuqhekeka ye-Methanol, igesi eqhekezayo ye-ammonia, igesi ye-methanol yomsila kanye negesi yomsila ye-formaldehyde Igesi yokwenziwa, i-shift gas, igesi yokucwenga, igesi ye-hydrocarbon steam reforming, igesi yokuvutshelwa, i-polycrystalline silicon tail gas I-semi-water gas, igesi yedolobha, i-coke oven igesi kanye ne-orchid tail gas Refinery I-FCC igesi eyomile kanye ne-refinery reforming tail gas Eminye Imithombo Yegesi Equkethwe
Ukuhlanzeka kwe-H2: 98%~99.999%
I-PSA Technology nayo ingasetshenziswa ku:
1. Ukuhlukaniswa kwe-CO2 nokuhlanzwa (PSA - CO2)
Ukugaywa kabusha kwe-CO2 kugaywa kabusha kusuka kungxube yegesi enothe nge-CO2. Amagesi wezinto ezibonakalayo ahlanganisa: njengegesi ephumayo ye-lime kiln, igesi yokuvutshelwa, igesi eguquliwe, igesi yezimayini yemvelo kanye neminye imithombo yegesi ene-CO2. Ukuhlanzeka kokufinyelela kwe-CO2 kabusha kungafinyelela ku-98~99.99%.
2. I-CO Separation and Purification (PSA - CO)
Ukugaywa kabusha kwe-CO ehlanzekile kugaywa kabusha kusuka kungxube ye-CO-rich gas. Amagesi wezinto ezibonakalayo ahlanganisa: njengegesi ephakathi kwamanzi, igesi yamanzi, igesi ye-blast furnace ye-cuprammonia evuselelwe kabusha, igesi ephuzi ye-phosphorus yomsila kanye neminye imithombo yegesi ene-CO. Ukuhlanzeka kwe-CO egaywe kabusha kungafinyelela ubumsulwa be-CO efinyelela ku-80~99.9% .
3. Ukususwa kwe-CO2 (I-PSA - Ukususwa kwe-CO2)
Khipha i-CO2 kugesi eguquliwe, esetshenziselwa ukukhipha ikhabhoni yokwenziwa kwe-ammonia nokukhiqizwa kwe-methanol.
