Inkqubo yemveli yokuvelisa igesi yendalo i-hydrogen

Inkqubo yokuveliswa kwe-hydrogen evela kwigesi yendalo ibandakanya iiyunithi ezine: unyango lwegesi yokutya, ukuguqulwa komphunga, ukuguqulwa kwe-CO2 kunye nokucocwa kwe-hydrogen.

(1) Iyunithi yonyango lwegesi yokutya isetyenziselwa kakhulu ukususa i-sulfurization yegesi yendalo, kwaye ii-desulfurizer ze-MnO kunye ne-ZnO zisetyenziselwa ukususa i-H2S kunye ne-SO2. Umthamo wokucubungula wegesi yokutya mkhulu, ngoko ke kukhethwa i-compressor enkulu ye-centrifugal xa kucinezelwa igesi yokutya.

(2) Iyunithi yokuguqula umphunga. Umphunga wamanzi usetyenziswa njenge-oxidant ukuguqula ii-hydrocarbon phantsi kwesenzo se-nickel catalyst ukuze kufunyanwe igesi yokuguqula imveliso ye-hydrogen. Uhlobo kunye nolwakhiwo lwe-reformer zineempawu zazo, kwaye ulwakhiwo, indlela yokuhlawula ubushushu kunye nendlela yokulungisa yabaqokeleli begesi ephezulu nesezantsi nazo zahlukile. Nangona abatshintshi bobushushu kwicandelo le-convection bebekwe ngokwahlukileyo, iiparameter zokusebenza kwenkqubo yokuguqula ubushushu obuphezulu kunye nomlinganiselo wekhabhoni yamanzi ophantsi ziyasetyenziswa kwiyunithi yokuguqula umphunga, nto leyo enceda ekuphuculeni ubunzulu bokuguqula kunye nokonga ukusetyenziswa kwezinto eziluhlaza.

(3) Iyunithi yokuguqula i-CO. Igesi yokutya ethunyelwa kwi-reformer iqulethe inani elithile le-Co. Umsebenzi wokuguqula kukwenza i-co iphendule ngomphunga ukuvelisa i-CO2 kunye ne-H2 xa kukho i-catalyst. Ngokweqondo lobushushu lokuguqula, inkqubo yokuguqula ingahlulwahlulwa ibe yinguquko yobushushu obuphezulu (350 ~ 400 ℃) kunye noguquko lobushushu obuphakathi (ngaphantsi kwe-300 ~ 350 ℃). Kwiminyaka yakutshanje, ngenxa yokugxininisa ekugcinweni kwezixhobo, ukuseta inkqubo yokuguqula yamanqanaba amabini yokuguqulwa kobushushu obuphezulu be-CO kunye nokuguqulwa kobushushu obuphantsi kuye kwamkelwa kwisetingi yenkqubo yeyunithi yokuguqula, ukuze kuncitshiswe ngakumbi ukusetyenziswa kwezinto eziluhlaza.

(4) Iyunithi yokucoca iHydrogen. Kule nkqubo, inkampani nganye yemveliso yeHydrogen isebenzise inkqubo yokucoca nokwahlula i-pressure swing adsorption (PSA) enokusetyenziswa kwamandla aphantsi ukuze ithathe indawo yenkqubo yokucoca nokucoca i-decarbonization kunye nenkqubo yekhemikhali ye-methane enokusetyenziswa kwamandla aphezulu, ukuze kufezekiswe injongo yokonga amandla kunye nokwenza lula inkqubo, kwaye iHydrogen enobumsulwa obufikelela kwi-99.9% inokufumaneka kwindawo yokukhupha iyunithi.
