Inkqubo yetekhnoloji
Uxinzelelo kunye nokuguqulwa kwegesi yendalo
Igesi yendalo engaphandle komda webhetri iqala icinezelwe ukuya kwi-1.6Mpa yi-compressor, ize ifudunyezwe ukuya kuma-380 ℃ yi-preheater yegesi yokuphakelwa kwindawo yokuhambisa umoya kwisithando somlilo somphunga, ize ingene kwi-desulfurizer ukuze isuse isalfure kwigesi yokuphakelwa engaphantsi kwe-0.1ppm. Igesi yokuphakelwa e-desulfurised kunye nomphunga wenkqubo (3.0mpaa). Lungisa i-preheater yegesi exutyiweyo ngokwexabiso elizenzekelayo le-H2O / ∑ C = 3 ~ 4, ufudumale ngakumbi ukuya ngaphezulu kwe-510 ℃, kwaye ngokulinganayo ungene kwipayipi yokuguqula ukusuka kumbhobho oyintloko wokuqokelela igesi ephezulu kunye nombhobho ophezulu we-pigtail. Kwi-catalyst layer, i-methane isabela kunye nomphunga ukuvelisa i-CO kunye ne-H2. Ubushushu obufunekayo ekuguqulweni kwe-methane bubonelelwa ngumxube wepetroli otshisiweyo kwisitovu esisezantsi. Ubushushu begesi eguquliweyo ephuma kwisithando somlilo somphunga yi-850 ℃, kwaye ubushushu obuphezulu buguqulwa bube kubushushu obuphezulu. Igesi yekhemikhali ingena kwicala letyhubhu yebhoyila yobushushu obumdaka ukuze ivelise umphunga ogcweleyo we-3.0mpaa. Ubushushu begesi yokuguqula ukusuka kwibhoyila yobushushu benkunkuma buyehla bufike kwi-300 ℃, emva koko igesi yokuguqula ingena kwi-preheater yamanzi e-boiler feed, i-conversion gas water cooler kunye ne-conversion gas water separator ukuze yahlule i-condensate kwi-process condensate, kwaye igesi yenkqubo ithunyelwa kwi-PSA.
Igesi yendalo njengepetroli ixutywa negesi yokutsalwa kwe-pressure swing adsorption, kwaye emva koko umthamo wegesi yepetroli kwi-preheater yegesi yepetroli uhlengahlengiswa ngokweqondo lobushushu begesi kwindawo yokuphuma kwesithando sokuguqula. Emva kokulungiswa kokuhamba, igesi yepetroli ingena kwisitshisi esiphezulu ukuze sitshiswe ukuze inike ubushushu kwisithando sokuguqula.
Amanzi acociweyo atshiswa yi-preheater yamanzi acociweyo kunye ne-boiler feed water preheater aze angene kwi-out-product steam ye-flue gas waste boiler kunye ne-reforming gas waste boiler.
Ukuze amanzi okusela kwibhoyila ahlangabezane neemfuno, kufuneka kongezwe isixa esincinci sesisombululo se-phosphate kunye ne-deoxidizer ukuphucula ukukala kunye nokugqwala kwamanzi kwibhoyila. Idrama kufuneka ikhuphe inxalenye yamanzi kwibhoyila rhoqo ukulawula zonke izinto eziqinileyo ezinyibilikisiweyo zamanzi kwibhoyila kwidrama.
Ukutsalwa koxinzelelo lwe-swing
I-PSA ineenqaba ezintlanu zokufunxa. Inqaba enye yokufunxa ikwimeko yokufunxa nangaliphi na ixesha. Izinto ezifana ne-methane, i-carbon dioxide kunye ne-carbon monoxide kwigesi yokuguqula zihlala phezu kwe-adsorbent. I-hydrogen iqokelelwa phezulu kwinqaba yokufunxa njengezinto ezingezizo zokufunxa kwaye ithunyelwa ngaphandle komda. I-adsorbent egcwele izinto ezingcolileyo ikhutshwa kwi-adsorbent ngenyathelo lokuhlaziya. Emva kokuba iqokelelwe, ithunyelwa kwisithando sokuguqula njengefutha. Amanyathelo okuhlaziya enqaba yokufunxa aqulunqwe ngamanyathelo ali-12: ukuhla kokuqala okufanayo, ukuhla kwesibini okufanayo, ukuhla kwesithathu okufanayo, ukukhupha phambili, ukukhupha umva, ukufunxa, ukunyuka kwesithathu okufanayo, ukunyuka kwesibini okufanayo, ukunyuka kokuqala okufanayo kunye nokunyuka kokugqibela. Emva kokuhlaziya, inqaba yokufunxa iyakwazi kwakhona ukunyanga igesi eguquliweyo kunye nokuvelisa i-hydrogen. Iinqaba ezintlanu zokufunxa ziyatshintshana ukwenza la manyathelo angasentla ukuqinisekisa unyango oluqhubekayo. Injongo yokuguqula igesi kunye nokuvelisa i-hydrogen rhoqo ngaxeshanye.
