Imveliso yeHydrojeni yi-Ammonia Cracking

I-cracker ye-ammonia isetyenziselwa ukuvelisa igesi eqhekekileyo equka i-nitrogen imbovane ye-hydrogen kwi-mole ratio ye-3:1.I-absorber icoca igesi eyenza i-ammonia eseleyo kunye nokufuma.Emva koko iyunithi yePSA igalelwa ukwahlula ihydrogen kwinitrogen njengokuzikhethela.

I-NH3 iphuma kwiibhotile okanye kwitanki ye-ammonia.Irhasi ye-ammonia ifudunyezwa ngaphambili kwi-heat exchanger kunye ne-vaporizer kwaye emva koko yaqhekeka kwiyunithi yesithando somlilo.Iziko lifudunyezwa ngombane.

Ukuchithwa kwegesi ye-ammonia NH3 kwenzeka kwiqondo lokushisa kwe-800 ° C phambi kwe-nickel-based catalyst kwi-furnace evuthayo yombane.
2 NH₃ → N₂+ 3 H₂
Umtshintshi wokushisa usetyenziswa njenge-economizer: ngelixa i-gas eshushu eqhekezayo ipholile phantsi, igesi ye-ammonia ishushu.

Njengokhetho kwaye ukuze kuncitshiswe indawo yombethe yerhasi eyenziwe ngokwenza ngakumbi, kukho into ekhethekileyo yokwenza i-gas purifier.Ngokusebenzisa iteknoloji yesihluzo semolekyuli, indawo yombethe yerhasi eyenziweyo inokwehliswa ukuya kutsho kuma-70°C.Iiyunithi ezimbini ze-adsorber zisebenza ngokufanayo.Enye ibhengeza ukufuma kunye ne-ammonia engaqhekekanga ukusuka kwirhasi eyenzekileyo ngelixa enye ifudunyezwa ukuze ihlaziywe.Ukuhamba kwegesi kutshintshwa rhoqo kwaye ngokuzenzekelayo.

Iyunithi ye-PSA isetyenziselwa ukususa i-nitrogen kwaye ngoko ke ihlambulule i-hydrogen, ukuba iyafuneka.Oku kusekwe kwinkqubo ebonakalayo eyenza ukusetyenziswa kweempawu ezahlukeneyo ze-adsorption yeegesi ezahlukeneyo ukwahlula i-hydrogen kwinitrogen.Ngokuqhelekileyo iibhedi ezininzi ziye zabekwa ukuze kuqatshelwe umsebenzi oqhubekayo.

Umthamo werhasi yokuqhekeka: 10 ~ 250 Nm3/h
Umthamo weHydrojeni: 5 ~ 150 Nm3/h
