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 ivela 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
