Ukukhiqizwa kweHydrojeni yi-Amonia Cracking

I-ammonia cracker isetshenziselwa ukukhiqiza igesi eqhekekayo ehlanganisa i-hydrogen ant nitrogen nge-mole ratio engu-3:1. I-absorber ihlanza igesi eyenza i-ammonia esele kanye nomswakama. Bese kusetshenziswa iyunithi ye-PSA ukuhlukanisa i-hydrogen ku-nitrogen njengokuzikhethela.

I-NH3 iphuma emabhodleleni noma ethangini le-ammonia. Igesi ye-ammonia ishiswa ngaphambili kusishintshi sokushisa kanye ne-vaporizer bese iqhekeka kuyunithi yesithando somlilo esikhulu. Isithando somlilo sishisisa ngogesi.

Ukuhlukaniswa kwegesi ye-ammonia NH3 kwenzeka ekushiseni kuka-800 ° C phambi kwe-catalyst esekelwe ku-nickel esithandweni somlilo esishiswa ngogesi.
2 NH₃ → N₂+ 3 H₂
Umshini wokushisa usetshenziswa njenge-economizer: ngenkathi igesi eshisayo eqhekekayo ipholile, igesi ye-ammonia ishisa ngaphambili.

Njengenketho futhi ukuze kuncishiswe iphuzu lamazolo egesi eyakhayo eyakhiwe ngokuqhubekayo, isicoci segesi esikhethekile sokwenza igesi siyatholakala. Ngokusebenzisa ubuchwepheshe be-molecular sieve, indawo yamazolo yegesi ekhiqizwayo ingancishiswa ibe -70°C. Amayunithi e-adsorber amabili asebenza ngokufana. Omunye ukhangisa umswakama kanye ne-ammonia engaqhekeziwe esuka egesini eyakhayo kuyilapho enye ishiselwa ukuze ivuselelwe. Ukugeleza kwegesi kushintsha njalo futhi ngokuzenzakalelayo.

Iyunithi ye-PSA isetshenziselwa ukususa i-nitrogen futhi ngenxa yalokho ihlanze i-hydrogen, uma idingeka. Lokhu kusekelwe enqubweni ebonakalayo esebenzisa izici ezihlukene zokukhangisa zamagesi ahlukene ukuhlukanisa i-hydrogen ku-nitrogen. Ngokuvamile imibhede eminingana isetshenziswa ukuze kuqaliswe ukusebenza okuqhubekayo.

Umthamo wegesi yokuqhekeka: 10 ~ 250 Nm3/h
Umthamo we-hydrogen: 5 ~ 150 Nm3/h
