Ukukhiqizwa kwe-Hydrogen ngu-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 ishisiswe ngaphambilini 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.Eyodwa ifaka umswakama kanye ne-ammonia engaqhekeziwe ephuma egesini eyakhayo kuyilapho enye ifudunyezwa ukuze ivuselelwe.Ukugeleza kwegesi kushintsha njalo futhi ngokuzenzakalelayo.

Iyunithi ye-PSA isetshenziselwa ukususa i-nitrogen ngakho-ke ihlanza i-hydrogen, uma idingeka.Lokhu kusekelwe enqubweni ebonakalayo esebenzisa izici ezihlukene zokukhangisa zamagesi ahlukene ukuhlukanisa i-hydrogen ku-nitrogen.Ngokujwayelekile imibhede eminingana isetshenziswa ukuze kuqashwe ukusebenza okuqhubekayo.

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