Tlhahiso ea Hydrogen ka Ammonia Cracking

Sekoahelo sa ammonia se sebelisoa ho hlahisa khase e petsohang e entsoeng ka hydrogen ant nitrogen ka molek'hule ea 3:1.Mokelikeli o hloekisa khase e entsoeng ho tloha ho ammonia le mongobo o setseng.Ebe yuniti ea PSA e sebelisoa ho arola haedrojene ho nitrogen joalo ka boikhethelo.

NH3 e tsoa libotlolong kapa tanka ea ammonia.Khase ea ammonia e futhumatsoa pele ho mochini oa mocheso le mouoane ebe e phunyeha ka har'a yuniti e kholo ea sebōpi.Sebōpi se hotetsoa ka motlakase.

Ho arohana ha khase ea ammonia NH3 ho etsahala ka mocheso oa 800 ° C ka pel'a mokelikeli o thehiloeng ho nickel ka sebōping se futhumetseng sa motlakase.
2 NH₃ → N₂+ 3 H₂
Mocheso oa mocheso o sebelisoa e le moruo: ha khase e chesang e chesang e pholile, khase ea ammonia e chesoa pele.

E le khetho, 'me e le ho fokotsa phoka ea khase e entsoeng ka khase, ho na le mochine o khethehileng oa ho etsa khase.Ka ho sebelisa theknoloji ea sieve ea limolek'hule, ntlha ea phoka ea khase e hlahisoang e ka fokotsoa ho -70°C.Likarolo tse peli tsa adsorber li sebetsa ka ho tšoana.E 'ngoe ke mongobo o khahlehang le ammonia e sa phunyehang ho tloha khase e entsoeng ha e' ngoe e futhumatsoa bakeng sa ho nchafatsoa.Phallo ea khase e fetoloa khafetsa le ka bo eona.

Setsi sa PSA se sebelisetsoa ho tlosa naetrojene ka hona ho hloekisa hydrogen, haeba ho hlokahala.Sena se ipapisitse le ts'ebetso ea 'mele e sebelisang lisebelisoa tse fapaneng tsa adsorption ea likhase tse fapaneng ho arola hydrogen ho naetrojene.Hangata libethe tse 'maloa li sebelisoa ho hlokomela ts'ebetso e tsoelang pele.

Bokhoni ba khase e phunyehang: 10 ~ 250 Nm3/h
Matla a haedrojene: 5 ~ 150 Nm3/h
