Kupanga Hydrogen ndi Ammonia Cracking

Chophwanyira cha ammonia chimagwiritsidwa ntchito popanga mpweya wosweka womwe umapangidwa ndi hydrogen ant nitrogen pa mole ya 3: 1.Chotsitsacho chimatsuka mpweya wopangidwa kuchokera ku ammonia ndi chinyezi.Kenako gawo la PSA limayikidwa kuti lilekanitse haidrojeni ku nayitrogeni ngati mukufuna.

NH3 imachokera m'mabotolo kapena kuchokera ku thanki ya ammonia.Mpweya wa ammonia umatenthedwa kale mu chotenthetsera kutentha ndi vaporizer kenako ndikusweka mu ng'anjo yayikulu.Ng'anjoyo imatenthedwa ndi magetsi.

Kusokonezeka kwa mpweya wa ammonia NH3 kumachitika pa kutentha kwa 800 ° C pamaso pa chothandizira chopangidwa ndi nickel mu ng'anjo yotentha yamagetsi.
2 NH₃ → N₂+ 3 H₂
Kutentha kwa kutentha kumagwiritsidwa ntchito ngati chuma: pamene mpweya wotentha wotentha umatsitsidwa, mpweya wa ammonia umatenthedwa.

Monga njira komanso kuti muchepetse mame a gasi wopangidwa mopitilira, choyeretsa chapadera chopangira gasi chilipo.Pogwiritsa ntchito ukadaulo wa masieve a molekyulu, mame a mpweya wopangidwa amatha kuchepetsedwa mpaka -70 ° C.Magawo awiri a adsorber akugwira ntchito limodzi.Imodzi imatulutsa chinyezi komanso ammonia osasweka kuchokera ku gasi wopangidwa pomwe ina imatenthedwa kuti ipangidwenso.Kutuluka kwa gasi kumasinthidwa pafupipafupi komanso zokha.

Chigawo cha PSA chimagwiritsidwa ntchito kuchotsa nayitrogeni motero kuyeretsa haidrojeni, ngati pakufunika.Izi zimatengera momwe thupi limagwirira ntchito zomwe zimagwiritsa ntchito ma adsorption osiyanasiyana amitundu yosiyanasiyana kuti alekanitse haidrojeni ku nayitrogeni.Nthawi zambiri mabedi angapo amayikidwa kuti akwaniritse ntchitoyo.

Kutha kwa gasi: 10 ~ 250 Nm3 / h
Mphamvu ya haidrojeni: 5 ~ 150 Nm3/h
