Umusaruro wa hydrogène by Cracking Ammonia

Amoniya ikoreshwa mu kubyara gaze yamenetse igizwe na azote ya hydrogène ya azote ku kigereranyo cya 3: 1.Imashini isukura gaze ikora amoniya isigaye nubushuhe.Noneho igice cya PSA gikoreshwa mugutandukanya hydrogen na azote nkuko ubishaka.

NH3 iva mu macupa cyangwa mu kigega cya ammonia.Gazi ya amoniya irashyuha mbere yo guhinduranya ubushyuhe na vaporizer hanyuma igacika mubice bikuru.Itanura rishyuha amashanyarazi.

Gutandukanya gaze ya amoniya NH3 ibera ku bushyuhe bwa 800 ° C imbere ya catalizike ishingiye kuri nikel mu itanura rishyushye.
2 NH₃ → N₂ + 3 H₂
Guhindura ubushyuhe bikoreshwa nkubukungu: mugihe gaze ishyushye ikonje, gaze ya amoniya irashyuha.

Nkuburyo bwo guhitamo no kugabanya ikime cyikibyara gaze ikora, hashobora kubaho isuku idasanzwe ya gaz irahari.Ukoresheje tekinoroji ya molekile, ikime cya gaze yakozwe gishobora kugabanuka kugeza kuri 70 ° C.Ibice bibiri bya adsorber bikora murwego rumwe.Imwe ni adsorbing nubushuhe hamwe na ammonia itavunitse kuva gaze ikora mugihe iyindi ishyushye kugirango ivugurure.Imyuka ya gazi ihinduka buri gihe kandi mu buryo bwikora.

Igice cya PSA gikoreshwa mugukuraho azote bityo rero yoza hydrogen, niba bikenewe.Ibi bishingiye kumikorere ifatika ikoresha imiterere itandukanye ya adsorption ya gaze zitandukanye kugirango hydrogène na azote.Mubisanzwe ibitanda byinshi byoherejwe kugirango tumenye ibikorwa bikomeje.

Ubushobozi bwa gaze yameneka: 10 ~ 250 Nm3 / h
Ubushobozi bwa hydrogen: 5 ~ 150 Nm3 / h
