Iyunithi yokukhiqiza i-hydrogen ye-Rongteng yegesi yemvelo

Isingeniso

Inqubo yokukhiqiza i-hydrogen yegesi yemvelo ikakhulukazi ihlanganisa izinqubo ezine: igesi yokuphakelayo kusengaphambili, ukuguqulwa kwesitimu segesi yemvelo, ukuguqulwa kwe-carbon monoxide kanye nokuhlanzwa kwe-hydrogen.

Isinyathelo sokuqala ukwelashwa kwempahla eluhlaza . Ukwelashwa kuqala lapha ikakhulukazi kubhekisela ekususweni kwegesi eluhlaza. Emsebenzini wangempela wenqubo, igesi yemvelo ye-cobalt molybdenum hydrogenation series zinc oxide ngokuvamile isetshenziswa njenge-desulfurizer ukuguqula isibabule esiphilayo esisegesini yemvelo sibe isibabule esingaphili bese siyasisusa. Ukugeleza kwegesi yemvelo eluhlaza ephathwa lapha kukhulu, ngakho umthombo wegesi yemvelo onomfutho ophezulu ungasetshenziswa noma umkhawulo omkhulu ungacatshangelwa lapho kukhethwa i-compressor yegesi yemvelo.

Isinyathelo sesibili ukuguqulwa kwesitimu segesi yemvelo. I-nickel catalyst isetshenziswa kunguquko ukuguqula ama-alkanes kugesi yemvelo abe igesi yokuphakelayo enezingxenye eziyinhloko ze-carbon monoxide ne-hydrogen.

Khona-ke, i-carbon monoxide iyaguqulwa ukuze isabele ngomhwamuko wamanzi phambi kwe-catalyst ukukhiqiza i-hydrogen ne-carbon dioxide ukuze kutholwe igesi yokuguqula izingxenye zayo eziyinhloko kuyi-hydrogen ne-carbon dioxide. Ngokwezinga lokushisa elihlukile lokuguqulwa, inqubo yokuguqulwa kwe-carbon monoxide ingahlukaniswa ibe izinhlobo ezimbili: ukuguqulwa kwezinga lokushisa eliphakathi nokuguqulwa kokushisa okuphezulu. Izinga lokushisa eliphezulu lokuguqulwa kwezinga lokushisa licishe libe ngu-360 ℃, futhi inqubo yokuguqula izinga lokushisa eliphakathi licishe libe ngu-320 ℃. Ngokuthuthukiswa kwezinyathelo eziphikisanayo zobuchwepheshe, ukumiswa kwenqubo yezigaba ezimbili ze-carbon monoxide yokuguqulwa kwezinga lokushisa eliphezulu kanye nokuguqulwa kwezinga lokushisa eliphansi kuye kwamukelwe ngo. eminyakeni yamuva, okungase kuqhubeke ukonga ukusetshenziswa kwezinsiza. Kodwa-ke, esimweni sokuthi okuqukethwe kwe-carbon monoxide kugesi yokuguqulwa akuphakeme, ukuguqulwa kwezinga lokushisa okuphakathi kuphela kungamukelwa.

Isinyathelo sokugcina ukuhlanza i-hydrogen. Manje uhlelo lokuhlanzwa kwe-hydrogen olusetshenziswa kakhulu uhlelo lwe-PAS, olwaziwa nangokuthi uhlelo lokuhlanzwa kwe-PSA nokuhlukanisa. Lolu hlelo lunokusetshenziswa kwamandla okuphansi, inqubo elula kanye nokuhlanzeka okuphezulu kokukhiqizwa kwe-hydrogen. Phezulu, ubumsulwa be-hydrogen bungafinyelela ku-99.99%.

Imishini yenqubo eyinhloko
