Malo opangira ma hydrogen a Rongteng pamagesi achilengedwe

Mawu Oyamba

Njira yopangira haidrojeni ya gasi wachilengedwe imaphatikizapo njira zinayi: kuperekera mpweya wamafuta, kutembenuza nthunzi ya gasi, kutembenuza mpweya wa carbon monoxide ndi kuyeretsa hydrogen.

Gawo loyamba ndi pretreatment zopangira . The pretreatment apa makamaka amatanthauza desulfurization ya mpweya waiwisi. Mu ntchito yeniyeni ndondomeko, gasi zachilengedwe cobalt molybdenum hydrogenation mndandanda nthaka okusayidi zambiri ntchito monga desulfurizer kutembenuza organic sulfure mu gasi mu zosawerengeka sulfure ndiyeno kuchotsa izo. Kuthamanga kwa gasi wakuda wopangidwa pano ndi kwakukulu, kotero kuti gwero la gasi lachilengedwe lomwe lili ndi mphamvu zambiri lingagwiritsidwe ntchito kapena malire aakulu angagwiritsidwe ntchito posankha kompresa ya gasi.

Gawo lachiwiri ndi kusintha kwa nthunzi kwa gasi. Chothandizira cha Nickel chimagwiritsidwa ntchito pokonzanso kusintha ma alkanes mu gasi wachilengedwe kukhala mpweya wamafuta okhala ndi zigawo zazikulu za carbon monoxide ndi hydrogen.

Kenaka, carbon monoxide imasinthidwa kuti igwirizane ndi mpweya wa madzi pamaso pa chothandizira kuti apange haidrojeni ndi carbon dioxide kuti apeze mpweya wosinthika womwe zigawo zake zazikulu ndi hydrogen ndi carbon dioxide. Malinga ndi kutentha kosiyana kutembenuka, kutembenuka kwa mpweya monoxide akhoza kugawidwa mu mitundu iwiri: sing'anga kutentha kutembenuka ndi mkulu kutentha kutembenuka. Kutentha kwapamwamba kwambiri kwa kutentha kumakhala pafupifupi 360 ℃, ndipo njira yosinthira kutentha kwa sing'anga ndi pafupifupi 320 ℃. Ndi chitukuko cha zipangizo zamakono, kusinthika kwa magawo awiri a carbon monoxide high-temperature ndi kutembenuka kwapansi kwakhala kuvomerezedwa mu zaka zaposachedwa, zomwe zitha kupulumutsanso kugwiritsa ntchito zinthu. Komabe, chifukwa chakuti carbon monoxide zili mu kutembenuka mpweya si mkulu, kokha sing'anga kutentha kutembenuka akhoza anatengera.

Gawo lomaliza ndikuyeretsa haidrojeni. Tsopano njira yomwe imagwiritsidwa ntchito kwambiri pakuyeretsa hydrogen ndi PAS system, yomwe imadziwikanso kuti PSA kuyeretsa ndi kupatukana. Dongosololi lili ndi mphamvu zochepa zogwiritsa ntchito mphamvu, njira yosavuta komanso yoyera kwambiri yopanga ma hydrogen. Pamwamba kwambiri, kuyera kwa haidrojeni kumatha kufika 99.99%.
