Tsarin samar da hydrogen na iskar gas ya ƙunshi matakai huɗu: pretreatment iskar gas, canjin tururi na iskar gas, canjin carbon monoxide da tsarkakewar hydrogen.
Mataki na farko shine pretreatment na albarkatun kasa. Pretreatment a nan yafi nufin desulfurization na danyen gas. A cikin ainihin aiki na tsari, ana amfani da iskar gas cobalt molybdenum hydrogenation jerin zinc oxide gabaɗaya azaman desulfurizer don canza sulfur na halitta a cikin iskar gas zuwa sulfur na inorganic sannan a cire shi. Ruwan ɗanyen iskar gas ɗin da aka yi amfani da shi a nan yana da girma, don haka ana iya amfani da tushen iskar gas tare da matsa lamba mai yawa ko kuma ana iya yin la'akari da babban gefe yayin zabar na'ura mai sarrafa iskar gas.
Mataki na biyu shine juyar da tururi na iskar gas. Ana amfani da sinadarin nickel a cikin mai gyara don canza alkanes a cikin iskar gas zuwa iskar gas mai abinci tare da manyan abubuwan haɗin carbon monoxide da hydrogen.
Sa'an nan kuma, carbon monoxide yana jujjuya don amsawa da tururin ruwa a gaban mai kara kuzari don samar da hydrogen da carbon dioxide don samun iskar gas mai jujjuyawa wanda manyan abubuwan da suka hada da hydrogen da carbon dioxide. Dangane da yanayin juzu'i daban-daban, tsarin jujjuyawar carbon monoxide za a iya raba shi zuwa nau'i biyu: matsakaicin zafin jiki da canjin yanayin zafi. A high zafin jiki hira zafin jiki ne game da 360 ℃, da kuma matsakaici zafin jiki hira tsari ne game da 320 ℃. Tare da ci gaban fasaha countermeasures, da mataki biyu tsari saitin na carbon monoxide high-zazzabi hira da low-zazzabi hira da aka soma a cikin 'yan shekarun nan, wanda zai iya kara ceton amfani da albarkatun. Duk da haka, don yanayin cewa abun ciki na carbon monoxide a cikin iskar gas ɗin ba ta da girma, za a iya ɗaukar matsakaicin zafin jiki kawai.
Mataki na ƙarshe shine tsarkake hydrogen. Yanzu tsarin tsarkakewar hydrogen da aka fi amfani dashi shine tsarin PAS, wanda kuma aka sani da tsarin tsarkakewa da rabuwar PSA. Wannan tsarin yana da ƙarancin amfani da makamashi, tsari mai sauƙi da babban tsabta na samar da hydrogen. A mafi girma, tsarkin hydrogen zai iya kaiwa 99.99%.
