Matsewar iskar gas da juyawa

Gas ɗin da ke waje da iyakar baturi an fara danna shi zuwa 1.6Mpa ta hanyar kwampreso, sa'an nan kuma mai tsanani zuwa kimanin 380 ℃ ta hanyar iskar gas preheater a cikin sashin convection na tanderun mai gyara tururi, kuma ya shiga desulfurizer don cire sulfur a cikin iskar gas. kasa 0.1ppm. The desulfurized feed gas da aiwatar tururi (3.0mpaa) Daidaita gauraye gas preheater bisa ga atomatik darajar H2O / ∑ C = 3 ~ 4, kara preheat zuwa fiye da 510 ℃, da kuma ko'ina shigar da tuba bututu daga babba gas taro. babban bututu da babba pigtail bututu. A cikin mai kara kuzari, methane yana amsawa da tururi don samar da CO da H2. Ana ba da zafi da ake buƙata don canjin methane ta hanyar cakuda man da aka ƙone a ƙasa mai ƙonewa. Yanayin zafin gas ɗin da aka canza daga tanderun gyara shine 850 ℃, kuma babban zafin jiki yana canzawa zuwa babban zafin jiki. Gas ɗin sinadarai yana shiga gefen bututu na tukunyar zafi mai sharar gida don samar da 3.0mpaa cikakken tururi. Zazzabi na iskar gas mai jujjuyawa daga tukunyar ruwa mai sharar gida ya faɗi zuwa 300 ℃, sannan iskar gas ɗin juyawa ta shiga cikin tukunyar tukunyar tukunyar tukunyar jirgi, mai sanyaya ruwan iskar gas da mai raba ruwan iskar gas a bi da bi don raba condensate daga tsarin condensate, da Ana aika iskar gas zuwa PSA.
The halitta gas a matsayin man fetur ne gauraye da matsa lamba lilo adsorption desorption gas, sa'an nan kuma man fetur ƙarar gas a cikin man fetur preheater aka gyara bisa ga gas zafin jiki a kanti na reformer tanderu. Bayan daidaita magudanar ruwa, iskar gas ɗin tana shiga saman mai ƙonewa don konewa don samar da zafi ga tanderun gyara.
Ruwan da aka ƙera ana preheated da na'urar busar da ruwa da tukunyar jirgi mai ciyar da ruwa da kuma shigar da tururi ta hanyar tururi na bututun iskar gas da kuma gyara tukunyar sharar iskar gas.
Domin samar da ruwan dafa abinci na tukunyar jirgi ya dace da buƙatun, za a ƙara ƙaramin adadin phosphate da deoxidizer don inganta haɓakawa da lalata ruwan tukunyar jirgi. Ganga za ta ci gaba da fitar da wani yanki na ruwan tukunyar jirgi don sarrafa jimillar narkar da daskarar ruwan tukunyar a cikin ganga.

Adsorption na matsa lamba

PSA ta ƙunshi hasumiya masu tallatawa guda biyar. Hasumiyar talla ɗaya tana cikin yanayin talla a kowane lokaci. Abubuwan da aka haɗa kamar methane, carbon dioxide da carbon monoxide a cikin iskar gas ɗin da ke juyawa suna tsayawa a saman adsorbent. Ana tattara hydrogen daga saman hasumiya ta talla a matsayin abubuwan da ba a haɗa su ba kuma ana aika su daga kan iyaka. Adsorbent cike da abubuwan ƙazanta ana lalata shi daga adsorbent ta hanyar sabuntawa. Bayan an tattara, sai a aika zuwa tanderun gyara a matsayin mai. Matakan sabuntawa na hasumiya ta adsorption sun ƙunshi matakai 12: digo na farko na uniform, digo na biyu, digo na uku, fitarwa na gaba, juyewar juyewa, tashiwar yunifom na uku, tashi yunifom na biyu, tashin riga na farko da tashin ƙarshe. Bayan sabuntawa, hasumiya ta adsorption ta sake samun damar yin maganin gas ɗin da aka canza da kuma samar da hydrogen. Hasumiya mai ɗaukar hoto guda biyar suna ɗaukar bi da bi don aiwatar da matakan da ke sama don tabbatar da ci gaba da jiyya. Manufar canza gas da ci gaba da samar da hydrogen a lokaci guda.

Iyakar baturi Division

Gas ɗin da ke waje da iyakar baturi yana shiga naúrar ta bututun, kuma ana fitar da samfurin hydrogen zuwa naúrar ta bututun. Bangaren da ke kewaye da layin dige-dige a cikin wannan adadi shine iyakar baturi na naúrar.

Ciyar da iskar gas tana shiga cikin naúrar daga aya ① a cikin hoton da ke ƙasa, ana fitar da hydrogen samfurin daga aya ② a cikin adadi, kuma iskar gas yana fitowa daga aya ③ a cikin adadi.
