Tailored Hydrogen tsim cov nroj tsuag los ntawm natural gas

Taw qhia

Hydrogen ntau lawm los ntawm natural gas muaj qhov zoo ntawm tus nqi qis thiab cov txiaj ntsig tseem ceeb. Kev tshawb fawb thiab kev loj hlob ntawm cov txheej txheem tshiab tshiab tshaj plaws rau hydrogen ntau lawm los ntawm cov nkev roj yog ib qho tseem ceeb lav los daws qhov teeb meem ntawm pheej yig hydrogen qhov chaw. Raws li lub zog muaj txiaj ntsig zoo thiab huv si, cov roj ntsha ntuj muaj lub tswv yim tseem ceeb hauv kev txhim kho lub zog hauv Suav teb. Vim tias cov roj ntsha ntuj tsis yog tsuas yog roj tseem ceeb rau tib neeg lub neej txhua hnub, tab sis kuj yog cov khoom siv raw ntawm ntau cov khoom siv tshuaj lom neeg.

Hydrogen ntau lawm los ntawm natural gas yog ib qho ntawm ntau yam khoom siv roj ntsha. Liaohe Oilfield, yog qhov thib peb loj tshaj plaws roj thiab roj teb hauv Suav teb, yog nplua nuj nyob rau hauv natural gas resources, tshwj xeeb tshaj yog nyob rau hauv cov roj thiab roj centralized ua lag luam. Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj ntau lawm, peb tuaj yeem tsim ib qho kev ntsuas ntawm cov roj qhuav sib txuas, uas muaj cov xwm txheej tshwj xeeb rau kev ua cov roj nkev sib sib zog nqus, Nws muaj qhov tseem ceeb tshaj plaws rau kev txhawb nqa kev txhim kho thiab nrov ntawm cov txheej txheem tsim cov roj hydrogen.

Kev xaiv thiab theoretical tsom xam ntawm hydrogen ntau lawm los ntawm natural gas

Raws li cov khoom siv tshuaj thib ob, hydrogen yog siv dav hauv kev lag luam tshuaj, tshuaj zoo, hluav taws xob thiab hluav taws xob kev lag luam. Tshwj xeeb, hydrogen, raws li cov roj xav tau rau cov roj hlwb, yuav muaj kev lag luam dav dav hauv kev thauj mus los thiab lub zog tsim hluav taws xob yav tom ntej, thiab yuav tuav txoj haujlwm tseem ceeb hauv lub zog yav tom ntej. Cov txheej txheem tsim cov hydrogen ib txwm muaj, xws li lub teeb hydrocarbon chav hloov pauv, dej electrolysis, methanol tawg, thee gasification thiab ammonia decomposition, kuj paub tab. Txawm li cas los xij, muaj "ib qho siab thiab ob qho qis" cov teeb meem xws li tus nqi siab, tsis muaj txiaj ntsig thiab kev ua haujlwm tsawg. Nyob rau hauv cov txheej txheem ntawm cov roj thiab roj ntau lawm hauv Liaohe Oilfield, muaj cov khoom siv hydrocarbon xws li roj qhuav thiab naphtha. Kev siv cov qauv no los tsim cov hydrogen tuaj yeem ua rau kev siv cov peev txheej loj tshaj plaws. Tsis tas li ntawd, lub ntsiab tseem ceeb ntawm cov pa roj carbon monoxide yog methane, uas tuaj yeem hloov mus rau hauv hydrogen los ntawm hydrocarbon chav, nrog kev ua haujlwm siab purity thiab kev ua haujlwm siab.

Txheej txheem txheej txheem ntawm hydrogen ntau lawm los ntawm natural gas

Cov txheej txheem tseem ceeb ntawm cov nkev muaj xws li atmospheric thiab nqus distillation, catalytic cracking, catalytic reforming thiab aromatics ntau lawm. Nyob rau tib lub sijhawm, nws suav nrog kev siv roj ntsha ntuj, sib sau ua ke thiab sib kis thiab ua kom huv. Nyob rau hauv tej yam siab, kub thiab catalyst, alkanes thiab chav nyob rau hauv tej yam ntuj tso roj reacts chemically. Cov roj reforming nkag mus rau lub converter tom qab tshav kub pauv hauv boiler kom hloov CO rau hauv H2 thiab CO2. Tom qab kev sib pauv cua sov, condensation thiab chav dej sib cais, cov roj tau dhau los ntawm ntauwd adsorption nruab nrog peb qhov tshwj xeeb adsorbents los ntawm kev tswj hwm kev tswj hwm, thiab N2, Co, CH4 thiab CO2 yog pressurized thiab adsorbed los ntawm siab viav vias adsorption (PSA) kom rho tawm cov khoom. hydrogen. Kev tsom xam depressurization tso tawm impurities thiab rov tsim cov adsorbent

Reaction formula: CH4 + H2O → CO + 3h2-q CO + H2O → CO2 + H2 + Q
