Tabudirira kupedzisa kugadzira nekutumira 300Nm3 /h mutambo wekutumira hydrogen yeSinopec yakapararira ine gasi remethane rakapfuma. Pano ndinoda kupa sumo pfupi yemaitiro ekugadzira hydrogen kubva mugasi rechisikigo.
Nekuwedzera kwekushandiswa kwesimba, kutsvaga simba idzva kwave basa rakakosha. Sesimba rinogona kushandiswa zvakanyanya, hydrogen ine manyuko akasiyana-siyana, hapana kusvibiswa, kushanda zvakanaka kwekushandura simba uye mikana yakawanda yekushandisa simba. Kugadzirwa kwehydrogen kubva mugasi rechisikigo kunogona kuderedza dambudziko resimba muChina kusvika pamwero wakati uye kukurudzira kushandurwa kwechimiro chekushandiswa kwesimba muChina.
Pepa rino richatarisa papfungwa yekugadzirwa kwehydrogen kubva mugasi rechisikigo, maitiro uye tekinoroji yekugadzirwa kwehydrogen kubva mugasi rechisikigo, kupatsanurwa kwetekinoroji yekugadzira hydrogen kubva mugasi rechisikigo uye kuverengerwa kwemari yekugadzirwa kwehydrogen kubva mugasi rechisikigo.
1 Nheyo uye maitiro e kugadzirwa kwehydrogen kubva mugasi rechisikigo
1.1Nheyo yekugadzira hydrogen kubva mugasi rechisikigo
Nheyo yekugadzira hydrogen gasi rechisikigo ndeyekutanga gasi rechisikigo, wozoshandura methane nesteam kuita carbon monoxide nehydrogen mu reformer, uye woshandura carbon monoxide kuita carbon dioxide nehydrogen mushift tower mushure mekudzoreredza kupisa kwetsvina. Hwaro hweiyi process tekinoroji hunowanikwa kuburikidza ne natural gas steam conversion technology. Mushift tower, reaction tembiricha inodzorwa kana paine catalyst, uye carbon monoxide mushift tower inopindirana nemvura kuti ibudise hydrogen necarbon dioxide.
Kana gasi iri mugasi rechisikigo rava kumanikidzwa uye tembiricha yakakodzera, ma alkanes ari mugasi rechisikigo anozosangana nemakemikari akawanda kuti agadzire gasi rekushandura. Mushure mekunge gasi rekushandura rapfuura nemuPAS device ine adsorbents dzakasiyana-siyana pasi pe automatic control, kabhoni monoxide, kabhoni dioxide nezvimwe tsvina zvichanyungudutswa ne adsorption tower, uye hydrogen ichatumirwa kugasi rinoshandisa gasi kuti inyungudutse adsorbent yetsvina. Mushure mekunyungudutswa, gasi re analytical rinogona kutumirwa kushift furnace semafuta, uye adsorbent inogonawo kugadzirwa patsva.
Nzira huru yekuita seinotevera:
Gasi rechisikigo nemvura zvinosangana pa800 ~ 900 ℃ uye nickel oxide catalyst zvichigadzira carbon monoxide nehydrogen.
Fomura yemhinduro ndeiyi: CH4 + H2O → CO + H2-Q
Carbon monoxide nemvura zvinosangana pa300-400 ℃ neferric oxide catalyst kuti zvigadzire carbon dioxide nehydrogen.
Fomura yekuita ndeye: CO + H2O → CO2 + H2 + Q
Pamusoro pezvo, zvinodiwa zvehunyanzvi hwekugadzira zvinhu mukugadzirira ndeizvi:
Kumanikidzwa kunowanzova 1.5 ~ 2.5 MPa, uye kushandiswa kwegasi rechisikigo kuri 0.4 ~ 0.5 m3 / m3 hydrogen;Nguva yekushanda: > 8000h;Chikero chemaindasitiri: 1000 m3 / H ~ 100000 m3 / h.
1.2 Maitiro ekugadzira hydrogen gasi rechisikigo
Maitiro ekugadzira hydrogen yegasi rechisikigo anosanganisira maitiro mana: kurapwa kwegasi rekudyisa, kushandurwa kwemhepo inopfungaira negasi rechisikigo, kushandurwa kwecarbon monoxide uye kuchenesa hydrogen.
Danho rekutanga ndere nhanho yekugadzirira gasi risina kugadzirwa. Kugadzirisa gasi iri pano kunonyanya kureva kubvisa sarufa mugasi risina kugadzirwa. Mukushanda chaiko, gasi rechisikigo cobalt molybdenum hydrogenation series zinc oxide inowanzo shandiswa se desulfurizer kushandura sarufa yeorganic mugasi rechisikigo kuita sarufa isina kugadzirwa wobva waibvisa. Kuyerera kwegasi rechisikigo risina kugadzirwa pano kwakakura, saka gasi rechisikigo rine kumanikidzwa kwakanyanya rinogona kushandiswa kana kuti mukana mukuru unogona kufungwa nezvawo pakusarudza compressor yegasi rechisikigo.
Danho rechipiri kushandurwa kwemhepo nemhepo. Nickel catalyst inoshandiswa mu reformer kushandura alkanes mugasi rechisikigo kuita gasi rekudyisa rine zvikamu zvikuru zve carbon monoxide ne hydrogen.
Zvadaro, kabhoni monoxide inoshandurwa kuti iite seyakasanganiswa nemvura ine simba kana paine catalyst kuti igadzire hydrogen nekabhoni dhayokisaidhi kuti iwane gasi rekushandura rine zvikamu zvikuru zviri hydrogen nekabhoni dhayokisaidhi. Zvichienderana netembiricha yakasiyana yekushandura, maitiro ekushandura kabhoni monoxide anogona kukamurwa kuita mhando mbiri: shanduko yetembiricha yepakati netembiricha yepamusoro. Tembiricha yekushandura tembiricha yepamusoro inenge 360 ℃, uye maitiro ekushandura tembiricha yepakati anenge 320 ℃. Nekuvandudzwa kwematanho ekudzivirira, maitiro maviri ekugadzirisa carbon monoxide yekushandura tembiricha yepamusoro netembiricha yakaderera akagamuchirwa mumakore achangopfuura, izvo zvinogona kuchengetedza kushandiswa kwezviwanikwa. Zvisinei, kana huwandu hwekabhoni monoxide mugasi rekushandura husina kukwira, chete shanduko yetembiricha yepakati ndiyo inogona kushandiswa.
Danho rekupedzisira nderekuchenesa hydrogen. Iye zvino sisitimu yekuchenesa hydrogen inonyanya kushandiswa iPAS system, inozivikanwawo sePSA purification and separation system. Iyi sisitimu inoshandisa simba shoma, maitiro ari nyore uye kuchena kwakanyanya kwekugadzirwa kwehydrogen. Pakukwirira, kuchena kwehydrogen kunogona kusvika 99.99%.
