- 380-420 Nm³ / h natural gas
- 900 kg / h boiler pub dej
- 28 kW fais fab tuag
- 38 m³ / h dej txias *
- * tuaj yeem hloov tau los ntawm cua txias
- By-product: export chav, yog tias xav tau
Hydrogen ntau lawm los ntawm cov nkev nkev yog ua cov tshuaj tiv thaiv ntawm pressurized thiab desulfurized natural gas thiab chav nyob rau hauv ib tug tshwj xeeb reformer sau nrog catalyst thiab tsim cov roj reforming nrog H₂, CO₂ thiab CO, hloov cov CO nyob rau hauv lub transforming gases rau CO₂ thiab ces rho tawm. Tsim nyog H₂ los ntawm kev hloov pauv roj los ntawm lub siab viav vias adsorption (PSA).
Hydrogen Production Plant tsim thiab xaiv cov khoom siv tau los ntawm kev tshawb fawb txog TCWY engineering thiab cov neeg muag khoom, tshwj xeeb tshaj yog ua kom zoo dua cov hauv qab no:
1. Kev nyab xeeb thiab kev ua haujlwm yooj yim
2. Kev ntseeg tau
3. Kev xa khoom luv luv
4. Yam tsawg kawg nkaus ua haujlwm
5. Kev sib tw peev thiab cov nqi khiav haujlwm
(1) Natural Gas Desulfurization
Ntawm qhov kub thiab txias, nrog rau cov pa roj los ntawm oxidation ntawm manganese thiab zinc oxide adsorbent, tag nrho cov sulfur hauv cov pa roj yuav tawm hauv qab 0.2ppm hauv qab no kom tau raws li cov kev xav tau ntawm cov catalysts rau kev hloov pauv chav.
Cov tshuaj tiv thaiv tseem ceeb yog:
| COS + MnO |
| MnS + H2O |
| H2S + ZnO |
(2) NG Chav Reforming
Cov txheej txheem kev hloov pauv chav siv dej vapor ua cov oxidant, thiab los ntawm cov nickel catalyst, cov hydrocarbons yuav raug hloov kho los ua cov roj nyoos rau kev tsim cov roj hydrogen.Cov txheej txheem no yog cov txheej txheem endothermic uas xav tau cov khoom siv cua sov los ntawm cov hluav taws xob ntawm qhov cub.
Lub ntsiab cov tshuaj tiv thaiv nyob rau hauv lub xub ntiag ntawm nickel catalysts yog raws li nram no:
| CnHm+nH2O = nCO+(n+m/2)H2 |
| CO + H2O = CO2+H2 △ H°298 = – 41KJ/mol |
| CO + 3 H2 = CH4+H2O △H°298 = – 206KJ/mol |
(3) PSA Purification
Raws li cov txheej txheem ntawm chav tsev tshuaj, PSA roj sib cais tshuab tau tsim sai sai rau hauv kev qhuab qhia ywj pheej, thiab ntau thiab ntau tau siv dav hauv kev lag luam ntawm petrochemical, tshuaj, metallurgy, electronics, kev tiv thaiv hauv tebchaws, tshuaj, kev lag luam teeb, kev ua liaj ua teb thiab kev tiv thaiv ib puag ncig. kev lag luam, thiab lwm yam Tam sim no, PSA tau dhau los ua cov txheej txheem tseem ceeb ntawm H2Kev sib cais uas nws tau ua tiav siv rau kev ua kom huv thiab sib cais ntawm carbon dioxide, carbon monoxide, nitrogen, oxygen, methane thiab lwm yam kev lag luam gases.
Txoj kev tshawb nrhiav pom tias qee cov khoom siv nrog cov qauv ntxeem tau zoo tuaj yeem nqus tau cov kua dej molecules, thiab cov khoom siv absorbent no hu ua absorbent.Thaum cov kua dej molecules hu rau cov khoom adsorbents, cov adsorption tshwm sim tam sim ntawd.Lub adsorption ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm absorbed molecules hauv cov kua thiab ntawm qhov nqus dej.Thiab cov adsorbed molecules los ntawm lub absorbent yuav enriched ntawm nws nto.Raws li ib txwm muaj, sib txawv molecules yuav qhia cov yam ntxwv sib txawv thaum absorbed los ntawm cov adsorbents.Tsis tas li ntawd, cov xwm txheej sab nraud xws li dej kub thiab qhov siab (siab) yuav cuam tshuam ncaj qha rau qhov no.Yog li ntawd, tsuas yog vim muaj cov yam ntxwv sib txawv no, los ntawm kev hloov pauv ntawm qhov kub thiab txias, peb tuaj yeem ua tiav qhov kev sib cais thiab kev ua kom huv ntawm qhov sib tov.
Rau cov nroj tsuag no, ntau yam adsorbent tau ntim rau hauv lub txaj adsorption.Thaum cov roj hloov pauv (cov roj sib tov) ntws mus rau hauv cov khoom siv adsorption (adsorption txaj) nyob rau hauv ib lub siab, vim qhov txawv adsorption yam ntxwv ntawm H.2, CO, CH2, CO2, etc. the CO, CH2thiab CO2Nws yog adsorbed los ntawm cov adsorbents, thaum H2yuav ntws tawm ntawm saum txaj kom tau txais cov khoom tsim nyog hydrogen.
