Process

Kugadzirwa kweHydrogen kubva kugasi rechisikigo ndeyekuita kemikari yekudzvinyirirwa uye yakasvibiswa gasi rechisikigo uye chiutsi mune yakakosha reformer inozadza necatalyst uye kugadzira gasi rekugadzirisa neH₂, CO₂ neCO, shandura CO mumagasi ekuchinja kuita CO₂ uye wobva wabvisa. inokwanisa H₂ kubva kumagasi ekugadzirisa nekumanikidza swing adsorption (PSA).

Iyo Hydrogen Production Plant dhizaini uye kusarudzwa kwemidziyo mhedzisiro kubva kune yakakura TCWY engineering zvidzidzo uye kuongororwa kwevatengesi, kunyanya kuvandudza zvinotevera:

1. Kuchengetedza uye Kusununguka kwekushanda

2. Kuvimbika

3. Short equipment delivery

4. Basa shoma remumunda

5. Mari yemakwikwi uye mari yekushandisa

(1) Natural Gasi Desulfurization

Pane imwe tembiricha uye kumanikidzwa, negasi rekudya kuburikidza neiyo oxidation ye manganese uye zinc oxide adsorbent, iyo yakazara sarufa mugasi rekudya ichabviswa pazasi 0.2ppm pazasi kuti isangane nezvinodiwa zvezvinokonzeresa zvekuchinja kweutsi.

Mhedzisiro huru ndeye:

COS+MnOjtMnS+CO2

MnS+H2OjtMnS+H2O

H2S+ZnOjtZnS+H2O

(2) NG Steam Kugadzirisa

Steam reforming process inoshandisa mhute yemvura seyo oxidant, uye ne nickel catalyst, ma hydrocarbons anozo gadziridzwa kuita gasi mbishi kugadzira hydrogen gasi.Iyi maitiro ndeye endothermic process iyo inoda kupisa kupihwa kubva kuchikamu chemwaranzi cheFurnace.

Mhedzisiro huru pamberi penickel catalysts ndeiyi inotevera:

CnHm+nH2O = nCO+(n+m/2)H2

CO+H2O = CO2+H2     △H°298= – 41KJ/mol

CO+3H2 = CH4+H2O △H°298= – 206KJ/mol

(3) PSA Kucheneswa

Sekuita kwechikamu chemakemikari, tekinoroji yePSA yekuparadzanisa gasi yave kukurumidza kukura kuita yakazvimirira chirango, uye ichiwedzera uye ichishandiswa zvakanyanya muminda yepetrochemical, makemikari, simbi, zvemagetsi, dziviriro yenyika, mushonga, indasitiri yemwenje, kurima uye kuchengetedza kwezvakatipoteredza. maindasitiri, nezvimwewo. Parizvino, PSA yave nzira huru yeH2kupatsanurwa kwave kuchishandiswa zvakabudirira kuchenesa uye kupatsanurwa kwekabhoni dioxide, kabhoni monoxide, nitrogen, okisijeni, methane uye mamwe magasi emaindasitiri.

Chidzidzo ichi chinowona kuti zvimwe zvinhu zvakasimba zvine chimiro chakanaka cheporous chinogona kutora mamorekuru emvura, uye zvinhu zvinonyudza zvakadaro zvinonzi zvinonyudza.Kana iyo mamorekuru emvura anobata yakasimba adsorbents, iyo adsorption inoitika nekukurumidza.Iyo adsorption inoguma mukusangana kwakasiyana kwemamorekuru akatorwa mumvura uye pane inonyudza.Uye iyo adsorbed molecules neinomwisa ichave yakafumiswa pamusoro payo.Semazuva ese, mamorekuru akasiyana acharatidza hunhu hwakasiyana kana akabatwa nema adsorbents.Zvakare iwo ekunze mamiriro akadai seyemvura tembiricha uye kusungirirwa (kudzvanywa) kuchakanganisa zvakananga izvi.Nokudaro, nekuda kwemhando iyi yemhando dzakasiyana-siyana, nekuchinja kwekushisa kana kudzvinyirira, tinogona kuwana kuparadzaniswa uye kucheneswa kwemusanganiswa.

Kune iyi chirimwa, akasiyana adsorbent akazadzwa mumubhedha wekushongedza.Kana gasi rekuchinja (gasi musanganiswa) richiyerera richipinda mukoramu yeadsorption (adsorption bed) pasi pekumanikidzwa, nekuda kweakasiyana adsorption maitiro eH.2, CO, CH2, CO2, nezvimwewo iyo CO, CH2uye CO2adsorbents, nepo H2ichayerera ichibva pamusoro pemubhedha kuti iwane chigadzirwa chehydrogen.
