Kanema
Kupanga haidrojeni kuchokera ku gasi wachilengedwe ndikupangitsa momwe gasi wachilengedwe woponderezedwa komanso wosasunthika ndi nthunzi munjira yapadera yokonzanso ndikudzaza ndi chothandizira ndikupanga mpweya wokonzanso ndi H₂, CO₂ ndi CO, kutembenuza CO mumipweya yokonzanso kukhala CO₂ kenako ndikuchotsa. oyenerera H₂ kuchokera ku mipweya yokonzanso ndi pressure swing adsorption (PSA).
Mapangidwe a Hydrogen Production Plant ndi kusankha kwa zida kumachokera ku maphunziro aukadaulo a TCWY komanso kuwunika kwa ogulitsa, ndikukwaniritsa izi:
1. Chitetezo ndi Kusavuta kugwira ntchito
2. Kudalirika
3. Short zida yobereka
4. Ntchito zochepa zakumunda
5. Ndalama zopikisana ndi ndalama zogwirira ntchito
(1) Kuwononga Gasi Wachilengedwe
Pa kutentha kwina ndi kupanikizika, ndi mpweya wa chakudya kudzera mu okosijeni wa manganese ndi zinc oxide adsorbent, sulfure yonse mu gasi wa chakudya imakhala pansi pa 0.2ppm pansipa kuti ikwaniritse zofunikira za zoyambitsa kusintha kwa nthunzi.
Zomwe zimachitika kwambiri ndi:
| COS+MNO |
| MnS+H2O |
| H2S+ZnO |
(2) NG Kusintha kwa Steam
Njira yosinthira nthunzi imagwiritsa ntchito mpweya wamadzi monga okosijeni, ndipo pogwiritsa ntchito nickel catalyst, ma hydrocarbons adzasinthidwa kukhala mpweya waiwisi wopangira mpweya wa haidrojeni. Njirayi ndi njira ya endothermic yomwe imafuna kutentha kuchokera kugawo la ng'anjo.
Chochita chachikulu pamaso pa nickel catalysts ndi motere:
| CnHm+nH2O = nCO+(n+m/2)H2 |
| CO+H2O = CO2+H2 △H°298= – 41KJ/mol |
| CO+3H2 = CHA4+H2O △H°298= – 206KJ/mol |
(3) Kuyeretsedwa kwa PSA
Monga ndondomeko ya mankhwala wagawo, PSA mpweya kulekana luso wakhala mofulumira kukula mu chilango palokha, ndipo zambiri ankagwiritsa ntchito m'madera a petrochemical, mankhwala, zitsulo, zamagetsi, chitetezo dziko, mankhwala, makampani kuwala, ulimi ndi kuteteza chilengedwe. mafakitale, ndi zina zotero. Pakali pano, PSA yakhala njira yaikulu ya H2kulekana kumene wakhala bwinobwino ntchito kuyeretsedwa ndi kulekana kwa mpweya woipa, mpweya monoxide, asafe, mpweya, methane ndi mpweya ena mafakitale.
Kafukufukuyu adapeza kuti zida zina zolimba zokhala ndi porous bwino zimatha kuyamwa mamolekyu amadzimadzi, ndipo zoyamwa zotere zimatchedwa absorbent. Mamolekyu amadzimadzi akamalumikizana ndi ma adsorbents olimba, kutsatsa kumachitika nthawi yomweyo. Kutengeka kumeneku kumapangitsa kuti mamolekyu alowe m'madzi amadzimadzi ndi pamtunda wosiyana. Ndipo ma adsorbed mamolekyu ndi chotengera chidzalemeretsedwa pamwamba pake. Monga mwachizolowezi, mamolekyu osiyanasiyana amawonetsa mawonekedwe osiyanasiyana akamwedwa ndi ma adsorbents. Komanso zinthu zakunja monga kutentha kwamadzi ndi ndende (kupanikizika) zidzakhudza izi. Choncho, chifukwa cha mtundu uwu wa makhalidwe osiyanasiyana, ndi kusintha kwa kutentha kapena kupanikizika, tikhoza kukwaniritsa kulekana ndi kuyeretsedwa kwa kusakaniza.
Kwa chomera ichi, ma adsorbent osiyanasiyana amadzazidwa mu bedi la adsorption. Pamene mpweya wokonzanso (kusakaniza kwa gasi) umalowa m'kati mwa adsorption (bedi la adsorption) pansi pa kupanikizika kwina, chifukwa cha kusiyana kwa ma adsorption a H.2, KO, C2, CO2, ndi zina zotero. CO, CH2ndi CO2Amakhala ndi adsorbents, pomwe H2idzatuluka pamwamba pa bedi kuti ipeze mankhwala oyenerera a haidrojeni.
