Hydrogen ikoreshwa cyane mubyuma, metallurgie, inganda zimiti, ubuvuzi, inganda zoroheje, ibikoresho byubaka, ibikoresho bya elegitoroniki nizindi nzego. Methanol ivugurura tekinoroji yo kubyara hydrogène ifite ibyiza byo gushora imari mike, nta mwanda, no gukora byoroshye. Yakoreshejwe cyane muburyo bwose bwibimera bya hydrogène.
Kuvanga methanol namazi muburyo runaka, kanda, ushushe, ushushe kandi ushushe ibikoresho bivanze kugirango ugere ku bushyuhe n’umuvuduko runaka, hanyuma imbere ya catalizator, reaction ya methanol na reaction ya CO ikora icyarimwe, hanyuma ikabyara a gazi ivanze na H2, CO2 hamwe na CO isigaye.
Inzira yose ni inzira ya endothermic. Ubushyuhe bukenewe kuri reaction butangwa binyuze mukuzenguruka kwamavuta yo gutwara ubushyuhe.
Kugirango uzigame ingufu zubushyuhe, gaze ivanze ikorwa mumashanyarazi ituma habaho guhana ubushyuhe hamwe nuruvange rwibintu bivanze, hanyuma bigahinduka, hanyuma bigakaraba muminara yo kweza. Amazi avanze ava muri kondegene no gukaraba yatandukanijwe muminara yo kweza. Ibigize iyi mvange y'amazi ni amazi na methanol. Yoherejwe mu kigega kibisi cyo gutunganya. Gazi yujuje ibyangombwa noneho yoherezwa mubice bya PSA.
Ibiranga tekiniki
13/ h irashobora gusimburwa no gutangwa muri rusange.
2. Gutandukanya uburyo bwo gushyushya: gushyushya okiside ya catalitiki; Kwishyushya ubwikorezi bwa flue gaze kuzenguruka; Gushyushya amavuta yo gutwika amavuta; Gushyushya amashanyarazi gushyushya amavuta.
3. Gukoresha ibikoresho bike ningufu, igiciro gito cyumusaruro: gukoresha methanol byibuze ya 1Nm3hydrogen yemerewe kuba <0.5kg. Igikorwa nyacyo ni 0.495kg.
4. Kugarura ibyiciro byingufu zubushyuhe: gukoresha ingufu zubushyuhe no kugabanya ubushyuhe bwa 2%;
5. Ikoranabuhanga rikuze, rifite umutekano kandi ryizewe
6. Inkomoko yibikoresho byoroshye, gutwara no kubika neza
7. Uburyo bworoshye, automatike yo hejuru, byoroshye gukora

Kuvanga methanol namazi muburyo runaka, kanda, ushushe, ushushe kandi ushushe ibikoresho bivanze kugirango ugere ku bushyuhe n’umuvuduko runaka, hanyuma imbere ya catalizator, reaction ya methanol na reaction ya CO ikora icyarimwe, hanyuma ikabyara a gazi ivanze na H.2, CO2n'umubare muto wa CO usigaye.
Kumena Methanol ni ibintu bigoye cyane bigizwe na gaze nyinshi hamwe nubushakashatsi bukomeye
Ibisubizo nyamukuru:
| CH3OH |
| CO + H.2O. |
Incamake:
CH3OH + H.2O. CO2+ 3H2- 49.5kJ / mol |
Inzira yose ni inzira ya endothermic. Ubushyuhe bukenewe kuri reaction butangwa binyuze mukuzenguruka kwamavuta yo gutwara ubushyuhe.
Kugirango uzigame ingufu zubushyuhe, gazi ivanze ikorwa mubushyuhe bwo guhinduranya ubushyuhe hamwe nibintu bivanze byamazi, hanyuma bigahinduka, hanyuma bigakaraba muminara yo kweza. Amazi avanze ava muri kondegene no gukaraba yatandukanijwe muminara yo kweza. Ibigize iyi mvange y'amazi ni amazi na methanol. Yoherejwe mu kigega kibisi cyo gutunganya. Gazi yujuje ibyangombwa noneho yoherezwa mubice bya PSA.
Umuvuduko wa Swing Adsorption (PSA) ushingiye kumyuka yumubiri wa molekile ya gaze hejuru yimbere ya adsorbent yihariye (ibintu bikomeye). Amatangazo yamamaza byoroshye kwamamaza ibice byinshi bitetse kandi biragoye kwamamaza adsorb ibice bitetse kumuvuduko umwe. Umubare wa adsorption wongera sunder umuvuduko mwinshi kandi ugabanuka kumuvuduko muke. Iyo gazi yo kugaburira inyuze mu buriri bwa adsorption munsi yumuvuduko runaka, umwanda mwinshi utetse uhitamo guhitamo kandi hydrogène itetse cyane itorohewe cyane irasohoka. Gutandukanya hydrogène nibigize umwanda biragerwaho.
Nyuma yuburyo bwa adsorption, adsorbent yangiza umwanda winjiye mugihe ugabanya umuvuduko kugirango ishobore gusubirwamo kuri adsorb no kongera gutandukanya umwanda.
1. H2 Gusubiramo biva muri H2 ikungahaye kuri gaze (PSA-H2)
Isuku: 98% ~ 99,999%
2. CO2 Gutandukanya no kwezwa (PSA - CO2)
Isuku: 98 ~ 99,99%.
3. Gutandukanya CO no kwezwa (PSA - CO)
Isuku: 80% ~ 99.9%
4. Gukuraho CO2 (PSA - Gukuraho CO2)
Isuku: <0.2%
5. PSA - C₂ + Gukuraho
* VPSA itanga umusaruro wa ogisijeni ishyira mubikorwa "byashizweho" ukurikije ubutumburuke bwumukoresha, imiterere yubumenyi bwikirere, ingano yibikoresho, ubuziranenge bwa ogisijeni (70% ~ 93%).
