Hydrogen imagwiritsidwa ntchito kwambiri muzitsulo, zitsulo, mafakitale a mankhwala, zamankhwala, mafakitale opepuka, zomangira, zamagetsi ndi zina. Ukadaulo wokonzanso methanol kuti upangitse haidrojeni uli ndi zabwino zotsika mtengo, palibe kuipitsa, komanso kugwira ntchito kosavuta. Amagwiritsidwa ntchito kwambiri mumitundu yonse yamafuta a haidrojeni.
Sakanizani methanol ndi madzi mu gawo lina, pressurize, kutentha, nthunzi ndi kutenthetsa zinthu osakaniza kufika kutentha ndi kupanikizika, ndiye pamaso pa chothandizira, methanol akulimbana anachita ndi CO kusuntha anachita kuchita pa nthawi yomweyo, ndi kupanga kusakaniza kwa gasi ndi H2, CO2 ndi CO2 yotsalira yotsalira.
Njira yonseyi ndi njira ya endothermic. Kutentha kofunikira pakuchitapo kumaperekedwa kudzera mukuyenda kwa mafuta opangira kutentha.
Kupulumutsa kutentha mphamvu, osakaniza mpweya kwaiye mu riyakitala amapanga kutentha kuwombola ndi zinthu osakaniza madzi, ndiye condens, ndi kutsukidwa mu chiyeretso nsanja. The osakaniza madzi kuchokera condensation ndi kuchapa ndondomeko analekanitsidwa mu chiyeretso nsanja. The zikuchokera osakaniza madzimadzi makamaka madzi ndi methanol. Zimatumizidwanso ku thanki yazinthu zopangira kuti zibwezeretsedwe. The oyenerera cracking mpweya ndiye anatumizidwa PSA unit.
Makhalidwe Aukadaulo
1. High intensification (standard modularization), maonekedwe wosakhwima, mkulu kusinthasintha pa malo yomanga: chipangizo chachikulu pansipa 2000Nm3/ h ikhoza kugulidwa ndikuperekedwa yonse.
2. Kusiyanasiyana kwa njira zotenthetsera: chothandizira makutidwe ndi okosijeni Kutentha; Self-kutentha chitoliro mpweya kufalitsidwa Kutentha; Kutentha kwamafuta opangira mafuta opangira ng'anjo; Kuwotcha kwamagetsi Kutentha kwamafuta opangira mafuta.
3. Kutsika kwa zinthu ndi kugwiritsa ntchito mphamvu, mtengo wotsika mtengo: kugwiritsa ntchito methanol osachepera 1Nm3hydrogen imatsimikiziridwa kukhala <0.5kg. Kugwiritsa ntchito kwenikweni ndi 0.495kg.
4. Kubwezeretsanso kwamphamvu kwamphamvu ya kutentha: kukulitsa kugwiritsa ntchito mphamvu za kutentha ndikuchepetsa kutentha ndi 2%;
5. Ukadaulo wokhwima, wotetezeka komanso wodalirika
6. Kufikika yaiwisi gwero, mayendedwe yabwino ndi kusunga
7. Njira yosavuta, makina apamwamba, osavuta kugwiritsa ntchito
8. Wokonda zachilengedwe, Kuipitsa kwaulere
Sakanizani methanol ndi madzi mu gawo lina, pressurize, kutentha, nthunzi ndi kutenthetsa zinthu osakaniza kufika kutentha ndi kupanikizika, ndiye pamaso pa chothandizira, methanol akulimbana anachita ndi CO kusuntha anachita kuchita pa nthawi yomweyo, ndi kupanga kusakaniza gasi ndi H2, CO2ndi zochepa za CO zotsalira.
Methanol cracking ndi njira yovuta yochitira zinthu zambiri ndi magesi angapo komanso zolimba zamakina
Zochita zazikulu:
| CH3OH |
| CO + H2O |
Ndemanga mwachidule:
CH3OH + H2O CO2+ 3H ndi2- 49.5 kJ / mol |
Njira yonseyi ndi njira ya endothermic. Kutentha kofunikira pakuchitapo kumaperekedwa kudzera mukuyenda kwa mafuta opangira kutentha.
Kupulumutsa kutentha mphamvu, mpweya osakaniza kwaiye mu riyakitala kupanga kutentha kusinthana ndi zinthu osakaniza madzi, ndiye condens, ndi kutsukidwa mu chiyeretso nsanja. The osakaniza madzi kuchokera condensation ndi kuchapa ndondomeko analekanitsidwa mu chiyeretso nsanja. The zikuchokera osakaniza madzimadzi makamaka madzi ndi methanol. Zimatumizidwanso ku thanki yazinthu zopangira kuti zibwezeretsedwe. The oyenerera cracking mpweya ndiye anatumizidwa PSA unit.
Pressure Swing Adsorption (PSA) imachokera ku kutengeka kwa ma molekyulu a gasi mkati mwa adsorbent inayake (porous solid material). The adsorbent ndi yosavuta adsorb mkulu-kuwira zigawo zikuluzikulu ndi zovuta adsorb otsika otentha zigawo zikuluzikulu pa kuthamanga chomwecho. Kuchuluka kwa adsorption kumawonjezera kupsinjika kwakukulu ndikuchepa pansi pamavuto otsika. Pamene mpweya wa chakudya umadutsa pabedi la adsorption pansi pa kukanikiza kwina, zonyansa zotentha kwambiri zimadyedwa mosankhidwa ndipo hydrogen yotentha yotsika kwambiri yomwe simatengeka mosavuta imatuluka. Kulekanitsa kwa haidrojeni ndi zigawo zonyansa kumatheka.
Pambuyo pa ndondomeko ya adsorption, adsorbent amachotsa zonyansa zowonongeka pamene amachepetsa kupanikizika kotero kuti akhoza kubwezeretsedwanso ku adsorb ndikulekanitsa zonyansa kachiwiri.
1. H2 Recycling kuchokera ku H2-rich gas mix (PSA-H2)
Chiyero: 98% ~ 99.999%
2. Kupatukana ndi kuyeretsedwa kwa CO2 (PSA - CO2)
Kuyera: 98-99.99%.
3. Kupatukana kwa CO ndi Kuyeretsa (PSA - CO)
Chiyero: 80% ~ 99.9%
4. Kuchotsa CO2 (PSA - CO2 Removal)
Chiyero: <0.2%
5. PSA - C₂+ Kuchotsa
* The VPSA mpweya kupanga ndondomeko zida "mwamakonda" kamangidwe malinga ndi wosuta osiyanasiyana okwera, zinthu meteorological, chipangizo kukula, mpweya chiyero (70% ~ 93%).
