I-Biogas kwi-CNG / LNG Plant

Ingcaciso yeMveliso

Ngoluhlu lwezonyango zokuhlanjululwa ezifana ne-desulfurization, i-decarbonization kunye nokuchithwa kwe-biogas, igesi yendalo ecocekileyo kunye nongcoliseko ingaveliswa, eyandisa kakhulu ixabiso layo le-calorific yokutsha.Irhasi ye-Decarbonized tail can also live liquid carbon dioxide, ukuze i-biogas isetyenziswe ngokupheleleyo nangempumelelo, kwaye ayiyi kuvelisa ungcoliseko lwesibini.

Ngokweemfuno zemveliso yokugqibela, igesi yendalo inokuveliswa kwi-biogas, enokuthi ihanjiswe ngokuthe ngqo kuthungelwano lwemibhobho yegesi yendalo njengegesi yoluntu;Okanye i-CNG (igesi yendalo ecinezelweyo yezithuthi) inokwenziwa njengamafutha esithuthi ngokucinezela igesi yendalo ukuya kuma-20 ~ 25MPa;Kwakhona kunokwenzeka ukuba i-cryogenically liquefy igesi yemveliso kwaye ekugqibeleni ivelise i-LNG (i-liquefied natural gas).

Inkqubo yokuveliswa kwe-biogas ye-CNG ngokwenene yinkqubo yokucoca kunye nenkqubo yokugqibela yoxinzelelo.
1. Isiqulatho sesulfure esiphezulu siya kudla izixhobo kunye nemibhobho kwaye sinciphise ubomi babo benkonzo;
2. Iphezulu isixa seCO₂, iphantsi ixabiso le-calorific yegesi;
3. Ekubeni i-biogas iveliswa kwindawo ye-anaerobic, i-O₂Umxholo awuyi kudlula umgangatho, kodwa kufuneka kuqatshelwe ukuba i-O₂umxholo awuyi kuba ngaphezulu kwe-0.5% emva kokucoca.
4. Kwinkqubo yokuthuthwa kwemibhobho yerhasi yendalo, amanzi ajiya abe lulwelo kwiqondo lobushushu eliphantsi, nto leyo eya kunciphisa indawo enqamlezileyo yombhobho, yandise ukuxhathisa kunye nokusetyenziswa kwamandla kwinkqubo yothutho, kwaye ide ibe ngumkhenkce kwaye ivale umbhobho;Ukongezelela, ubukho bamanzi buya kukhawulezisa ukubola kwe-sulfide kwizixhobo.

Ngokweeparamitha ezifanelekileyo ze-biogas eluhlaza kunye nohlalutyo lweemfuno zemveliso, i-biogas eluhlaza ingaba yi-desulfurization ngokulandelanayo, i-pressurization drying, i-decarbonization, i-CNG pressurization kunye nezinye iinkqubo, kwaye imveliso inokufumaneka: i-CNG ecinezelweyo yesithuthi.
