Biogas kupita ku CNG/LNG Plant

Mafotokozedwe Akatundu

Kupyolera mu mndandanda wa mankhwala oyeretsera monga desulfurization, decarbonization ndi kutaya madzi m'thupi la biogas, gasi waukhondo komanso wopanda kuipitsidwa akhoza kupangidwa, zomwe zimawonjezera kwambiri kuyaka kwake kwa calorific.Decarbonized mchira mpweya angathenso kutulutsa madzi mpweya woipa, kuti biogas akhoza mokwanira ndi mogwira ntchito, ndipo sadzabala kuipitsa yachiwiri.

Malinga ndi zofunikira za chinthu chomaliza, gasi wachilengedwe amatha kupangidwa kuchokera ku biogas, yomwe imatha kutumizidwa ku netiweki ya chitoliro cha gasi ngati gasi wamba;Kapena CNG (gasi woponderezedwa wamagalimoto) amatha kupangidwa ngati mafuta agalimoto popondereza gasi wachilengedwe ku 20 ~ 25MPa;Ndizothekanso kusungunula gasi wopangidwa ndi cryogenically ndipo pamapeto pake kutulutsa LNG (gasi wachilengedwe wokhala ndi liquefied).

Njira yopangira biogas ya CNG kwenikweni ndi njira zingapo zoyeretsera komanso njira yomaliza yokakamiza.
1. Sulfure yochuluka iwononga zida ndi mapaipi ndikuchepetsa moyo wawo wautumiki;
2. Kuchuluka kwa CO₂, kumachepetsa mtengo wa calorific wa gasi;
3. Popeza mpweya wa biogas umapangidwa m'malo opanda mpweya, mpweya wa O₂zomwe zili sizingadutse muyezo, koma ziyenera kudziwidwa kuti O₂zokhutira sizidzakhala zapamwamba kuposa 0.5% pambuyo kuyeretsedwa.
4. Poyendetsa mapaipi achilengedwe a gasi, madzi amasungunuka kukhala madzi kutentha pang'ono, zomwe zingachepetse gawo la payipi, kuwonjezera kukana ndi kugwiritsa ntchito mphamvu pamayendedwe, ngakhale kuzizira ndi kutsekereza payipi;Kuphatikiza apo, kukhalapo kwa madzi kumathandizira kuwononga kwa sulfide pazida.

Malinga ndi magawo oyenera a biogas yaiwisi ndi kusanthula zofunika mankhwala, yaiwisi biogas akhoza motsatizana desulfurization, pressurization kuyanika, decarbonization, CNG pressurization ndi njira zina, ndi mankhwala angapezeke: wothinikizidwa CNG galimoto.
