Zolinga zochepetsera mpweya zimatheka pogwiritsa ntchito mafuta ochepa opaka mafuta
Kutulutsa mpweya wa carbon dioxide padziko lonse lapansi kuyenera kuchepetsedwa ndi 45 peresenti pofika chaka cha 2030 kuchokera mumiyezo ya 2010, ndikufikira mpweya wopanda ziro pofika 2050.
Malinga ndi bungwe la Intergovernmental Panel on Climate Change (IPCC), mpweya wotenthetsera mpweya mu 2004 unali 49 biliyoni wa t-CO2, womwe, wogawidwa ndi anthu 6.4 biliyoni padziko lapansi, ndi 7.66 t-CO2 pa munthu pachaka.Kuchuluka kwa mpweya wotenthetsa dziko lapansi womwe dziko lapansi lingatenge mwachilengedwe akuganiza kuti ndi 11.4 biliyoni t-CO2.Pogawikana ndi chiwerengero cha anthu padziko lonse lapansi cha 9.2 biliyoni mu 2050, izi zikutanthauza kuti dziko lapansi likhoza kuyamwa 1.24 t-CO2 pa munthu mu 2050. Uku ndikuchepetsa pafupifupi 80% kuchoka pa 7.66 t-CO2 pa munthu aliyense mu 2004.
Zolinga zotulutsa mpweya wa CO2 zomwe zakhazikitsidwa mu Eco Vision 2050 zatengera njira yochepetsera mpweya wotenthetsera mpweya pa munthu aliyense kufika pamlingo womwe dziko lapansi lingatenge mwachilengedwe.Zolinga zomwe zidzakwaniritsidwe pofika chaka cha 2030 zakhazikitsidwa pogwiritsa ntchito backcasting kuchokera ku Eco Vision 2050. Ndondomeko ikuchitika kuti akhazikitse ndondomeko yapakati pazaka zapakati pa chilengedwe cha 2019 pogwiritsa ntchito backcasting kuchokera ku zolinga zomwe zidzakwaniritsidwe pofika chaka cha 2030.
Mafuta odzola nawonso ndi mpweya wa mpweya kwa chilengedwe, pogwiritsa ntchito mafuta ochepa, tikhoza kuchepetsa mpweya wa mpweya, apa pali njira zowerengera ndalama ndi ndondomeko zoperekera malipoti za mpweya wowonjezera kutentha wamakampani aku China petrochemical.
Kuwerengera kosalunjika: onjezani mpweya wotulutsa mpweya wopangidwa ndi ulalo wakumtunda wopangira mafuta opaka mafuta ndi ulalo wakumunsi wamafuta opaka mafuta kuti mupeze mpweya wofanana ndi mafuta opaka osungidwa.
Kuwerengera kwachindunji: Mafuta opaka mpweya wamafuta, mafuta opaka mafuta Ophatikizidwa ngati "mafuta ena amafuta", mtengo wake wochepa wa calorific ndi 41.031GJ/t, zomwe zili ndi kaboni pagawo la calorific mtengo ndi 20.00X102tC/GJ, ndi kuchuluka kwamafuta a carbon oxidation ndi 98% .Potengera chiwongolero chowerengera ndalama za petrochemical, njira yowerengera ndalama ndi motere:
Mpweya wotulutsa mafuta opaka mafuta (tCO₂) = mtengo wochepa wa calorific (GJ/t) x wa carbon pa unit calorific value (tC/GJ) x mafuta a carbon oxidation rate (%) x ofananira nawo mafuta opangira mafuta (t) x 44 / 12
Mpweya wa kaboni wamafuta opaka mafuta umaphatikizapo ulalo wa kaboni wopangira ulalo ndi ulalo wa kaboni wamankhwala, pogwiritsa ntchito zida zosefera mafuta, titha kuchepetsa mafuta opaka mafuta ndikuchepetsa kutulutsa mpweya.
Toni iliyonse yamafuta opaka mafuta omwe amadyedwa amawonjezera matani 88.5 a carbon dioxide, Kampani ina yamafuta opangira mafuta idapulumutsa matani 280 amafuta opaka chaka chatha, malinga ndi lipotilo.
mafuta a carbon emission formula, pa tani "mafuta opaka" amawonjezera 88.5 toni ya CO2 amapulumutsa matani 24,768 a carbon dioxide
