Iithagethi zokunciphisa ikhabhoni zifezekiswa ngokusebenzisa ioyile yokuthambisa encinci
Ukukhutshwa kwekharbon dioksidi kwihlabathi jikelele kufuneka kuncitshiswe ngeepesenti ezingama-45 ngo-2030 ukusuka kumanqanaba ka-2010, kwaye kufikelele kwi-net-zero ekhutshwayo ngo-2050.
Ngokwe-Intergovernmental Panel on Climate Change (IPCC), ukukhutshwa kwerhasi ye-greenhouse ngo-2004 yayingama-49 eebhiliyoni ze-t-CO2, eyahlulwe ngabantu behlabathi abayi-6.4 yeebhiliyoni zabantu, ifikelela kwi-7.66 t-CO2 ngomntu ngonyaka.Ubungakanani beegesi zegreenhouse ezinokufunxwa ngokwemvelo ngumhlaba kucingelwa ukuba yi-11.4 bhiliyoni ye-t-CO2.Ukwahlulwe ngabantu behlabathi ekuqikelelwa ukuba babezibhiliyoni eziyi-9.2 ngo-2050, oku kuthetha ukuba umhlaba unokufunxa ngokwendalo i-1.24 t-CO2 ngomntu ngamnye ngowama-2050.
Iithagethi zokukhutshwa kwe-CO2 ezimiselwe kwi-Eco Vision 2050 zisekelwe kwindlela yokunciphisa ukukhutshwa kwegesi ye-greenhouse ngomntu ngamnye ukuya kwinqanaba lokuba umhlaba unokufunxa ngokwendalo.Okujoliswe kuko ekufuneka kufikelelwe ngowama-2030 kumiselwe kusetyenziswa ukubuyisela umva ukusuka kwi-Eco Vision 2050. Inkqubo isendleleni yokuseka iSicwangciso seXesha eliPhakathi lokusiNgqongileyo sowama-2019 kusetyenziswa ukubuyisela umva koko kujoliswe kuko ekufuneka kufikelelwe ngowama-2030.
I-oyile yokuthambisa iphinda ikhuphe ikhabhoni yokusingqongileyo, ngokusebenzisa i-oyile encinci, sinokunciphisa ukukhutshwa kwekhabhoni, nazi iindlela zokubala zokubala kunye nezikhokelo zokunika ingxelo malunga nokukhutshwa kwegesi yobushushu bamashishini aseTshayina epetrochemical.
Ukubala okungathanga ngqo: yongeza ukukhutshwa kwekhabhoni eveliswa likhonkco elinyukayo lemveliso yeoli yokuthambisa kunye nekhonkco elisezantsi lonyango lweoyile yokuthambisa ukuze ufumane ukukhutshwa kwekhabhoni ehambelana neoyile yokuthambisa egciniweyo.
Ubalo oluthe ngqo: I-oyile yokuthambisa i-carbon content, i-oyile yokuthambisa Idityaniswe njenge "ezinye iimveliso zepetroleum", ixabiso layo eliphantsi le-calorific yi-41.031GJ / t, umxholo wekhabhoni ngeyunithi yexabiso le-calorific yi-20.00X102tC / GJ, kunye nesantya se-fuel carbon oxidation yi-98% .Ngokubhekiselele kwisikhokelo sobalo lwepetrochemical, ifomyula yobalo ithi ilandelayo:
Ukukhutshwa kweCarbon ye-oyile yokuthambisa (tCO₂) = ixabiso eliphantsi le-calorific (GJ/t) x umxholo wekhabhoni ngeyunithi yexabiso lekhalori (tC/GJ) x isantya se-fuel carbon oxidation (%) x ehambelana nokusetyenziswa kwe-oyile ekrwada ye-oyile yokuthambisa (t) x 44 / 12
Ukukhutshwa kwekhabhoni yeoli yokuthambisa kubandakanya ukukhutshwa kwekhabhoni yekhonkco yokuvelisa kunye nokukhutshwa kwekhabhoni yekhonkco yonyango, ngokusebenzisa izixhobo zokucoca ioli, sinokunciphisa ioli yokuthambisa kunye nokunciphisa ukukhutshwa kwekhabhoni.
Itoni nganye yeoyile yokuthambisa esetyenzisiweyo yongeza iitoni ezingama-88.5 zekharbon diokside, Enye inkampani yepetrochemical isindise malunga neetoni ezingama-280 zeoyile yokuthambisa kunyaka ophelileyo, ngokwengxelo.
Ifomula yokukhutshwa kwekhabhoni yeoli, ngetoni nganye "ioli yokuthambisa" yonyusa i-88.5 itoni ye-CO2 yonga iitoni ezingama-24,768 zecarbon dioxide
