Ọgwụgwọ gas na-ekpofu ọkụ nke ike ọkụ gas
Nkà okwu mmeghe
Ọgbọ ike ikuku nke ala na-ezo aka n'ọgbọ ike site na nnukwu gas biogas (LFG landfill gas) nke anaerobic fermentation nke ihe ndị dị ndụ na-emepụta n'ime ala, nke na-abụghị nanị na-ebelata mmetọ ikuku nke ọkụ n'efu na-akpata, ma na-ejikwa ihe onwunwe eme ihe nke ọma.
N'ihi na mwepụta nke nitrogen oxides na usoro nke nrụpụta ike ikuku gas kwesịrị imezu ihe achọrọ nke ngalaba nchedo gburugburu ebe obibi, ọ dị mkpa ka a gwọọ ya tupu enwee ike ịpụ ya na ikuku.

N'ime ngwakọta gas na-emepụta site na nrụpụta gas na-emepụta ihe.Ihe ndị na-emerụ ahụ bụ oxides NOX.Nitrogen oxides bụ gas na-egbu egbu, na-akpasu iwe nwere mmetụta na-emebi ahụike na gburugburu ebe obibi.
Nitrogen oxide NOx kacha nwere nitric oxide NO na nitrogen dioxide NO2.Mgbe nitric oxide ga-esi banye n'ikuku, ọ na-emeghachi omume na oxygen na ikuku ma mee ka ọ bụrụ nitrogen dioxide NO2.
Ngwọta ikuku iyuzucha nke ihe na-emepụta gas sitere n'okike na-ezo aka na ọgwụgwọ nke nitrogen oxides NOx.
Ka ọ dị ugbu a, a na-amata nkà na ụzụ denitration SCR dị ka teknụzụ tozuru oke maka iwepu nitrogen oxides NOx.Nkà na ụzụ denitration SCR nwere oke ahịa ihe fọrọ nke nta ka ọ bụrụ 70% n'ụwa.Na China, ọnụ ọgụgụ a agafeela 95%.
