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.

1. Teknụzụ tozuru okè na ntụkwasị obi, arụmọrụ denitration dị elu na ibelata mgbapụ amonia.
2. Ngwa ngwa mmeghachi omume ọsọ.
3. Uniform amonia injection, obere nguzogide, obere amonia oriri na ọnụ ala ọrụ dị ala.
4. Enwere ike itinye ya na denitration na ala, ọkara na elu okpomọkụ.

1. Àgwà ndị e ji emepụta ike ikuku gas:
Ọ bụ ike fosil dị ọcha.Ọkpụkpụ ike gas sitere n'okike nwere uru nke nrụpụta ike dị elu, mmetọ gburugburu ebe obibi dị ala, arụmọrụ kachasị elu na-arụ ọrụ na obere oge ihe owuwu.
2, Emission akara atụmatụ nke eke gas enyi na enyi ike na-amụba nkeji
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%.
