Maganin sharar iskar gas na samar da wutar lantarki
Gabatarwar fasaha
Samar da wutar lantarki na iskar gas yana nufin samar da wutar lantarki ta hanyar iskar gas mai yawa (LFG landfill gas) da ake samu ta hanyar anaerobic fermentation na kwayoyin halitta a cikin sharar gida, wanda ba wai kawai yana rage gurbacewar iska ta hanyar konewar sharar gida ba, har ma yana yin amfani da albarkatu mai inganci.
Saboda fitar da iskar nitrogen oxides a cikin aikin samar da wutar lantarki na bukatar biyan bukatun sashen kare muhalli, ana bukatar a yi maganinsa kafin a iya fitar da shi cikin yanayi.

A cikin cakuda iskar gas ɗin da na'urar samar da iskar gas ke fitarwa.Abubuwan da ke cutarwa galibi oxides NOX ne.Nitrogen oxides masu guba ne, iskar gas mai ban haushi tare da illa ga lafiya da muhalli.
Nitrogen oxide NOx yafi ƙunshi nitric oxide NO da nitrogen dioxide NO2.Bayan an fitar da sinadarin nitric oxide a cikin sararin samaniya, ta hanyar sinadarai tana amsawa tare da iskar oxygen a cikin iska kuma an sanya shi oxidized zuwa nitrogen dioxide NO2.
Maganin iskar iskar gas na injin janareta na iskar gas galibi yana nufin maganin nitrogen oxides NOx.
A halin yanzu, ana gane fasaha ta SCR a matsayin babbar fasaha don cire nitrogen oxides NOx.Fasahar hana fasa kwaurin SCR tana da kason kasuwa kusan kashi 70% a duniya.A kasar Sin, wannan adadi ya zarce kashi 95%.
