Hobane lipatlisiso mabapi le mokhoa oa ho thunya oa sebōpi sa samente li ntse li le boemong bo batlang bo pharaletseng, ho ntse ho e-na le mefokolo e mengata ea maemo a sebetsang ka har'a sebōpi le mokhoa oa ho etsa li-oxide tsa nitrogen indastering ea samente ea lehae.Ho na le mehloli e mengata ea nitrogen oxides le lintho tse ngata tse susumetsang.Lefapheng la thekenoloji ea ho fokotsa tlhahiso ea nitrogen oxide, mahlale a mantlha a teng a kenyelletsa SCR, SNCR, ho chesa ka mekhahlelo joalo-joalo.
Theknoloji ea phokotso ea SCR e khethang ke eona e ka sehloohong ea theknoloji lefatšeng.Ka ammonia kapa urea e le denitration absorption le catalytic selective absorption tlas'a ts'ebetso ea catalyst tower ea ho monya, sekhahla sa denitration se ka fihla ho feta 90%.
Theknoloji ea SNCR e sebelisa sebaka se loketseng sa mocheso (900 ℃ ~ 1100 ℃) seboping sa ho bola ho kenya motsoako oa ammonia ho sona.Ka mocheso ona, ammonia (NH3) e sebetsana le NOx ka khase ea flue ho hlahisa N2 le H2O.Sekhahla sa denitration ka kakaretso ke 40% - 60%, tšebeliso ea ammonia e kholo, 'me sekhahla sa ho phonyoha sa NH3 se phahame, se ka bang makhetlo a fetang 3 a SCR.
Hajoale, likhoebo tsa lehae tsa samente li se li qetile kaho ea SNCR denitration.Theknoloji ena e sebelisa ammonia e ngata e le moemeli ea fokotsang NOx.Ammonia e dutla habonolo nakong ea tlhahiso, lipalangoang, polokelo le tšebeliso, e bakang tšilafalo e tebileng tikolohong ea sepakapaka.
Ka hona, indasteri ea hajoale ea samente e hlile e tobane le bothata bo batlang bo hanyetsana.Tšebeliso ea ammonia denitration e ka fokotsa tlhahiso ea nitrogen oxide, empa bothata ba "ammonia escape" bo thata ho bo rarolla.Ho feta moo, tlhahiso ea ammonia ka boeona ke mokhoa oa ho sebelisa matla a mangata le tšilafalo e phahameng, 'me lipalangoang, polokelo le tšebeliso li tla boela li bake "ammonia phonyoha".
Ho ipapisitsoe le mathata a joalo, likhoebo tsa samente li lokela ho matlafatsa taolo ea lipalangoang le polokelo ea ammonia, ho ntlafatsa ts'ebeliso e ntle ea ammonia le ho fokotsa "ammonia phonyoho".
