SCR vs SNCR: Zaƙi Tarihin Kusantarwa da Ake So Don Sana'ah

Shiryar: Fasahar Na Siffa Na Teknologiya Na Karamin NOx

Samunin Na Nitrogen oxides (NOx) suna ne daga cikin abubuwan da suka yi kusurin na yankin gida don samunin da suke amfani da prosesin na kusurin. Samunin na kudin, faburin na sementi, faburin na steel, samunin na wata da kimiyya suna samunin NOx a lokacin kusurin na yawa.

Don samunin tsarin samunin da suka zama yawa da yawa, shirkokan su need da teknologiyar denitrification na flue gas da ke kira. A cikin mahaillan na teknikai na karamin NOx, Selective Catalytic Reduction (SCR) da Selective Non-Catalytic Reduction (SNCR) suna ne daga cikin waɗanda suka yi amfani da su a yawa.

Wadannan biyu teknolujin suka yi amfani da ammonia-based reducing agents don yin NOx zuwa nitrogen da ruwa wanda ba shi da dama. Amma, suna da farko mai mahimmanci a matsayin mechanism na reaction, temperature na aiki, efficiency na karewa, abu ne da ke cikin bayani, da kuma lokacin da aka yi amfani da su.

Za a zahiri wani daga cikin SCR ko SNCR tare da matakalar da suka fuskanta, kamar: alamun da suka bayani, yadda suka yi amfani da flue gas, ƙananan wuri da ke cikin gida, da kuma bayani na project.

Kamar wani masu amfani da teknolujin na tsari, MirShine Environmental Group ya ba solushin na SCR da SNCR wanda aka saita don hanyar da suka yi amfani da su a cikin industriya, don tabbatar da yadda suka yi amfani da NOx a cikin wayo mai kyau.

Wani ne SCR Technology?

SCR (Selective Catalytic Reduction) shine teknolujin mai kyau na denitrification wanda suka yi amfani da catalysts don yin chemical reaction na ammonia da nitrogen oxides mai kyau.

A cikin sistan SCR, ammonia ko ƙwalla na ammonia an taimaka shi cikin gas na kofa ta hanyar sistan taimakawa na ammonia. Gas mai tsaya yayi gudun cikin reactor na katalis, inda NOx an raba shi zuwa nitrogen da ruwa.

Muhimmancin rashin kimya shi ne:

NOx + NH₃ → N₂ + H₂O

Katalis yana ba da imkanin wannan rashin ya zama mafi kyau a wani yadda mai ƙarami na yamma.

Sistansu na SCR suna amfani da su a yankuna masu amfani da abubuwa masu yawa wanda suka bukata mafi kyau na karewa na NOx da tsayayen mafi kyau na lokacin daga cikin lokaci.

Ayyukan da ke ƙarƙashin su suni:

• Mashefin kudaden kwalli
• Turbinin gas
• Shuka-shara-zuwa-Makamashi
• Tashar shanu
• Tattalin kimiyya na petroli
• Bulurin masu yawa na industriya

Wane ne teknolujin SNCR?

SNCR (Rabawa Ba Tare da Katalis Ba Zai Iyaka) shi ne teknolujin na karewa na NOx wanda ba a bukata katalis don amfani da ita.

A wata, ammonia ko urea solution zai shigar da kwayar yin gaba na sautin yin gaba ta amma. A cikin tsawon yin gaba daidai, abu na sautin yin gaba zai yi amma da NOx kuma zai sanya shi a noma da ruwa.

Tsawon yin gaba na SNCR shine kamar yadda ya dace da SCR, kamar yadda ya dace da 850–1100℃.

Don haka, SNCR ba za su bukatar catalysts mara kyau ko reactors mai tsawo, don haka shine kamar yadda ya dace da SCR a matsayin bukatun kasa.

SNCR ana amfani da shi a al'adu da ke ciki da:

• Fasaha ita ce karami
• Sautin yin gaba na NOx ita ce daidai
• Bukatun kasa ita ce karami

Ayyukan da ke ƙarƙashin su suni:

• Cement kilns
• Waste incinerators
• Industrial furnaces
• Tashin fadawa na lime

SCR vs SNCR: Farkakken Sannu

Idan kadan kuma suna gudan cikin yadda suka ci gaba da NOx ta hanyar amfanin da ke taka, kuma yadda suka yi aiki da suka dace ba su daidai.

1. Yadda ake bukata catalyst

Farko muna kafin SCR da SNCR shine yadda ake bukata catalyst ko ba.

SCR:

• Ya amfani da catalyst modules
• Ya ba da karamin yadda ake gudan cikin yadda suka ci gaba
• Ya bukata gudan cikin catalyst da sauya

SNCR:

• Ba sa amfani da catalyst
• Yana da tsarin abin da ke ƙasa
• Ya bukata kontroli na yadda za a sanya ƙarfi

Catalyst a cikin SCR ya kara tsarin aiki kuma ya ba mu imkanin kare NOx a yadda mai ƙarfi.

2. Karamin kare NOx

Karamin ita ce babu wani abu da ke maimakon yadda za a ziyarci teknikolin kare nitrates.

SCR yana da shirin:

• karamin kare NOx daga 80 zuwa 95%

SNCR yana da shirin:

• karamin kare NOx daga 30 zuwa 70%

Don kuma, lokacin da yawa da kari na gaso suka buƙata, SCR shine ya zama amsa ta fito.

Ga wasu al’ummar da ke ciki da kari na gaso ta yawa, SCR ta ba da ƙarfi na yawa.

3. Kari na ƙarfi na yin amfani

Ƙarfi na yin amfani shine wani daga cikin farko na farko.

SCR ya zama aminci a cikin kari na:

300–420℃

SNCR ya buƙata ƙarfi na yin amfani mai ƙarfi:

850–1100℃

Idan wani ƙashe na gaba ce da kari na yin amfani ta yawa, SNCR za ta iya zama amsa ta fito. Amma idan kari na yin amfani ce da kari na yawa, SCR za ta iya zama ta fito.

4. Sabis na kudin amfani

Sabis na kudin amfani shine abin da ke ciki da muhimci ga wasu al’ummar.

SNCR ya zama aminci a cikin:

• Karamin kudin sauyi na kayan aikin
• Saukaro mai yawa
• Yawa kadan bukatun sauyi

SCR yana da mahimmanci:

• Kayan aikin reactor
• Kayan aikin catalyst
• Sistemin yin kafa ammonia
• Tashin inginiyarin yawa kadan daga cikin wani

Amma, SCR ya ba da kwayoyin yawa kadan da kuma kariya mai ƙarfi na kariya na gaba daya.

5. Kananan wani

Sisitem na SNCR suna bukata kananan wani na sauyi saboda suna ba da bukatun reactor na catalyst.

Sisiteman SCR suna buƙata ƙaramin yanki don:

• Sakamako na reactor
• Katalis kuma laye
• Tashin gas na flue

Don wasu ƙwarai na gaba da yankin da ke da yanki mai ƙarami, ake buƙata amfani da bayani na ingilishi kafin zaɓar SCR.

Jadde na fuskoka: SCR vs SNCR

Yaya za a zaho bayan SCR da SNCR?

Ba wani ƙarfi ne da ke da kyakkyawan yadda ake amfani da shi a cikin dukkanin kasuwanci na industriya.

Za a yi amfani da wasu abubuwa don zahon ƙarfin da ake so.

1. Yadda ake buƙatar gudanen wani abu

Yadda ake buƙatar NOx a cikin wani abu shine mafi muhimmin abu.

Idan wani abu ya nuna yadda ake buƙatar NOx da yawa, SCR shine mafi kyakkyawa.

Idan yadda ake buƙatar NOx da yawa ba suka nuna, SNCR zai iya samun abin da ake so.

2. Hali na gasin da ke ƙarƙashin kofin

Muhimmanci na bayanin ƙwararren yadda ake sauyawa suka kashe:

• Kari na yin flue gas
• Kudin NOx
• Kari na oxygen
• Karamin dust
• Kudin SO₂
• Yawan Ruwa a Cikin Na'ura

Duk wani ƙwararren yadda ake sauyawa yana da hali na gasin da ke ƙarƙashin kofin da ba daidai, don haka yana bukatar solusi mai gaba daya.

3. Hali na abubuwan da suka dace

Don wani ƙwararren yadda ake sauyawa da ke cikin wani ƙwararren yadda ake sauyawa, hali na abubuwan da suka dace shine muhimmanci.

Masu inganta suna bukata amfani da:

• Dabarun da aka kwatance don Shirya
• Tsarin boiler ko kiln
• Tashin gas na flue
• Sakon da ke cikin wani ƙwararren yadda ake sauyawa

4. Budjetin na Aikata da Kudin Samun Aiki

Kamar yadda SNCR ya ba shi kudi mai ƙarami, SCR zai iya ba da ala'adai mai kyau don zamanin daga baya.

Shugabannin shirye-shiryen suka yi amfani da:

• Sashe na farko
• Karamin yin kafa ammonia
• Sauran katalis
• Kudin Aiki na Gudunmawa
• Kura na kura na kura na kura

Amsa na SCR + SNCR

A cikin wasu ayyukan industriya, SCR da SNCR za su iya haɗawa don samun ala'adai mai kyau.

Misali:

SNCR zai iya amfani da shi don bayani na NOx a wani yanki mai ƙarfi na hanyar gaba, kuma SCR zai ba da bayani na NOx a wani yanki na gaba don sauran bayani.

Wannan haɗawa zai iya taimaka:

• Gudun samun ammonia
• Sanya yin aiki da kariya
• Sanya kudin haɗa

Amsa na gaba daya suna ƙarƙashin amfani a cikin al'adu na gaba daya na bayanai na sarakuna.

Amsa na MirShine don fuskanta

MirShine Environmental Group ta ba amsa mai kyau na bayanai na NOx, wanda suka kasance:

• Sistemu na SCR
• Sistemu na SNCR
• Amsa na SCR don sauya
• Sistemu na injekshin na ammonia
• Amsa na gaba daya na tattalin arziki na gas

Tumurin mu na inggiliya yana gudanin kowane aikin kamar haka:

• Istilin sana'a
• Karakatun gasin da suka fiye
• Budunin samun kuma
• Shugaban Zanen
• Gudunmawar abin da ya zama mabudin al'umma

Ta hanyar yin amfani da tushen inggiliya da teknologiyoyin sauyin biyutu, MirShine ta taimaka wajen samun kula da NOx da ke cikin sana'a ta hanyar mahallin da ke tsakanin kula da kula.

Kammalawa

Teknologiyoyin SCR da SNCR suna taka shirin muhimmin a cikin rarraba NOx a sana'a.

SNCR ta ba da aiki mai kyau da kuma mai ƙarfi don ayyukan da ke bukatar rarraba NOx da ke ƙarkara, amma SCR ta ba da kula mai kyau kuma ta fito don kofin fuskancin da ke ƙarkara.

Za a bukatar gudanin matakan aiki, koƙarin biyutu, da gudunmawar aiki na daga wani masu inggiliya don zahiri teknologiyar rarraba NOx.

Daga wani inggiliya mai ƙarfi da kuma taimakawa ta kowane aikin, MirShine ta ba da aiki mai kyau don SCR da SNCR ga sana'ayen duniya.
