Liquid nitrogen da ruwa oxygen ruwa ne guda biyu da ake amfani da su a cikin masana'antu da bincike. Kowannensu yana da nasa aikace-aikace masu fadi da kuma na musamman. Dukansu ana samar da su ta hanyar rabuwar iska, amma saboda nau'ikan sinadarai da kaddarorinsu na zahiri, suna da halaye daban-daban a aikace. Wannan labarin zai bincika takamaiman aikace-aikacen nitrogen na ruwa da oxygen ruwa da bambance-bambancen su.

I. Aikace-aikace na Liquid Nitrogen

Ana samun sinadarin nitrogen ta hanyar sanyaya iska zuwa ƙasa da wurin tafasar nitrogen. Babban bangarensa shine iskar nitrogen (N₂). Ƙarƙashin ƙarancin zafin jiki na nitrogen na ruwa ya sa ya zama mai amfani sosai, musamman ya haɗa da abubuwa masu zuwa:

Daskarewar ƙarancin zafin jiki da adanawa

Ɗaya daga cikin abubuwan da aka fi amfani da ita na ruwa nitrogen shine don daskarewa mai zafi da kuma adanawa, musamman a fannin biomedicine. Yanayin zafin jiki na nitrogen mai ruwa yana da ƙasa da -196 ° C, wanda zai iya daskare kyallen takarda, sel, da embryo da sauri da adana su na dogon lokaci, yana tabbatar da ayyukansu. Waɗannan aikace-aikacen suna da mahimmanci a cikin binciken likita, dashen gabobin jiki, da kiwo na gwaji.

Daskarewa abinci

A cikin filin sarrafa abinci, ana amfani da ruwa nitrogen don daskare abinci cikin sauri, kamar abincin teku, nama, da 'ya'yan itatuwa. Daskarewar ruwa na nitrogen na iya rage zafin abinci cikin sauri, ta haka rage samuwar lu'ulu'u na kankara da kare dandano da darajar abinci.

Sanyaya da firiji

Hakanan ana amfani da nitrogen mai ruwa don sanyaya da sarrafa zafin kayan aikin inji. Misali, ana iya amfani da nitrogen mai ruwa azaman matsakaicin sanyaya don rage juzu'i da zafi a cikin sarrafa injin, don haka inganta daidaiton aiki da inganci.

Aikace-aikace na nitrogen gaseous: Liquid nitrogen kuma zai iya samar da iskar nitrogen mai tsafta bayan tururi, wanda ake amfani da shi sosai a masana'antar sinadarai a matsayin iskar kariya don hana haɓakar iskar oxygen na abubuwa masu cutarwa.

II. Aikace-aikace na Liquid Oxygen

Babban bangaren ruwa oxygen shine oxygen (O₂), wanda kuma ana samun shi ta hanyar fasahar rabuwa mai zurfi ta cryogenic. Oxygen, a matsayin muhimmin kashi don tallafawa rayuwa da halayen sinadarai, yana da aikace-aikace daban-daban, galibi ana nunawa a cikin waɗannan fannoni:

Medical oxygen wadata

Ana amfani da iskar oxygen mai ruwa sosai a asibitoci da kulawar gaggawa, yana ba da isasshen iskar oxygen ga marasa lafiya don taimakawa numfashi. Musamman a cikin maganin cututtuka na numfashi, samar da iskar oxygen yana da mahimmanci. Oxygen ruwa yana da ƙananan ƙarami, tare da babban abun ciki na oxygen, dacewa don ajiya da sufuri, kuma yana daya daga cikin nau'o'in da aka fi so na samar da iskar oxygen.

Masana'antu oxidant

Ana yawan amfani da iskar oxygen mai ruwa a matsayin oxidant a masana'antu, musamman a cikin narkewar karfe da samar da sinadarai. Ana iya amfani da iskar oxygen mai ruwa don taimakawa konewa, ƙara yawan zafin konewa da ingancin amsawa. Misali, a tsarin yin karfe, ana allurar iskar oxygen a cikin ruwan narkakkar karfe don cire datti da kuma inganta tsaftar karfe.

Aerospace da makaman roka

Liquid oxygen man fetur ne da aka saba amfani da shi a cikin tsarin tukin roka, gauraye da mai mai ruwa (kamar ruwa hydrogen) don konewa, yana samar da makamashi mai yawa don tura rokoki zuwa sararin samaniya. Kyawawan kaddarorinsa na konewa na taimaka wa ruwa oxygen ya zama abin da ba dole ba ne a cikin masana'antar sararin samaniya.

III. Bambance-bambance tsakanin Liquid Nitrogen da Liquid Oxygen

Kodayake aikace-aikacen nitrogen na ruwa da oxygen na ruwa sun bambanta, suna da bambance-bambance masu mahimmanci a yanayi da amfani. Musamman:

1. Abun da ke ciki: Liquid nitrogen yana ɗauke da iskar nitrogen (N₂), yayin da ruwa oxygen ya ƙunshi iskar oxygen (O₂).

2. Density: Liquid nitrogen ne mafi yawa fiye da ruwa oxygen.

3. Wurin tafasawa: Liquid nitrogen yana da ƙarancin tafasawa fiye da ruwa oxygen.

4. Amfani: Ana amfani da nitrogen mai ruwa don daskarewa da adanawa, yayin da ake amfani da iskar oxygen mafi yawa azaman oxidant da propellant. Abubuwan sinadaran

Nitrogen ruwa a zahiri ba shi da ƙarfi, tare da ingantaccen tsarin kwayoyin halitta wanda ke sa ba zai yuwu a sami halayen sinadarai tare da wasu abubuwa ba. Wannan dukiya ta ba da damar yin amfani da shi azaman iskar gas mai kariya kuma ana amfani da shi a yawancin hanyoyin sinadarai da masana'antu. A daya hannun, ruwa oxygen ne mai karfi oxidizer tare da high sinadaran reactivity, kuma shi ne mai yiwuwa ga tsanani hadawan abu da iskar shaka halayen tare da sauran abubuwa, sa shi yadu amfani a konewa da hadawan abu da iskar shaka tafiyar matakai.

Halayen zafin jiki

Wurin tafasar nitrogen na ruwa ya yi ƙasa da na ruwa oxygen (ruwa nitrogen -196 ° C, ruwa oxygen -183 ° C), sa ya dace da sanyaya da kuma kiyayewa a ƙananan yanayin zafi. Ko da yake ruwa oxygen shima yana cikin nau'in ruwa na cryogenic, ƙarancin zafinsa bai kai na ruwa nitrogen ba. Sabili da haka, ana amfani da iskar oxygen mai ruwa don konewa da oxidation maimakon adanar cryogenic. Tsaro

Nitrogen ruwa yana da ingantacciyar lafiya don amfani saboda ba shi da kusanci ga halayen sinadarai. Babban haɗari shine raunin sanyi daga ƙananan zafin jiki da kuma maye gurbin oxygen a cikin sararin samaniya, wanda zai iya haifar da asphyxiation. Yayin da ruwa oxygen, a matsayin oxidizer, dole ne a kiyaye shi daga abubuwa masu ƙonewa kamar mai don hana konewa da haɗarin fashewa. Saboda haka, yana buƙatar ƙarin taka tsantsan yayin amfani.

Nitrogen ruwa da oxygen ruwa sune mahimman ruwa masu ƙarancin zafin jiki guda biyu. Duk da cewa an samar da su ta hanyar rabuwar iska, saboda nau'ikan sinadarai da kayan aikinsu daban-daban, filayen aikace-aikacen su suna da mabambantan mayar da hankali. Liquid nitrogen, tare da inertness da low-zazzabi halaye, da aka yadu amfani a daskarewa adana, abinci aiki, da kuma masana'antu sanyaya, da dai sauransu Yayin da ruwa oxygen, dogara a kan ta oxidizing Properties, da aka yafi amfani da likita oxygen wadata, masana'antu hadawan abu da iskar shaka, da kuma Aerospace propulsion, da dai sauransu A m ayyuka, da yin amfani da ruwa da ruwa oxygen na bukatar cikakken inganci da aikace-aikace na su nitrogen.

Mu masana'anta ne kuma masu fitar da na'urar rabuwar iska. Idan kuna son ƙarin sani game da mu:
