Ruwan nitrogen mai ruwa, tare da dabarar sinadarai ta N₂, ruwa ne mara launi, mara wari, kuma mara guba wanda ake samu ta hanyar shan nitrogen ta hanyar sanyaya mai zurfi. Ana amfani da shi sosai a binciken kimiyya, magani, masana'antu, da daskarewar abinci saboda ƙarancin zafinsa da aikace-aikacensa daban-daban. To, ta yaya ake samar da ruwan nitrogen mai ruwa? Wannan labarin zai samar da cikakken amsa ga wannan tambaya daga fannoni da dama: fitar da nitrogen, hanyar rabuwar iska mai zurfi, tsarin samar da ruwa nitrogen, da aikace-aikacensa na aiki.

Fitar da sinadarin nitrogen

Samar da sinadarin nitrogen mai ruwa yana buƙatar matakin farko na samun sinadarin nitrogen mai tsarki. Nitrogen shine babban ɓangaren yanayin duniya, wanda ya kai kashi 78% na yawan iska. Ana fitar da sinadarin nitrogen yawanci ta amfani da fasahar rabuwar iska mai sanyi ko hanyoyin shaƙar iska mai matsin lamba (PSA). Raba iska mai sanyi mai zurfi ita ce hanyar da aka fi amfani da ita a masana'antu. Ta hanyar matsewa da sanyaya iska, yana raba iskar oxygen, nitrogen, da sauran abubuwan iskar gas a yanayin zafi daban-daban. Hanyar shaƙar iska mai matsin lamba tana amfani da kaddarorin shaƙar iska daban-daban na masu shaƙar iska daban-daban, suna cimma sinadarin nitrogen mai tsarki ta hanyar zagayowar shaƙar iska da shaƙar iska. Waɗannan hanyoyin suna tabbatar da tsarki da ingancin sinadarin nitrogen a matsayin kayan aiki na samar da sinadarin nitrogen mai ruwa.

Hanyar rabuwa da iska mai sanyi mai zurfi

Hanyar raba iska mai sanyi mai zurfi tana ɗaya daga cikin manyan matakai wajen samar da sinadarin nitrogen mai ruwa-ruwa. Wannan hanyar tana amfani da maɓuɓɓugan tafasa daban-daban na iskar gas a cikin iska don fitar da sinadarin nitrogen, iskar oxygen, da sauran abubuwan iskar gas a hankali. Tafasar sinadarin nitrogen shine -195.8℃, yayin da iskar oxygen take -183℃. Ta hanyar rage zafin jiki a hankali, ana fara fitar da iskar oxygen sannan a raba shi da sauran iskar gas, wanda hakan ke barin sauran sinadarin nitrogen mai tsarki. Daga baya, ana ƙara sanyaya wannan sinadarin nitrogen a ƙasan wurin tafasa don a zuba shi cikin ruwa-ruwa, wanda shine babban ƙa'idar samuwar sinadarin nitrogen mai ruwa-ruwa.

Tsarin samar da sinadarin nitrogen mai ruwa-ruwa

Tsarin samar da sinadarin nitrogen mai ruwa ya ƙunshi manyan matakai da dama: Na farko, ana matse iskar kuma ana tsarkake ta don cire ƙazanta kamar ruwa da carbon dioxide; sannan, ana sanyaya iskar kafin ta fara, yawanci zuwa kusan -100℃ don inganta ingancin rabuwar; na gaba, ana yin rabuwar sanyi mai zurfi, a hankali ana sanyaya iskar zuwa zafin sinadarin nitrogen mai ruwa don samun iskar nitrogen mai ruwa. A cikin wannan tsari, masu musayar zafi da hasumiyoyin rarrabawa suna taka muhimmiyar rawa wajen tabbatar da rabuwar sassa daban-daban a yanayin zafi mai dacewa. A ƙarshe, ana adana iskar nitrogen mai ruwa a cikin kwantena na musamman da aka tsara don kiyaye yanayin zafi mai ƙarancin yawa da kuma hana asarar tururi.

Kalubalen fasaha a cikin samuwar ruwa nitrogen

Samar da sinadarin nitrogen mai ruwa yana buƙatar shawo kan ƙalubale da dama na fasaha. Na farko shine kula da yanayin zafi mai ƙarancin zafi, domin wurin tafasar sinadarin nitrogen mai ruwa yana da ƙarancin zafi sosai. A lokacin aikin shaye-shaye, ya zama dole a kiyaye zafin da bai wuce -195.8℃ ba, wanda ke buƙatar kayan sanyaya da kayan kariya masu inganci. Na biyu, a lokacin aikin sanyi mai zurfi, dole ne a guji yawan danshi na iskar oxygen saboda iskar oxygen mai ruwa yana da ƙarfin sinadarin oxidizing kuma yana iya haifar da haɗarin aminci. Saboda haka, a lokacin aikin ƙira, dole ne a sarrafa tsarin raba sinadarin nitrogen-oxygen daidai, kuma dole ne a yi amfani da kayan da suka dace don tabbatar da aminci da kwanciyar hankali na tsarin. Bugu da ƙari, jigilar da adana sinadarin nitrogen mai ruwa yana buƙatar kwalaben Dewar da aka tsara musamman don hana hauhawar zafin jiki da asarar tururin nitrogen mai ruwa.

Ainihin aikace-aikacen ruwa nitrogen

Halayen ƙarancin zafin jiki na ruwa nitrogen sun sa ya zama mai amfani sosai a fannoni daban-daban. A fannin magani, ana amfani da ruwa nitrogen a fannin cryosurgery da kuma kiyaye nama, kamar daskarewar raunukan fata da kuma adana samfuran halittu. A fannin abinci, ana amfani da ruwa nitrogen don daskarewa abinci cikin sauri, saboda yanayin zafinsa mai ƙarancin zafi zai iya daskare abinci cikin sauri, yana rage lalacewar tsarin tantanin halitta kuma don haka yana kiyaye dandano da abinci na asali. A fannin bincike, ruwa nitrogen ana amfani da shi sosai a binciken superconductivity, gwaje-gwajen kimiyyar lissafi mai ƙarancin zafi, da sauransu, yana samar da yanayi na gwaji mai ƙarancin zafin jiki. Bugu da ƙari, a masana'antu, ana amfani da ruwa nitrogen a sarrafa ƙarfe, maganin zafi, da kuma iskar gas mara aiki don hana wasu halayen sinadarai faruwa. Kammalawa

Tsarin samar da sinadarin nitrogen mai ruwa tsari ne mai sarkakiya, wanda galibi ake samu ta hanyar hanyoyin raba iska mai sanyi da fasahar shaye-shaye. Ƙarfin sinadarin nitrogen mai ƙarancin zafin jiki yana sa ya taka muhimmiyar rawa a fannoni daban-daban kamar masana'antu, magunguna, da bincike. Daga fitar da iskar nitrogen zuwa shaye-shaye mai sanyi mai zurfi da kuma a ƙarshe zuwa aikace-aikacensa, kowane mataki yana nuna ƙarfin fasahar sanyaya da rabuwa mai zurfi. A cikin ayyukan aiki, masu fasaha suna buƙatar ci gaba da inganta tsarin samarwa don rage amfani da makamashi da inganta ingancin samar da sinadarin nitrogen mai ruwa.

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