Ungayithola kanjani igesi ephezulu yokuhlanza i-nitrogen kusuka emoyeni?
1. Indlela yokuhlukaniswa komoya ye-Cryogenic
Indlela yokwehlukanisa kwe-Cryogenic idlulele eminyakeni engaphezu kwengu-100 yentuthuko, futhi iye yabhekana nezinqubo ezahlukahlukene ezahlukahlukene ezifana namandla kagesi aphezulu, aphezulu kanye nengcindezelo ephansi, nenqubo ephansi ye-voltage. Ngokuthuthukiswa kobuchwepheshe besimanje somoya kanye nemishini, inqubo yokuvela okuphezulu, okuphezulu nokuphansi kwengcindezi, kanye ne-vacuum ephakathi nendawo kuqedwe ngokuyisisekelo. Inqubo ephansi ephansi - ephansi yokusebenzisa amandla aphansi kanye nokukhiqizwa okuphephile sekuyisinqumo sokuqala samadivayisi we-vacuum amakhulu aphakathi nendawo. Inqubo ephelele yomoya ephansi yomoya ihlukaniswe ngezinqubo zokucindezela kwangaphandle kanye nezinqubo zangaphakathi zokucindezela ngokuya ngezixhumanisi ezahlukahlukene zokucindezela komoya-mpilo nemikhiqizo ye-nitrogen. Inqubo ephelele yokucindezela okuphansi-okucindezelayo ikhiqiza i-oksijini ephansi noma i-nitrogen, bese icindezela igesi yomkhiqizo kwingcindezi edingekayo yokunikeza umsebenzisi nge-compressor yangaphandle. Ingcindezi egcwele kwinqubo ephansi yokucindezela i-oksijini noma i-nitrogen ewuketshezi ekhiqizwa yi-distillation ehlanekezelwe yamukelwa ngamaphampu afakwe ku-uketshezi ebhokisini elibandayo ukuholwa ngumsebenzisi, futhi umsebenzisi uhlinzekwa ngemuva kwensiza enkulu yokushintshanisa. Izinqubo eziphambili zihlunga, ukucindezela, ukupholisa, ukudilizwa, i-supercharger, ukwanda, ukukhishwa, ukuhlukaniswa, ukuhlukaniswa, ukuhlukaniswa, ukuhlukaniswa komoya ovundwayo.
2. Ingcindezi Swing Adsorption Methoft (Indlela PPA)
Le ndlela isuselwa emoyeni ocindezelwe njengento eluhlaza. Ngokuvamile, ukuhlolwa kwama-molecular kusetshenziswa njenge-adsorbent. Ngaphansi kwengcindezi ethile, umehluko wokutholwa komoya-mpilo kanye nama-molecule we-nitrogen emoyeni emasondweni ahlukene ama-molefanelar asetshenziswa. Eqoqweni legesi, ukwahlukaniswa komoya-mpilo kanye ne-nitrogen kuyaqaliswa; Futhi i-ejenti yokuthola amamolekhuya ahlaziya futhi yaphinde yavuselela kabusha ngemuva kokususwa kwengcindezi.
Ngaphezu kwama-molecular sievs, ama-adsorbents angafaka futhi i-alumina ne-silicone.
Njengamanje, i-adsogen yokwenza ama-adsogen ye-adsogen ye-adsogen ye-adsogen esetshenziswa kakhulu isuselwa emoyeni ocindezelwe, isihluthulelo se-carbon molecular njenge-adsorpent, futhi isebenzisa umehluko kumandla we-adsorption kanye ne-nitrogen kunezimpawu ezihlukile ze-adhorption ukufezekisa i-oksijini kanye nokuhlukaniswa kwe-nitrogen. Okokuqala, umoya-mpilo osemoyeni ubeka phambili ama-molecule e-carbon, anothisa i-nitrogen esigabeni segesi. Ukuze kutholakale i-nitrogen ngokuqhubekayo, kudingeka umbhoshongo owodwa we-adsorption.
Isicelo
1. Izici zamakhemikhali ze-nitrogen zizinzile kakhulu futhi ngokuvamile aziphenduli kwezinye izinto. Le khwalithi yangephakathi ivumela ukuthi isetshenziswe kabanzi ezindaweni eziningi ze-anaerobic, njengokusebenzisa i-nitrogen ukufaka umoya esitsheni esithile, esidlala indima ekuhlukanisweni, okuqhuma kabusha, kanye ne-anticorrosion. I-LPG Engineering, amapayipi egesi kanye namanethiwekhi we-bronchial we-bronchial asetshenziswa ekusetshenzisweni kwezimboni kanye nokusetshenziswa kwezempi [11]. I-nitrogen nayo ingasetjenziselwa ekuphaketheni kokudla okusetshenzwe nemithi njengoba isembozo, izintambo zokubopha, imigqa yocingo, kanye namathayi enjoloba acindezelwe angakhula. Njengohlobo lokulondolozwa, i-nitrogen imvamisa ithathelwa indawo ngaphansi komhlaba ukuze yehlise ukugcwala okukhiqizwe ukuxhumana phakathi kwekholomu yeshubhu kanye ne-stratum fluid.
2. I-Nitrogen ephezulu ye-Nitrogen isetshenziswa kwinqubo yokuncibilika yensimbi yokuncibilika ukuze ihlanzele insimbi incibilike ukuze ithuthukise ikhwalithi yokuphonsa kungenalutho. Igesi, ivimbela ngempumelelo i-opidation ephezulu kakhulu yamazinga okushisa ethusi, igcina ingaphezulu kwezinto zethusi, futhi liqede inqubo yokukhulisa. I-nitrogen -based -based yamalahle igesi (ukwakheka kwayo yile: 64.1% N2, 34.7% H2 kanye nenani elincane le-CO2) njengegesi elivikelayo ngesikhathi sokuncibilika kwe-Copper, ukuze i-Copper incibiliza ikhwalithi yomkhiqizo.
I-3. Cishe i-10% ye-nitrogen ekhiqizwa njengesiqandisi, ikakhulukazi ifaka phakathi ukuqina okuthambile noma njengokuqina okufana nerabha, ukufakwa okubandayo, kanye nokufakwa kwegazi, kanye nokugcinwa kwegazi kwegazi kupholile kwezokuhamba.
I-4. I-Nitrogen ingasetshenziswa ukuhlanganisa i-nitric oxide noma i-nitrogen dioxide ukudala i-nitric acid. Le ndlela yokukhiqiza iphakeme futhi intengo iphansi. Ngaphezu kwalokho, i-nitrogen nayo ingasetshenziselwa i-ammonia yensimbi ye-nitride.
