I-Ammonia irhasi yotywala njani?
1. I-Ammonia irhasi yotywala njani?
Uxinzelelo oluphezulu: Ubushushu be Igesi yase-Ammonia ngu-132.4C, ngaphaya kwale nkunkuma ye-Ammonia igesi akukho lula kulwalo. Kodwa phantsi kweemeko eziphezulu zoxinzelelo, iAmmonia inokuba lotywala nakwiqondo lobushushu elingaphantsi kobushushu obukhulu. Phantsi kweemeko eziqhelekileyo, lo gama nje i-Amonia uxinzelelo lingaphezulu kwe-5.6MPA, linokutolikwa ngamanzi am amonia.
Iqondo lokushisa elisezantsi: xa kuthelekiswa nezinye iigesi, i-ammonia kulula ukuba yotywala. Esinye sezizathu eziphambili kukuba iqondo lobushushu le-ammonia liphantsi. Ke ngoko, igesi yaseAmmonia itywala ngokulula kakhulu kubushushu obuphantsi. Kwingcinezelo yemozulu esemgangathweni, indawo yokubila yeAmmonia imalunga nama-33.34 ° C, kwaye kobushushu, i-Ammonia sele ikwimeko yolwelo.
Emoyeni kwiqondo lokushisa eliphezulu, iimolekyuli zeAmmonia zidityaniswe ngokulula neemolekyuli zamanzi ukuze zikwazi ukwenza i-ammonia amanzi, engu-Ammomia igesi.
Ukuguquguquka: Isakhiwo se-Ammonia igesi ilula, amandla phakathi kweemolekyu asithobekile, kwaye igesi yaseAmmonia iguquguquka kakhulu. Ke ngoko, lo gama ubushushu kunye noxinzelelo lwegesi zihlise ngokwaneleyo, igesi yase-Ammonia inokuthathwa ngokulula.
2. Kutheni le-ammonia ilula kunomoya?
I-Ammonia incinci kunomoya. Ukuba isixokelelwane se-molecular se-molecular serhasi ethile siyaziwa, ngokobunzima bayo, ungagweba uxinano lwaso xa kuthelekiswa nomoya. I-avareji ye-molecular yesihlobo se-molecular ye-29. Bala ubunzima bayo bemolekyuli. Ukuba ingaphezulu kwe-29, ububi buyinto enkulu kunomoya, kwaye ukuba ungaphantsi kwe-29, ubungangamsha buncinci kunomoya.
3. Kwenzeka ntoni xa i-Amonia ishiywe emoyeni?
ukuqhuma kwenzeka. I-Ammonia Amanzi yirhasi engenamabala kunye ne-odor ecaphukisayo kwaye inyibilika ngokulula emanzini. Inokuqhuma xa umoya une-20% -25% ye-ammonia. Amanzi ammonia sisisombululo se-ammonia. Imveliso yemizi-mveliso ilulwelo olungenamibala kwaye lubonakale olubonakalayo kunye nephunga elinamandla nelitshisi.
4. Ingakanani i-amonia enetyhefu emoyeni?
Xa uxinzelelo lwe-ammonia emoyeni yi-67.2mg / m³, i-nasopharynx ivakala icaphukisiwe; Xa uxinzelelo luyi-175 ~ 300mg / M³, impumlo kunye namehlo kunye nama amehlo aphefumlelweyo ayakhawuleziswa; Xa uxinzelelo lufikelela kwi-350 ~ 700mg / m³, abasebenzi abanakusebenza; Xa uxinzelelo lufikelela kwi-1750 ~ 4000mg / m³, inokuba sisongela ubomi.
5. Luthini ukusetyenziswa kwegesi ye-ammonia?
1. Khuthaza ukukhula kwezityalo: I-Amonia ngumthombo obalulekileyo we-nitrogen ofunekayo ekukhuleni kwezityalo, ezinokuphucula ukuchuma komhlaba nokukhuthaza ukukhula kwezityalo nophuhliso lwezityalo.
I-2. Ukuveliswa kweechumisi zekhemikhali: I-Ammonia sisixhobo esibalulekileyo sokungabi semveliso ye-nitrogen. Emva kokuphendula kwekhemikhali, inokwenziwa i-Ammonia amanzi, urea, i-Ammonium nitrate kunye nezinye izichumisi.
3. Ifriji: I-Ammonia inezinto ezisebenzayo zefriji kwaye isetyenziswa ngokubanzi ekwenzeni iifriji, izixhobo zefriji kunye nezinye iinkalo.
4. Isicoci: Igesi yase-Ammonia inokusetyenziselwa ukucoca iglasi, indawo yensimbi, ikhitshi, njl njl.
6. Isityalo semveliso ye-ammonian sivelisa njani i-ammonia?
1. Imveliso ye-ammonia yindlela ye haber:
I-N2 (G) + 3h2 (g) ⇌2nh3 (g) △ rhθ = -92.4kj / Mol (iimeko zokuphendula zinobushushu obuphezulu, uxinzelelo oluphezulu, i-catalyst)
I-2. I-Amonia Imveliso yeGalo yeNdalo: Irhasi yendalo isuswe kuqala, emva koko iguqukele kwinguqu yesibini, emva koko iqulethe i-0.1% ye-Itrogen ye-Carbon, i-carbon diokside (i-carbon diokside (i-birbon dioxide (igesi ecocekileyo ene-a I-Hydrogen-to-nitrogen ye-Hydrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen ye-Hydrogen-to-nitrogen Inkqubo ye-Ammonia ye-Ammonia isebenzisa i-naphtha njengento engafunekiyo ifana nale nkqubo.
3. Ukuveliswa kwe-ammonia kwioyile enzima: Ioyile enzima ibandakanya ioyile yentsalela efunyenwe kwiinkqubo ezahlukeneyo, kwaye indlela ye-oxidation eyinxalenye inokusetyenziswa ukuvelisa i-Ammoniian irhasi ye-ammow iRinal igesi. Inkqubo yemveliso ilula kunendlela yendalo yokuguqula igesi, kodwa isixhobo sohlukaniso somoya siyadingeka. Ioksijini eveliswe yiyunithi yokwahlula-hlula isetyenziselwa i-oyile enzima, kwaye i-nitrogen isetyenziswa njengezixhobo ezifudumeleyo ze-Ammonia Synthesis.
I-4. I-Ammonia iMveliso evela kumalahle (i-Coke): Ukuchazwa kwe-haber ye-haber-Bosch ye-Ammonia Synthes, i-Omol kunye neSteam-Steam eqhubekayo, njl. Umzekelo, iqondo lobushushu lokuvelisa igesi ngomyinge we-molar (I-H2) / N2 ye-3.1 ukuya kwi-3.2, ebize igesi yamanzi. Emva kokuba irhasi yamanzi ye-Semi-manzi iyahlanjwa kwaye iqhutywa yibhabheri yegesi, kwaye emva kokuguqulwa yi-carbon diokbon diok broxide kunye ne-carbon diokside. , emva koko wathunyelwa kuAmmonia Synthesis.
