1. Kedu ka amonia gas na-esi eme?

Nnukwu nrụgide: okpomọkụ dị egwu nkeamonia gasbụ 132.4C, karịa nke a okpomọkụ amonia gas adịghị mfe liquefy. Ma n'okpuru ọnọdụ nrụgide dị elu, amonia nwere ike ịmịnye ọbụna na okpomọkụ n'okpuru okpomọkụ dị oke egwu. N'okpuru ọnọdụ nkịtị, ọ bụrụhaala na nrụgide amonia dị n'elu 5.6MPa, enwere ike ịgbanye ya n'ime mmiri amonia.
Okpomọkụ dị ala: E jiri ya tụnyere gas ndị ọzọ, amonia na-adị mfe ịgbanye mmiri. Otu n'ime isi ihe kpatara ya bụ na okpomọkụ dị egwu nke amonia dị ntakịrị. Ya mere, gas amonia na-adị mfe karị na obere okpomọkụ. N'ebe nrụgide ikuku ọkọlọtọ, ebe amonia na-esi esi dị ihe dịka 33.34 Celsius C, na okpomọkụ a, amonia abanyelarị na ọnọdụ mmiri mmiri.
N'ikuku na oke okpomọkụ, a na-ejikọta ụmụ irighiri mmiri amonia na mmiri mmiri na-emepụta mmiri amonia, nke bụ mmiri mmiri amonia gas ngwọta.
Volatility: Ọdịdị molekụla nke gas amonia dị mfe, ike dị n'etiti ụmụ irighiri ihe adịghị ike, gas amonia na-agbanwekwa nke ukwuu. Ya mere, ọ bụrụhaala na a na-ebelata okpomọkụ na nrụgide nke gas nke ọma, amonia gas nwere ike ịmịnye ngwa ngwa.

2. Gịnị kpatara amonia ji dị ọkụ karịa ikuku?

Amonia dị obere karịa ikuku. Ọ bụrụ na a maara oke molekụla nke otu gas, dị ka oke molekul ya si dị, ị nwere ike ikpebi njupụta ya ma e jiri ya tụnyere nke ikuku. Nkezi ihe ikwu molekul uka nke ikuku bụ 29. Gbakọọ ya ikwu molekul uka. Ọ bụrụ na ọ karịrị 29, njupụta dị ukwuu karịa ikuku, ma ọ bụrụ na ọ na-erughị 29, njupụta dị ntakịrị karịa ikuku.

3. Kedu ihe na-eme mgbe amonia hapụrụ n'ikuku?

mgbawa na-eme.Amoniammiri bụ gas na-enweghị agba nke nwere isi na-akpasu iwe ma na-agbaze ngwa ngwa na mmiri. Ọ nwere ike ịgbawa mgbe ikuku nwere 20%-25% amonia. Mmiri Amonia bụ ihe ngwọta na-ekpo ọkụ nke amonia. Ngwaahịa mmepụta ihe bụ mmiri mmiri na-enweghị agba na nke na-enweghị isi nke nwere isi ike na-ekpo ọkụ na ose.

4. Kedu ihe amonia na-egbu egbu na ikuku?

Mgbe ntinye nke amonia na ikuku bụ 67.2mg/m³, nasopharynx na-ewe iwe; mgbe itinye uche bụ 175 ~ 300mg / m³, imi na anya na-agbakasị ahụ n'ụzọ doro anya, na ume iku ume obi na-abawanye; mgbe ịta ahụhụ ruru 350 ~ 700mg / m³, ndị ọrụ enweghị ike ịrụ ọrụ; Mgbe ịta ahụhụ ruru 1750 ~ 4000mg / m³, ọ nwere ike na-eyi ndụ egwu.

5. Gịnị bụ ojiji nke amonia gas?

1. Na-akwalite uto osisi: Amonia bụ isi iyi nitrogen dị mkpa maka uto osisi, nke nwere ike imeziwanye ọmụmụ ala ma kwalite uto na mmepe osisi.

2. Imepụta fatịlaịza kemịkalụ: Amonia bụ akụrụngwa dị mkpa maka imepụta fatịlaịza nitrogen. Mgbe mmeghachi omume kemịkalụ gasịrị, enwere ike ịme mmiri amonia, urea, ammonium nitrate na fatịlaịza ndị ọzọ.

3. Refrigerant: Amonia nwere arụmọrụ refrigeration dị mma ma na-ejikarị eme ihe na-emepụta ihe na-eme ka refrigerant, ngwa ngwa na mpaghara ndị ọzọ.

4. Detergent: Enwere ike iji gas Amonia na-ehicha iko, ihe ndị dị n'elu igwe, kichin, wdg, ma nwee ọrụ nke nsị, deodorization, na sterilization.

6. Kedu ka ụlọ ọrụ na-emepụta amonia si emepụta amonia?

1. Mmepụta Amonia site na usoro Haber:
N2(g)+3H2(g)⇌2NH3(g) △rHθ=-92.4kJ/mol (ọnọdụ mmeghachi omume bụ okpomọkụ dị elu, nrụgide dị elu, ihe na-akpali akpali)
2. Amonia na-emepụta site na gas na-emepụta: a na-ebu ụzọ mee ka gas na-emepụta ihe, wee na-eme mgbanwe nke abụọ, ma na-eme usoro dịka ntụgharị carbon monoxide na mwepụ carbon dioxide, iji nweta ngwakọta nitrogen-hydrogen, nke ka nwere ihe dịka 0.1% ruo 0.3% nke carbon monoxide na carbon dioxide (olu), mgbe e wepụsịrị ya site na methanation, a na-enweta gas dị ọcha nke nwere hydrogen-to-nitrogen molar ratio nke 3, nke a na-ejikọta ya na compressor ma banye na sekit synthesis amonia iji nweta ngwaahịa amonia. . Usoro mmepụta amonia sịntetik na-eji naphtha dị ka ihe eji eme ihe yiri usoro a.
3. Mmepụta Amonia sitere na mmanụ dị arọ: mmanụ dị arọ na-agụnye mmanụ fọdụrụnụ nke enwetara site na usoro dị iche iche dị elu, na usoro oxidation akụkụ nwere ike iji mepụta gas amonia sịntetik. Usoro mmepụta dị mfe karịa usoro mgbanwe ikuku ikuku gas, mana achọrọ ngwaọrụ nkewa ikuku. A na-eji ikuku oxygen na-emepụta site na ngalaba nkewa ikuku maka gasification nke mmanụ dị arọ, a na-ejikwa nitrogen dị ka ihe eji eme ihe maka njikọ amonia.
4. Amonia mmepụta si coal (coke): coal kpọmkwem gasification (lee coal gasification) nwere ụzọ dị iche iche dị ka ikuku mgbali ofu bed intermittent gasification, pressurized oxygen-steam na-aga n'ihu gasification, wdg Ka ihe atụ, na mmalite Haber-Bosch usoro maka A na-eji amonia synthesis, ikuku na uzuoku mee ihe dị ka ndị na-emepụta gasification na-emeghachi omume na coke na nrụgide nkịtị na okpomọkụ dị elu iji mepụta gas na molar ratio nke (CO + H2) / N2 nke 3.1 ruo 3.2, nke a na-akpọ Maka ọkara mmiri gas. Mgbe a na-asachapụ gas nke ọkara mmiri ma wepụ ya, ọ na-aga na kabinet gas, ma mgbe carbon monoxide gbanwee ya, ma tinye ya na nrụgide ụfọdụ, a na-asa ya na mmiri nrụgide iji wepụ carbon dioxide, wee kpoo ya na compressor. wee saa ya na cuproamonia iji wepụ obere carbon monoxide na carbon dioxide. , wee ziga ya na njikọ amonia.
