Ammonia gasi inonyungudika sei?

2023-07-28

1. Gasi reammonia rinonyungudutswa sei?

High pressure: kupisa kwakanyanya kweammonia gasiiri 132.4C, kupfuura iyi tembiricha yeammonia gasi haisi nyore kuita liquefy. Asi pasi pekumanikidzwa kwakanyanya, ammonia inogona kunyungudutswa kunyangwe patembiricha iri pasi petembiricha yakaoma. Mumamiriro ezvinhu akajairwa, chero bedzi iyo ammonia pressure iri pamusoro pe5.6MPa, inogona kunyungudutswa mumvura yeammonia.
Tembiricha yakaderera: Kana ichienzaniswa nemamwe magasi, ammonia iri nyore kuita liquefied. Chimwe chezvikonzero chikuru ndechekuti tembiricha yakakosha yeammonia yakaderera. Naizvozvo, ammonia gasi rinonyanya kunyungudutswa pane yakaderera tembiricha. Pakumanikidzwa kwemuchadenga, nzvimbo yekuvira yeammonia inenge 33.34 ° C, uye pakupisa uku, ammonia yatova mumamiriro emvura.
Mumhepo pakupisa kwakanyanya, mamorekuru eammonia anosanganiswa nyore nyore nemamorekuru emvura kuita ammonia mvura, inova mvura yeammonia gasi mhinduro.
Volatility: Iyo molecular chimiro cheammonia gasi iri nyore, simba riri pakati pemamorekuru harina kusimba, uye ammonia gasi rinonyanya kushanduka. Naizvozvo, chero bedzi tembiricha uye kumanikidzwa kwegasi zvakadzikiswa zvakakwana, ammonia gasi rinogona kunyungudutswa nyore.

2. Sei ammonia ichireruka pane mhepo?

Ammonia haina kusimba pane mhepo. Kana huwandu hwemamorekuru hweimwe gasi huchizivikanwa, maererano nehuremu hwayo hwemamorekuru, unogona kuona huwandu hwayo uchienzaniswa nemhepo. Avhareji hama molecular mass of air i 29. calculator its related molecular mass. Kana yakakura kudarika 29, kuwanda kwakakura kudarika mhepo, uye kana iri pasi pemakumi maviri nepfumbamwe, uwandu hudiki pane mhepo.

3. Chii chinoitika kana ammonia yasiiwa mumhepo?

kuputika kunoitika.Ammoniamvura igasi risina ruvara rine kunhuhwirira kwakasimba uye rinonyungudika zviri nyore mumvura. Inogona kuputika kana mhepo ine 20% -25% ammonia. Ammonia mvura ine aqueous solution yeammonia. Chigadzirwa cheindasitiri imvura isina ruvara uye yakajeka ine kunhuhwirira kwakasimba uye kunonhuwirira.

4. Yakawanda sei ammonia ine chepfu mumhepo?

Kana huwandu hweammonia mumhepo huri 67.2mg/m³, nasopharynx inonzwa kutsamwa; apo kusungirirwa kuri 175 ~ 300mg/m³, mhino nemaziso zviri pachena kuti zvinotsamwiswa, uye kufema kwemwoyo kunowedzera kukurumidza; apo kusungwa kunosvika 350 ~ 700mg/m³, vashandi havagoni kushanda; Kana iyo yekusungwa inosvika 1750 ~ 4000mg/m³, inogona kutyisa hupenyu.

5. Ndezvipi zvinoshandiswa neammonia gasi?

1. Kurudzira kukura kwezvirimwa: Ammonia inzvimbo inokosha yenitrogen inodiwa pakukura kwechirimwa, iyo inogona kuvandudza kuorera kwevhu uye kukurudzira kukura nekukura kwemiti.

2. Kugadzirwa kwemafetereza emakemikari: Ammonia chinhu chakakosha pakugadzira fetereza yenitrogen. Mushure mekuita kwemakemikari, inogona kugadzirwa mumvura yeammonia, urea, ammonium nitrate uye mamwe mafetiraiza.

3. Refrigerant: Ammonia ine basa rakanaka refiriji uye inoshandiswa zvakanyanya mukugadzira mafiriji, midziyo yefiriji nemimwe minda.

4. Detergent: Gasi reammonia rinogona kushandiswa kuchenesa girazi, nzvimbo dzesimbi, makicheni, nezvimwewo, uye ine mabasa ekubvisa tsvina, kubvisa kunhuwa, uye kuchenesa.

6. Chigadzirwa chekugadzira ammonia chinoburitsa ammonia sei?

1. Kugadzirwa kweammonia nenzira yeHaber:
N2(g)+3H2(g)⇌2NH3(g) △rHθ=-92.4kJ/mol (maitikiro ezvinhu ari tembiricha yepamusoro, kumanikidzwa kukuru, catalyst)
2. Kugadzirwa kweammonia kubva kugasi rechisikigo: gasi rechisikigo rinobviswa desulfurized kutanga, rozoenda kushandurudzo yechipiri, uyezve rinopinda maitiro akadai sekushandura kabhoni monoxide uye kubviswa kwecarbon dioxide, kuwana musanganiswa wenitrogen-hydrogen, uchiri neinenge 0.1% kusvika 0.3%. yecarbon monoxide uye carbon dioxide (vhoriyamu), mushure mekubviswa nemethanation, gasi rakachena rine hydrogen-to-nitrogen molar ratio ye3 inowanikwa, iyo inomanikidzwa ne compressor uye inopinda muammonia synthesis circuit kuti iwane chigadzirwa ammonia. . Iyo synthetic ammonia yekugadzira maitiro uchishandisa naphtha seyakagadzirwa zvinhu yakafanana neiyi maitiro.
3. Kugadzirwa kweammonia kubva kumafuta anorema: Mafuta anorema anosanganisira mafuta akasara anowanikwa kubva kune akasiyana-siyana maitiro, uye chikamu oxidation nzira inogona kushandiswa kugadzira synthetic ammonia raw material gasi. Maitiro ekugadzira ari nyore kupfuura gasi rechisikigo rekugadzirisa nzira, asi mudziyo wekuparadzanisa mweya unodiwa. Iyo okisijeni inogadzirwa nemhepo yekuparadzanisa unit inoshandiswa kugadzira gasi remafuta anorema, uye iyo nitrogen inoshandiswa seyakagadziriswa ammonia synthesis.
4. Kugadzirwa kweammonia kubva kumarasha (coke): marasha akananga gasification (ona marasha gasification) ane nzira dzakasiyana-siyana dzakadai semhepo yemhepo yakagadzikana yakagadzikana mubhedha intermittent gasification, pressurized oxygen-steam continuous gasification, etc. Somuenzaniso, mukutanga kweHaber-Bosch process ye ammonia synthesis, mhepo uye chiutsi zvakashandiswa segasification agents kuita necoke panguva yakajairika uye tembiricha yakakwira kugadzira gasi ine molar ratio ye (CO+H2)/N2 ye 3.1 kusvika 3.2, inonzi For semi-water gas. Mushure mekunge semi-mvura gasi yagezwa uye yabviswa, inoenda kugasi kabati, uye mushure mekushandurwa nekabhoni monoxide, uye yakamanikidzwa kune imwe kumanikidzwa, inoshambidzwa nemvura yakamanikidzwa kuti ibvise kabhoni dhaokisaidi, uye yozomanikidzwa necompressor. wozogeza ne cuproammonia kubvisa kabhoni monoxide necarbon dioxide. , ndokuzotumirwa kuammonia synthesis.
