I-ammonia igesi i-amomonia isebenza kanjani?
1. I-ammonia igesi isebenza kanjani?
Ingcindezi ephezulu: izinga lokushisa elibucayi le igesi ye-ammonia ngu-132.4C, ngaphezu kwalolu gesi lokushisa i-ammonia akulula ukuluhlaza. Kepha ngaphansi kwezimo eziphakeme zokucindezela, i-ammonia ingahle ifakwe emazingeni okushisa ngaphansi kwezinga lokushisa elibucayi. Ngaphansi kwezimo ezijwayelekile, inqobo nje uma ingcindezi ye-ammonia ingaphezulu kwe-5.6MPA, ingafakwa emanzini akwa-ammonia.
Ukushisa okuphansi: Uma kuqhathaniswa namanye amagesi, i-ammonia kulula ukuba i-liquefied. Enye yezizathu eziphambili ukuthi izinga lokushisa elibucayi le-ammonia liphansi. Ngakho-ke, i-ammonia igesi isebenza kalula ngamazinga okushisa aphansi. Ekucindezelweni okujwayelekile komkhathi, iphuzu elibilayo lase-ammonia licishe libe ngu-33.34 ° C, nakuleli lokushisa, i-ammonia selivele lisesimweni se-liquid.
Emoyeni ekushiseni okuphezulu, amamolekyuli e-ammonia ahlanganiswa kalula ngama-molecule amanzi ukuze akhe amanzi e-ammonia, okuyikhambi legesi ka-ammonia.
Ukuqina: Ukwakheka kwamangqamuzana kwegesi ye-ammonia kulula, amandla phakathi kwama-molecule abuthakathaka, futhi igesi ye-ammonia iguquguquka kakhulu. Ngakho-ke, inqobo nje uma izinga lokushisa nengcindezi yegesi yehliswe ngokwanele, i-ammonia igesi ingalingisa kalula.
2. Kungani i-ammonia ilula kunomoya?
I-ammonia inkathi emnyama emnyama kunomoya. Uma ubukhulu be-molecular molecular yegesi ethile yaziwa, ngokuya ngesisindo sayo se-molecular, ungahlulela ukuqina kwaso uma kuqhathaniswa nomoya. Isilinganiso se-molecular molecular molecular somoya singu-29. Bala isisindo saso samangqamuzana. Uma kukhulu kune-29, ukuqina kukhulu kunomoya, futhi uma kungaphansi kwama-29, ubuningi buncane kunomoya.
3. Kwenzekani lapho i-ammonia ishiywe emoyeni?
ukuqhuma kwenzeka. Amoniya Amanzi igesi engenamibala enephunga elinamandla elicasulayo futhi lincibilika kalula emanzini. Kungaqhuma lapho umoya uqukethe ama-20% -25% ammonia. Amanzi e-ammonia yisisombululo esinamanzi se-ammonia. Umkhiqizo wezimboni uwuketshezi olungenamibala futhi olusobala olunephunga elinamandla futhi elinamapuleti.
4. Malini i-ammonia enobuthi emoyeni?
Lapho ukugcwala kwe-ammonia emoyeni kungu-67.2mg / m³, i-nasopharynx izizwa icasukile; Lapho okuhlushwa kungu-175 ~ 300mg / m³, ikhala namehlo acasulwa, futhi izinga lokuphefumula liyashesha; Lapho ukugcwala kufinyelela ku-350 ~ 700mg / m³, abasebenzi abakwazi ukusebenza; Lapho okuhlushwa kufinyelela ku-1750 ~ 4000mg / m³, kungasongela impilo.
5. Yini ukusetshenziswa kwegesi kaMmonia?
1. Khuthaza ukukhula kwezitshalo: I-Amoniya ngumthombo obalulekile we-nitrogen odingekayo ekukhuleni kwezitshalo, okungathuthukisa ukuzala kwenhlabathi futhi akhuthaze ukukhula kwezitshalo nentuthuko.
2 Ngemuva kokusabela kwamakhemikhali, kungenziwa ngamanzi e-ammonia, urea, i-ammonium nitrate nomunye umanyolo.
I-3. Isiqandisi: I-ammonia inokusebenza kahle kwesiqandisi futhi isetshenziswa kabanzi ekwakheni iziqandisini, imishini yokuqandisa kanye nezinye izinkambu.
I-4. Ukuhlanza: Igesi ye-ammonia ingasetshenziswa ukuhlanza ingilazi, indawo yensimbi, amakhishi, njll.
6. Isitshalo se-ammonia se-ammonia sikhiqiza kanjani i-ammonia?
1. Ukukhiqizwa kwe-ammonia ngendlela ye-haber:
I-N2 (g) + 3h2 (g) ⇌2NHH3 (g) △2nh3 (g) △ i-rθ = -92.4kj / mol (izimo zokuphendula zishisa kakhulu, ingcindezi ephezulu, i-catalyst)
2. Ukukhiqizwa kwe-ammonia kusuka kugesi yemvelo: Igesi yemvelo ihlelekile kuqala, bese ithola izinqubo ezinjengokuthi i-Carbon Dioxide ukuguqulwa, ukuthola i-0.1% ye-Carrogen, i-Carrogen Dioxide (ivolumu), ngemuva kokususwa yi-methanation, igesi emsulwa ene-a I-Hydrogen-to-nitrogen molar ratio of 3 iyatholakala, ecindezelwe yi-compressor futhi ingena kwi-ammonia syntout circuit ukuthola umkhiqizo i-ammonia. Inqubo yokwenza ukukhiqiza ye-anmonia isebenzisa uNaphtha njengoba impahla eluhlaza iyafana nale nqubo.
I-3. Ukukhiqizwa kwe-ammonia kusuka kumafutha asindayo: Amafutha anesisindo afaka uwoyela osele atholakele ezinqubweni ezahlukahlukene ezithuthukile, futhi indlela eyingxenye ye-oxidation ingasetshenziswa ukukhiqiza igesi yokwenziwa i-ammonia eluhlaza. Inqubo yokukhiqiza ilula kunendlela yemvelo ye-Steam Steam Remorvering, kepha idivaysi yokwehlukanisa komoya iyadingeka. I-oksijini ekhiqizwa yiyunithi yomoya yokwehlukaniswa komoya isetshenziselwa ukuhlukaniswa kwamafutha asindayo, futhi i-nitrogen isetshenziswa njengento eluhlaza ye-ammonia synthesis.
4. Ukukhiqizwa kwe-ammonia kusuka kumalahle (coke): I-Coal Direct Gasezation (bheka i-Coal Photization) inezindlela ezahlukahlukene ezifana ne-armor-bosch yenqubo yokuthola i-ammonia, i-oxygen-steam complious, i-oxygen-steam complication for anthents yokuhlelwa kwe-ammonia, i-oxygen-steam complious, i-ancygen-steam complication for anthents ukusabela nge-cocket evamile nokushisa okuphezulu ukukhiqiza igesi ngesilinganiso se-molar of (CO + H2) / N2 ka-3.1 kuye ku-3.2, ibizwa ngegesi yamanzi. Ngemuva kokuthi igesi yamanzi ami-amanzi iyagezwa futhi inikezelwe, iya kwikhabethe legesi, futhi ngemuva kokuguqulwa ngengcindezi ethile, igezwe ngama-comprononia ukuze ikhiphe i-compron dioxide kanye ne-carbon dioxide encane. , wabe esethumela ku-ammonia synthesis.
