Izinzuzo Zomkhiqizo
1.Ukufakwa okulula nokugcinwa sibonga kumklamo we-modular nokwakhiwa.
I-2.Isistimu ezenzakalelayo ngokugcwele yokusebenza okulula nokuthembekile.
3.Ukutholakala okuqinisekisiwe kwamagesi ezimboni ahlanzekile.
4.Kuqinisekiswe ukutholakala komkhiqizo esigabeni esiwuketshezi okufanele ugcinwe ukuze usetshenziswe ngesikhathi sanoma yimiphi imisebenzi yokulungisa.
5.Ukusetshenziswa kwamandla okuphansi.
6.Ukulethwa kwesikhathi esifushane.
Izinkambu Zokusebenza
I-oksijeni, i-nitrogen, i-argon kanye nenye igesi engavamile ekhiqizwa iyunithi yokuhlukanisa umoya isetshenziswa kabanzi ensimbi, kumakhemikhali.
imboni, indawo yokucwenga, ingilazi, irabha, i-electronics, ukunakekelwa kwezempilo, ukudla, izinsimbi, ukukhiqiza ugesi nezinye izimboni.
Ukucaciswa komkhiqizo
- Umgomo wokuklama walesi sitshalo usekelwe endaweni yokubilisa ehlukene yegesi ngayinye esemoyeni. Umoya uyacindezelwa, upholile futhi ukhishwe i-H2O ne-CO2, bese upholiswa kusishintshisi sokushisa esikhulu kuze kube yilapho usuncibilikile. Ngemva kokulungiswa, ukukhiqizwa kwe-oxygen ne-nitrogen kungaqoqwa.
- Lesi sitshalo singowokuhlanza umoya kwe-MS ngenqubo yokukhulisa i-turbine expander. Kuyisitshalo esivamile sokuhlukanisa umoya, esamukela ukugcwaliswa kwezinto eziphelele kanye nokulungiswa kokwenza i-argon.
- Umoya ongahluziwe uya kusihlungi somoya ukuze kukhishwe uthuli nokungcola kwemishini bese ungena kwi-compressor ye-air turbine lapho umoya ucindezelwa khona ube ngu-0.59MPaA. Bese ingena ohlelweni lokupholisa umoya, lapho umoya upholiswa khona ube ngu-17 ℃. Ngemva kwalokho, ageleza ethangini eli-2 le-molecular sieve adsorbing, elisebenza ngokushintshana, ukuze likhishwe i-H2O, CO2 kanye ne-C2H2.

- Ngemva kokuhlanzwa, umoya uhlangana nomoya owandisayo oshiselwe kabusha. Bese icindezelwa yi-pressure compressor ephakathi ukuze ihlukaniswe imifudlana emi-2. Ingxenye eyodwa iya kusishintshisi sokushisa esiyinhloko ukuze ipholiswe ibe ngu-260K, futhi imunce kusukela engxenyeni emaphakathi yesishintshi sokushisa esiyinhloko ukuze ifake i-turbine enwetshiwe. Umoya onwetshiwe ubuyela kusishintshi sokushisa esiyinhloko ukuze ushiselwe kabusha, ngemva kwalokho, ugelezela ku-compressor yokuthuthukisa umoya. Enye ingxenye yomoya ikhuliswa isandisi sokushisa okuphezulu, ngemva kokupholisa, sigelezela kusikhulisi esikhulisa izinga lokushisa eliphansi. Bese iya ebhokisini elibandayo ukuze lipholiswe libe ngu-~170K. Ingxenye yawo isazopholiswa, futhi igeleze iye phansi kwekholomu ephansi ngesishintshi sokushisa. Futhi omunye umoya udonswa esilingweni esincane. i-expander. Ngemuva kokunwetshwa, ihlukaniswe izingxenye ezi-2. Ingxenye eyodwa iya phansi kwekholomu ephansi ukuze ilungiswe, enye ibuyela kusishintshi sokushisa esikhulu, bese igelezela ku-air booster ngemva kokushisisa kabusha.
- Ngemva kokulungiswa okuyisisekelo kukholamu ephansi, umoya owuketshezi kanye ne-nitrogen ewuketshezi emsulwa kungaqoqwa kukholamu engezansi. I-nitrogen ewuketshezi ewuketshezi, umoya owuketshezi kanye ne-nitrogen ewuketshezi ehlanzekile igeleza iye kukholomu ephezulu ngomoya owuketshezi kanye nesipholile se-nitrogen esiwuketshezi. Iphinde ilungiswe kukholomu engenhla, ngemva kwalokho, umoya-mpilo owuketshezi ongu-99.6% ubumsulwa ungaqoqwa ngezansi kwekholomu engenhla, bese ulethwa ngaphandle kwebhokisi elibandayo njengokukhiqizwa.
- Ingxenye yengxenyana ye-argon kukholomu engenhla imuncwa kukholomu ye-argon engahluziwe. Kunezingxenye ezi-2 zekholomu ye-argon engahluziwe. I-reflux yengxenye yesibili ilethwa phezulu kweyokuqala ngepompo eliwuketshezi njenge-reflux. Ilungiswa kukholomu ye-argon engahluziwe ukuze ithole u-98.5% Ar. 2ppm O2 argon ongahluziwe. Bese ilethwa maphakathi nekholomu ye-argon ehlanzekile nge-evaporator. Ngemva kokulungiswa kukholamu ye-argon ehlanzekile, (99.999% Ar) i-argon ye-liquid ingaqoqwa phansi kwekholomu ye-argon ehlanzekile.
- I-nitrogen eyimfucumfucu esuka phezulu kwekholomu engaphezulu igeleza iphuma ebhokisini elibandayo iye kusihlanzi njengomoya ovuselelayo, ukuphumula kuya embhoshongweni wokupholisa.
- I-nitrogen esuka phezulu kwekholomu yomsizi yekholomu engenhla igeleza iphuma ebhokisini elibandayo njengokukhiqizwa nge-cooler kanye nesishintshi sokushisa esiyinhloko. Uma i-nitrogen ingadingeki, ingalethwa embhoshongweni wokupholisa amanzi. Ukuze umthamo obandayo wombhoshongo wokupholisa amanzi unganele, i-chiller idinga ukufakwa.
