Okukola oxygen mu makolero n’obujjanjabi, kye kimu ku bikulu ebikozesebwa mu zeolite molecular sieves. Kisunsula molekyo za nayitrojeni nga kiyita mu nsengekera y’obutuli entuufu, bwe kityo ne kyawula bulungi okisigyeni ow’obulongoofu obw’amaanyi okusobola okutuukiriza ebyetaago by’obujjanjabi, eby’amakolero n’eby’awaka.
Enkola ya Molecular Sieve Enkola y’okukola oxygen
Pressure swing adsorption (PSA): Empewo enyigirizibwa eyita mu kitanda kya molekyu ekisengejja. Mu kiseera ky’okunyigiriza, ekisengejja kya molekyu kinyiga nayitrojeni, ne kigaggawaza okisigyeni okusobola okufulumya. Mu kiseera ky’okukendeeza puleesa, nayitrojeni afuluma, n’azzaawo ekisengejja kya molekyu.
Vacuum pressure swing adsorption (VPSA): Wansi w’okunyigirizibwa, empewo eyingira mu munaala gw’okusikiriza, nga eno ssefuliya ya molekyu esengejja nayitrojeni mu ngeri elondamu, n’egaggawaza okisigyeni okusobola okufulumya. Oluvannyuma kyusa ku vacuum, okuggya nayitrojeni n’okuddamu okukola molekyu sieve.
Vacuum swing adsorption (VSA): Ku puleesa eya bulijjo oba puleesa entono, empewo eyingira mu munaala gw’okusikiriza, nayitrojeni asinga kukwatibwa molekyu ssefuliya, era okisigyeni n’akulukuta n’afuluma. Wansi w’obuziba, nayitrojeni anywezeddwa afulumizibwa era ekisengejja kya molekyu ne kiddamu okutondebwa.
Okwawula empewo mu ngeri ya cryogenic: Nyigiriza empewo okutuuka mu mbeera y’amazzi era oyawule okuyita mu nkola ya distillation. Nayitrojeni asooka kufuumuuka olw’obuziba bwayo obutono, ate okisigyeni akuŋŋaanyizibwa mu mbeera y’amazzi okusobola okufulumya. Ebisengejja molekyu bikozesebwa okusooka okulongoosa empewo okuggyawo obunnyogovu ne kaboni dayokisayidi.
Enkozesa Y'Enkola Ya Oxygen Enjawulo
PSA esaanira okufulumya oxygen etambuzibwa oba ey'obujjanjabi, n'okufulumya oxygen mu makolero entono oba eya wakati, obulongoofu bwa oxygen buli 90% ~ 95%.
VPSA esaanira okukola oxygen mu makolero amanene, nga ekuuma oxygen nga tekyukakyuka waggulu wa 93%.
VSA esaanira okufulumya oxygen obutasalako ku mutendera ogwa wakati (eddwaliro eddene, obulunzi bw’omu mazzi, bboyiyira z’amakolero n’ebirala), oxygen concentration is 90%~95%.
Cryo-okwawula kuwa obusobozi obw’enjawulo obw’okufulumya ku mutendera omunene era kufulumya obulongoofu bwa okisigyeni obusinga obunene (mu ngeri entuufu okusinga 99.6%), okutuukiriza ebyetaago eby’omulembe-ebya semikondokita, eby’omu bwengula. Kikozesebwa nnyo mu byuma, eddagala, ebyuma, n’ebyuma.
Zeolite Molecular Sieves Okukola Oxygen
Ekika kya 5A zeolite molecular sieve: Ekwata molekyu entonotono nga nayitrojeni ne kaboni dayokisayidi, naye erina obusobozi obutono obw’okusikiriza okisigyeni. Ekika kino eky’okusengejja molekyu kyakozesebwa nnyo mu nkola za PSA ezasooka ez’okukola oxygen.
Ekika kya 13X zeolite molecular sieve: Kisinga kukozesebwa mu kulongoosa empewo nga tennabaawo mu kukola okisigyeni, okusinga butereevu mu nkola y’okusikiriza omusingi (core adsorption process) okwawula okisigyeni ne nayitrojeni. Kirina obusobozi bungi obw’okusikiriza naddala ku bunnyogovu, kaboni dayokisayidi, ne salufayidi.
Ekika kya LiX zeolite molecular sieve: Enkyusa ekyusiddwa eya X-type molecular sieve (enkyukakyuka ya 13X), nga erina okulonda kwa nayitrojeni okusingako n’emiwendo gy’okusikiriza n’okuggyamu amangu, mu kiseera kino ye molekyu esinga okukola obulungi-okukola okisigyeni.
