Zeolite molecular sieves kikulu nnyo mu nkola ya pre-okulongoosa mu makolero g’okwawula empewo mu cryogenic. Omugga gw’empewo gulina okuyita mu kitanda kya molekyu ezisengejja nga tegunnayingira mu kitundu ekikulu eky’okwawula empewo, okuggyawo obucaafu obuyinza okutaataaganya enkola ya cryogenic oba okukosa omutindo gw’ebintu.
Tekinologiya w’okwawula empewo mu ngeri ya Cryogenic kye ki?
Tekinologiya w’okwawula empewo mu ngeri ya cryogenic yeesigamiziddwa ku njawulo mu bifo ebifumbirwamu ggaasi ezikola, asooka kunyogoza empewo okutuuka ku bbugumu eri wansi ennyo (wansi okusinga ekifo ky’okufumba kwa buli kitundu kya ggaasi), ebiseera ebisinga wansi wa -180℃, n’oluvannyuma n’akozesa enjawulo y’okufumba okufuumuula n’okwawula ggaasi.
Tekinologiya w’okwawula empewo mu ngeri ya cryogenic akozesebwa nnyo mu byuma, eddagala, ebyuma, eby’obujjanjabi, eby’omu bwengula n’ebirala. Ye nkola enkulu ey’okwawula ggaasi z’amakolero, era mu kiseera kino y’enkola esinga okukula era ekola obulungi mu kukola mu makolero okisigyeni, nayitrojeni, argon ne ggaasi ezitatera kulabika.
Enkola y’okwawula empewo mu Cryogenic Distillation
Enkola y’okwawula empewo mu cryogenic distillation etera okubeeramu emitendera omukaaga gino wammanga:
Okunyigiriza empewo: Puleesa empewo n’emitendera mingi egy’okunyigiriza, okusobola okuwa puleesa eyeetaagisa okunyogoza empewo n’okwawukana okuddirira. Puleesa eyinza okuba 0.5Mpa ~ 0.8Mpa (ekyuma kya puleesa ekya bulijjo), oba 3Mpa ~ 6Mpa (ekyuma kya puleesa eya waggulu).
Pre-cooling: Wansi ebbugumu ly’empewo okutuuka ku kifo ky’okufuuka amazzi n’ekinyogoza (ebiseera ebisinga amazzi aganyogoza oba firiigi), nga diguli 5 okutuuka ku diguli 10 , ekikendeeza ku maanyi ageetaagisa mu kwawula kw’empewo okw’ekika kya cryogenic okuddirira.
Okulongoosa nga tonna-: Kozesa eminaala egy’okusikiriza (egitikkiddwamu ebisengejja molekyu, alumina ekola n’ebisikiriza ebirala) okuggya obucaafu nga obunnyogovu, kaboni dayokisayidi ne haidrokaboni, okuziyiza okutonnya n’okuzibikira ebyuma mu bbugumu eri wansi, okukakasa obukuumi bw’enkola ya cryogenic.
Okunyogoza okw’amaanyi: Empewo erongooseddwa ewanyisiganya ebbugumu n’okutambula kw’empewo ennyogovu, mpolampola n’etonnya okutuuka ku bbugumu ly’okufuuka amazzi, nga diguli -170 okutuuka ku diguli -180 , era ezimu ku ggaasi mu mpewo zifuuka amazzi.
Okwawula mu kusengejja: Empagi ya puleesa eya waggulu eyawula amazzi agalimu okisigyeni-n’amazzi agalimu nayitrojeni-. Okisigyeni ne nayitrojeni eby’obulongoofu obw’amaanyi-bifunibwa okuva mu mpagi ya puleesa entono oluvannyuma lw’okwongera okufuumuula. Era omukka gwa argon gukulemberwa okuva wakati mu mpagi ya puleesa entono.
Gas extraction and storage: Oxygen, nitrogen and argon are reheated to gas and and then output. Some are liquefied for storage, such as liquid oxygen and liquid nitrogen. However, high purity oxygen (>99.5%), nitrogen (>99.9%), and argon (>99.9%) zifunibwa nga zisabiddwa.
Molecular Sieves Okusobola Okwawula Empewo Ya Cryogenic
13X-APG Zeolite Molecular Sieve: Ekoleddwa mu ngeri ey’enjawulo ku makolero g’okwawula empewo mu cryogenic empewo, ekozesebwa ku sayizi yonna ey’ebyuma ebyawula empewo cryo-{3}}X-APG erina obusobozi obw’amaanyi obw’okulonda okusikiriza amazzi ne kaboni dayokisayidi.
13X-HP Zeolite Molecular Sieve: Eriko omulimu gwa waggulu ogw’okwawula okisigyeni ne nayitrojeni n’omutindo gw’okufulumya okisigyeni ogumala, ogusinga okukozesebwa mu yuniti ezikola okisigyeni okussa mu nkola okwawula okisigyeni ne nayitrojeni, ekifuula okugaggawaza okisigyeni mu makolero n’eby’obujjanjabi.
13X-APG-III Zeolite Molecular Sieve: Kika kya 13X-APG eky’omulembe. Omulimu gw’okusikiriza ogwa zeolite 13X-APG-III guli waggulu ebitundu 60%~70% okusinga ogwa 13X-APG. Ne mu mbeera za kaboni dayokisayidi entono, obusobozi bw’okusikiriza bwa 13X-APG-III bukyakola bulungi.
13X-APG-V Zeolite Molecular Sieve: Omulimu gw’okusikiriza ogwa 13X-APG-V gusukka emirundi ebiri egya 13X-APG, ate emirundi egisukka mu 1.4 egya 13X-APG-III. 13X-APG-V molekyu sieve kintu kikulembedde mu makolero g’okwawula empewo mu cryogenic, era ebiraga omulimu gwayo bisukkulumye nnyo ku byasooka.
