Zeolite molecular sieves akakosha mukutanga{{0}kucheneswa kweindasitiri yekuparadzanisa mweya ye cryogenic. Rukova rwemhepo runofanira kupfuura nemubhedha rema molecular sieve isati yapinda muchikamu chikuru chekuparadzanisa mhepo, kubvisa tsvina inogona kukanganisa maitiro e cryogenic kana kukanganisa kunaka kwechigadzirwa.
Chii chinonzi Cryogenic Air Separation Technology?
Cryogenic air separation tekinoroji yakavakirwa pamisiyano yekubikira mapoinzi emagasi anokonzeresa, kutanga kutonhora mhepo kusvika kune yakanyanya kuderera tembiricha (yakaderera pane iyo yekubikira yegasi chikamu chegasi), kazhinji pazasi -180 dhigirii, uyezve inoshandisa iyo yekubikira mutsauko kudhiza nekuparadzanisa magasi.
Cryogenic air separation tekinoroji inoshandiswa zvakanyanya musimbi, makemikari, zvemagetsi, zvekurapa, zvemuchadenga nemamwe minda. Ndiyo nzira yepakati yekuparadzanisa gasi remaindasitiri, uye parizvino ndiyo nzira yakanyanya kukura uye inoshanda yekugadzira maindasitiri okisijeni, nitrogen, argon uye magasi asingawanzo.
Maitiro Ekupatsanura Mhepo neCryogenic Distillation
Cryogenic distillation air separation process inowanzobatanidza matanho matanhatu anotevera:
Kutsikirira kwemhepo: Dzvinyirira mhepo nematanho akawanda emacompressor, kupa kudzvanywa kunodiwa kwekutonhodza kwemhepo uye kuparadzaniswa kunotevera. The pressure range inogona kuva 0.5Mpa ~ 0.8Mpa (normal pressure device), kana 3Mpa ~ 6Mpa (high pressure device).
Pre-kutonhodza: Dzikisa tembiricha yemhepo kusvika panonyungudutswa neinotonhorera (kazhinji mvura inotonhodza kana mufiriji), ingangoita madhigirii mashanu kusvika pagumi, zvichideredza simba rinodiwa pakupatsanurwa kwemhepo kunotevera.
Pre-kucheneswa: Shandisa adsorption towers (yakaiswa mamolecular sieves, activated alumina nemamwe adsorbents) kubvisa tsvina yakaita semwando, carbon dioxide nemahydrocarbons, kudzivirira kudzikira{1}}tembiricha yekutonhora nekuvharika kwemidziyo, kuve nechokwadi chekuchengetedzwa kwe cryogenic process.
Kutonhora kwakadzika: Mhepo yakanatswa inotsinhanisa kupisa nemhepo inotonhora inoyerera, zvishoma nezvishoma ichitonhora ichidzika kusvika kune liquefaction tembiricha, ingangoita -170 dhigirii kusvika -180 dhigirii, uye imwe gasi mumhepo inonyungudika.
Distillation separation: The high pressure column inopatsanura kunze kweokisijeni{{0}yakapfuma mvura uye nitrogen-yakapfuma mvura. Yakakwira-yakachena okisijeni nenitrogen zvinowanwa kubva mukoramu yakaderera mushure mekuwedzera distillation. Uye iyo argon gasi inotungamirwa kubva pakati peiyo yakaderera yekumanikidza column.
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%) iripo pakukumbira.
Masefa eMolecular For Cryogenic Air Separation
13X-APG Zeolite Molecular Sieve: Yakagadzirwa zvakanyanya kuitira air cryogenic air separation industry, inoshanda kune chero saizi ye air cryo-separation devices. 13X-APG ine yakasimba selective adsorption capacity yemvura necarbon dioxide.
13X-HP Zeolite Molecular Sieve: Ine yakakwira okisijeni nenitrogen kupatsanurwa uye mwero wakakwana wekugadzirwa kweokisijeni, iyo inonyanya kushandiswa kugadzira mayuniti okisijeni kuisa kupatsanurwa kweokisijeni nenitrogen, zvichiita kuti muindasitiri neokisijeni iwedzere.
13X-APG-III Zeolite Molecular Sieve: Imhando yepamusoro ye13X-APG. Iko adsorption performance yezeolite 13X-APG-III ndeye 60%~70% yepamusoro pane iya ye13X-APG. Kunyangwe pakaderera carbon dioxide mamiriro, adsorption capacity ye13X-APG-III ichiri kushanda zvakanaka.
13X-APG-V Zeolite Molecular Sieve: The adsorption performance ye13X-APG-V inopeta kaviri pane 13X-APG, uye inodarika ka1.4 iya ye 13X-APG-III. 13X-APG-V molecular sieve chinhu chinotungamira muindasitiri yekuparadzanisa mweya ye cryogenic, uye zviratidzo zvayo zvekushanda zvakakura kudarika zvakaitangira.
