Zeolite molecular sieves inoita basa rakakosha muPSA (Pressure Swing Adsorption) hydrogen kugadzira maitiro, uye yavo yakasarudzika adsorption zvimiro ndiyo kiyi yekuwana inonyatso kuchenesa hydrogen. PSA hydrogen kugadzirwa ndeyemuviri adsorption maitiro, inzira yekuparadzanisa gasi iyo inoshandisa akasiyana adsorption masimba emagasi akasiyana pane molecular sieve adsorbent.
Nzira Yekucheneswa KweHydrogen Ndeipi?
Sezvo haidrojeni ichiiswa muzvikamu zvakawanda zvemaindasitiri uye simba, kunyanya mumaseru emafuta uye indasitiri yemagetsi, vane zvinodiwa zvakanyanya, kuchena kwehydrogen chete kunogona kuita izvi zvinodiwa.
Asi iyo haidhirojeni inogadzirwa kubva kune yakabikwa kazhinji ine mhute yemvura uye tsvina yakadai secarbon monoxide, carbon dioxide, methane, nitrogen gasi uye sulfides. Iyi mvura netsvina zvinogona kuchetura ma catalysts, kuderedza kuita basa, corrode midziyo, uye kuisa njodzi yekuchengetedza. Naizvozvo, maitiro ane chekuita nekucheneswa kwehydrogen anonyanya kutarisa pakuomesa uye kubvisa tsvina.
PSA Hydrogen Kugadzirwa uye Kucheneswa
PSA hydrogen kugadzirwa ndeimwe yeanonyanya kushandiswa hydrogen yekuchenesa maitiro muindasitiri. Yakanyatsokodzera kuchenesa hydrogen{{1}iine magasi akasanganiswa akadai secoke oven gasi nemasyngas (natural gas reforming, coal gasification).
PSA hydrogen kucheneswa inoshandisa iyo yakasarudzika yekusarudza adsorption kugona kwema molecular sieves pasi pekumanikidzwa kukuru, kuparadzanisa haidrojeni kubva kune yakasanganiswa gasi. Iwo yunifomu pore saizi yemamorekuru sieves inovatendera kubata mamorekuru ekusachena, uye kuburitsa mamorekuru ehydrogen.
Saizi iyi{{0}nzira yekusabvisa inogonesa kubviswa kwemvura netsvina, ichigadzira yakanyanya-haidhirojeni yakachena yakakodzera kushandiswa kwakakosha. Uye zeolite molecular sieve dzave dombo repakona mukuita uku.
Pasi pekumanikidzwa kwakanyanya, tsvina inoshambadzirwa, nepo hydrogen ichipfuura. Pasi pekumanikidzwa kwakadzika / vacuum, ma molecular sieves desorb (regenerate), achibudisa tsvina. Nenguva nenguva kushandura kudzvanywa, kuchena kwakanyanya kwehydrogen kunogona kuramba kuwanika.
Masife eMamorekuru EHydrogen Kucheneswa
Inlet air pre-treatment: Pamberi pegasi rakasanganiswa (rine hydrogen, mhute yemvura, carbon monoxide, carbon dioxide, methane, nitrogen gas, zvichingodaro) rapinda muPSA system, mhando 3A kana 4A zeolite molecular sieves (kana activated alumina) inodiwa kuti ubvise mvura kutanga.
High pressure adsorption: Kusachena (senge carbon monoxide, carbon dioxide, methane, nitrogen gas, etc.) inogona kushambadzirwa nemhando 5A zeolite molecular sieves, uye dzimwe nguva mhando 13X zeolite molecular sieves inogonawo kushandiswa musanganiswa.
