Gasi reindasitiri rine huwandu hukuru hwemarara emarara ane akasiyana hydrogen. Kupatsanurwa uye kucheneswa kwehydrogen zvakare imwe yenzvimbo dzekutanga maindasitiri ePSA tekinoroji.
Nheyo yePSA yekuparadzaniswa kwegasi musanganiswa ndeyekuti adsorption kugona kweiyo adsorbent yezvikamu zvakasiyana zvegasi inoshanduka nekuchinja kwekumanikidza. Izvo zvikamu zvehutsvina mugasi rinopinda zvinobviswa ne-high-pressure adsorption, uye izvi zvinosvibisa zvinosvibiswa nekudzikiswa kwekumanikidza uye kukwira kwekushisa. Chinangwa chekubvisa tsvina uye kubvisa zvinhu zvakachena zvinowanikwa kuburikidza nekudzvinyirira uye kuchinja kwekushisa.
PSA hydrogen kugadzira inoshandisa JZ-512H molecular sieve adsorbent kupatsanura hupfumi hwehydrogen kuti ibudise hydrogen, iyo inopedzwa kuburikidza nekumanikidza shanduko yemubhedha weadsorption. Nekuda kwekuti hydrogen inonetsa kushambadza, mamwe magasi (anogona kunzi tsvina) ari nyore kana kuti ari nyore kushambadzwa, saka gasi rehaidhirojeni rakapfuma rinogadzirwa kana rave pedyo nekudzvanywa kwegasi rakagadziriswa. Kusachena kunoburitswa panguva ye desorption (regeneration), uye kudzvanywa kunoderera zvishoma nezvishoma kusvika ku desorption pressure.
Iyo adsorption tower inoshandura maitiro ekushambadzira, kudzvanywa. kuenzana uye desorption kuti uwane inoenderera kugadzirwa kwehydrogen. Hhidrojeni yakapfuma inopinda muhurongwa pasi peimwe dzvinyiriro. Iyo yakapfuma haidrojeni inopfuura nepakati peiyo adsorption tower yakazadzwa neyakakosha adsorbent kubva pasi kuenda kumusoro. Co / CH4 / N2 inochengeterwa pamusoro peiyo adsorbent sechinhu chakasimba chekushambadza chikamu, uye H2 inopinda mumubhedha sechikamu chekushongedza. Chigadzirwa chehydrogen chakaunganidzwa kubva pamusoro peiyo adsorption tower inobuda kunze kwemuganhu. Kana iyo adsorbent mumubhedha yakazadzwa neCO / CH4 / N2, iyo yakapfuma yehydrogen inochinjirwa kune dzimwe adsorption shongwe. Mukuita adsorption desorption, kumwe kudzvanywa kwechigadzirwa hydrogen kuchiri kusara mu adsorbed tower. Ichi chikamu chehaidhirojeni yakachena chinoshandiswa kuenzana uye kupenengura imwe kumanikidza kuenzana shongwe dzakangobviswa. Izvi hazviiti chete kushandisa yasara hydrogen mu adsorption shongwe, asi zvakare inonoke kumhanyisa kusimuka kumhanya mu adsorption tower, inoderedza kuneta dhigirii mu adsorption tower, uye zvinobudirira kuzadzisa chinangwa chekuparadzaniswa kwehydrogen.
JZ-512H molecular sieve inogona kushandiswa kuwana yakakwira kuchena hydrogen.
