Nrog rau kev txhim kho ntawm peb lub zej zog, peb tawm tswv yim rau lub zog huv, yog li qhov kev thov rau cov roj av ua lub zog huv kuj nce ntxiv. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntawm kev siv roj av, ntau lub qhov dej roj feem ntau muaj hydrogen sulfide, uas yuav ua rau xeb ntawm cov khoom siv thiab cov kav dej, ua rau ib puag ncig tsis zoo thiab ua rau tib neeg muaj kev noj qab haus huv. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, Kev siv dav dav ntawm cov thev naus laus zis desulfurization roj av tau daws cov teeb meem no, tab sis tib lub sijhawm, tus nqi ntawm kev ntxuav thiab kho cov roj av tau nce ntxiv raws li.
Lub Ntsiab Cai
Molecular sieve desulphurization (tseem hu ua desulfurization) skid, tseem hu ua molecular sieve sweeting skid, yog ib qho khoom siv tseem ceeb hauv kev ua kom huv si lossis cov haujlwm ua kom huv si ntawm cov roj av.
Molecular sieve yog ib hom alkali hlau aluminosilicate siv lead ua los ntawm cov pob txha thiab cov qauv microporous sib xws. Nws yog ib qho adsorbent nrog kev ua tau zoo heev, muaj peev xwm adsorption siab thiab adsorption xaiv. Ua ntej, muaj ntau txoj hauv kev nrog qhov loj me thiab cov qhov zoo nkauj hauv cov qauv molecular sieve, uas tsis tsuas yog muab thaj chaw loj heev, tab sis kuj txwv tsis pub cov molecules loj dua qhov nkag; Qhov thib ob, qhov chaw ntawm molecular sieve muaj polarity siab vim yog cov yam ntxwv ntawm ionic lattice, yog li nws muaj peev xwm adsorption siab rau cov unsaturated molecules, polar molecules thiab polar molecules. Dej thiab hydrogen sulfide yog polar molecules, thiab lub molecular diameter me dua lub pore diameter ntawm molecular sieve. Thaum cov roj nyoos uas muaj cov dej me me hla dhau lub txaj molecular sieve ntawm chav tsev kub, cov dej me me thiab hydrogen sulfide raug nqus, Yog li, cov ntsiab lus ntawm dej thiab hydrogen sulfide hauv cov roj pub raug txo qis, thiab lub hom phiaj ntawm kev qhuav dej thiab desulfurization tau ua tiav. Cov txheej txheem adsorption ntawm molecular sieve suav nrog capillary condensation thiab lub cev adsorption los ntawm van der Waals force. Raws li Kelvin equation, capillary condensation txo qis nrog qhov nce ntawm qhov kub thiab txias, thaum lub cev adsorption yog ib qho txheej txheem exothermic, thiab nws cov adsorption txo qis nrog qhov nce ntawm qhov kub thiab nce nrog qhov nce ntawm qhov siab; Yog li ntawd, cov txheej txheem adsorption ntawm molecular sieve feem ntau yog nqa tawm ntawm qhov kub thiab txias qis thiab siab siab, thaum lub sijhawm analytical regeneration yog nqa tawm ntawm qhov kub thiab txias siab thiab txo qhov siab. Nyob rau hauv qhov kev ua ntawm qhov kub thiab txias siab, huv thiab qis siab regeneration roj, lub molecular sieve adsorbent tso tawm cov adsorbate hauv micropore mus rau hauv cov roj regeneration kom txog thaum tus nqi ntawm adsorbate hauv adsorbent mus txog qib qis heev. Nws kuj muaj peev xwm adsorb dej thiab hydrogen sulfide los ntawm cov roj pub, paub txog kev rov ua dua tshiab thiab rov ua dua tshiab ntawm lub sieve.
