Txoj Cai

Molecular sieve desulphurization (desulfurization) skid, tseem hu ua molecular sieve sweeting skid, yog ib qho khoom siv tseem ceeb hauv cov roj purifying lossis natural gas conditioning. Molecular sieve yog alkali hlau aluminosilicate siv lead ua nrog cov qauv tsim thiab cov qauv microporous zoo ib yam. Thaum cov pa roj uas muaj cov kab dej nkag mus los ntawm lub txaj molecular sieve ntawm chav tsev kub, cov kab dej thiab mercaptan tau nqus, yog li txo cov dej thiab mercaptan cov ntsiab lus hauv cov roj pub, paub txog lub hom phiaj ntawm lub cev qhuav dej thiab desulfurization. Cov txheej txheem adsorption ntawm molecular sieve suav nrog capillary condensation thiab lub cev adsorption tshwm sim los ntawm van der Waals quab yuam. Los ntawm kev sib npaug ntawm Kelvin, nws tuaj yeem pom tias capillary condensation tsis muaj zog nrog qhov nce ntawm qhov kub thiab txias, thaum lub cev adsorption yog txheej txheem exothermic, thiab nws cov adsorption tsis muaj zog nrog qhov kub thiab txias thiab nce nrog kev nce siab; Yog li ntawd, cov txheej txheem adsorption ntawm molecular sieve feem ntau yog nqa tawm ntawm qhov kub thiab txias, thaum lub desorption regeneration yog nqa tawm ntawm qhov kub thiab txias. Nyob rau hauv qhov kev txiav txim ntawm qhov kub thiab txias, huv si thiab tsis tshua muaj siab regeneration gas, molecular sieve adsorbent tso tawm adsorbate nyob rau hauv lub micropore mus rau regeneration gas ntws mus txog rau thaum tus nqi ntawm adsorbate nyob rau hauv lub adsorbent mus txog ib tug tsawg kawg nkaus theem, thiab muaj peev xwm nqus dej thiab mercaptan los ntawm cov pub roj, realizing lub regeneration thiab recycling txheej txheem ntawm molecular sieve.

Cov txheej txheem thev naus laus zis

Cov txheej txheem ntws ntawm cov roj molecular sieve desulphurization (desulfurization) skid yog qhia hauv daim duab. Lub tsev siv peb txoj kev ntauwd, ib tus pej thuam adsorption, ib tug pej thuam regeneration thiab ib tug pej thuam txias. Tom qab tshem tawm cov entrained hydrocarbon kua los ntawm pub roj lim cais, cov roj pub nkag mus rau hauv molecular sieve desulfurization ntauwd. Cov dej thiab mercaptan hauv cov pa roj yog adsorbed los ntawm molecular sieve kom paub txog lub cev qhuav dej thiab mercaptan adsorption txheej txheem. Cov roj purified los ntawm lub cev qhuav dej thiab kev tshem tawm mercaptan nkag mus rau hauv cov khoom siv roj av lim kom tshem tawm cov hmoov av molecular sieve, thiab tom qab ntawd nws raug xa tawm raws li cov khoom siv roj.

Molecular sieves yuav tsum tau regenerated tom qab adsorbing ib tug npaum li cas ntawm cov dej thiab mercaptan. Tom qab lim cov khoom siv roj av, ib feem ntawm cov khoom siv roj yog muab rho tawm los ua cov roj regeneration. Tom qab cov roj tau rhuab mus rau 300 ℃ los ntawm cov cua kub cua sov, tus pej thuam maj mam rhuab mus rau 272 ℃ los ntawm molecular sieve desulfurization ntauwd uas tau ua tiav cov txheej txheem adsorption los ntawm hauv qab mus rau sab saum toj, kom cov dej thiab mercaptan adsorbed ntawm molecular sieve yuav raug muab cais tawm thiab ua cov nplua nuj regeneration txheej txheem.
