LPG Desulfurization Catalyst

Khoom Description

Petroleum refining txheej txheem, coking, atmospheric, siab, catalytic cracking sharks tsim liquefied petroleum gas muaj ib tug ntau ntawm sulfide, sulfide yuav ua rau cov txheej txheem tom ntej catalyst lom thiab inactivation, ob lub ntsiab ntawm sulfur thiab hydrogen sulfide corrosion ntawm pipeline thiab cia ntim, raws li ib tug pej xeem. roj, yuav tsim SOX cov pa phem ib puag ncig, tsim cov kua qaub los nag, thiab lwm yam. Tam sim no, tag nrho cov ntsiab lus sulfur ntawm LPG yuav tsum tau ua roj hauv tsev thiab txawv teb chaws. Yog tias nws siv los ua cov khoom siv tshuaj lom neeg, nws tseem nruj dua. Tuam Tshoj tus qauv roj liquefied (GB1174.1997) qhia tias tag nrho cov sulfur pawg feem hauv LPG tsawg dua 343mg / m3, Yog li kev tshem tawm tob ntawm sulfide hauv LPG muaj qhov tseem ceeb ntawm kev lag luam thiab ib puag ncig qhov tseem ceeb.

Tam sim no, kev lag luam hauv tsev thiab txawv teb chaws desulfurization feem ntau yog muab faib ua desulfurization qhuav, ntub stripping thiab molecular sieve desulfurization yog ib txwm muaj, thiab cov txheej txheem kuj mature. Txawm li cas los xij, tus nqi ntub dej desulfurization catalyst yog siab heev, thiab cov khoom tsim tau cuam tshuam rau qee yam. Nyob rau hauv cov txheej txheem ntau lawm, nws yog ib qho yooj yim uas yuav ua rau muaj kev huam yuaj ntawm khiav poob ntawm liquefied roj, uas ua rau insecurity ntawm ntau lawm. Vim yog siv cov kua caralkali ua rau ib puag ncig siab.

Molecular sieve adsorption desulfurization muaj qhov zoo ntawm tsis muaj alkali ntxuav, tsis muaj kuab paug, thiab adsorption nyob rau hauv chav tsev kub, tab sis nws yuav tsum tau regenerated ntawm txog 300 degree qhov kub thiab txias, yog li nce tus nqi khiav hauj lwm, thiab lub peev peev yog loj. Yog li ntawd, lub desulfurization ntawm txhiab LPG rau molecular sieve yog txwv.
