Ib qho tseem ceeb uas yuav tsum tau ua ua ntej rau kev siv cov tshuaj tsuag qhuav gum sulfur dav dav yog seb nws puas daws tau qhov teeb meem ntawm kev txhim kho thiab kev siv ntau ntawm cov hmoov sulfate tom qab ziab. Nws tuaj yeem rov ua dua tshiab ua cov khoom nqus dej, ib feem ntawm cov khoom qhuav tuaj yeem rov ua dua tshiab, raws li cov av ntxiv, tig mus ua cov khoom siv nplaum siv rau cov cement retarder, ua los ntawm cov xuab zeb dag granular ...

Raws li lub ntiaj teb kev siv hluav taws xob nce ntxiv txhua xyoo, kev hlawv thiab siv cov thee ua lub hauv paus tseem ceeb ntawm lub zog, tso tawm ntau cov sulfur dioxide nrog rau kev tsim cov kua qaub hauv cheeb tsam, tau ua rau muaj kuab paug rau ib puag ncig, uas cuam tshuam rau qhov sib npaug ntawm ecological, ua rau muaj kev puas tsuaj loj ntawm cov hav zoov, acidification ntawm cov av thiab pas dej, thiab xeb ntawm cov tsev.

Yog li ntawd, kev tswj thiab txo cov pa roj sulfur dioxide yog ib txoj haujlwm tseem ceeb. Ntawm ntau cov thev naus laus zis desulfurization, kev siv txoj kev tsuag kom qhuav kom tshem tawm sulfur dioxide ntawm cov pa roj flue yog ib txoj kev siv tshuab uas tau txais kev saib xyuas ntau dua. Cov thev naus laus zis no tau kawm thawj zaug hauv xyoo 1970 thiab tau muab tso rau hauv kev lag luam thaum xyoo 1970. Nws muaj kev nqis peev tsawg dua, kev ua haujlwm yooj yim, kev tshem tawm sulfur siab, tsis muaj kuab paug thib ob, thiab piv rau txoj kev ntub dej siv ntau hauv cov roj flue desulfurization, cov khoom hmoov tsim los ntawm txoj kev tsuag kom qhuav ntawm desulfurization muaj kev xaiv ntau dua thiab tus nqi txhim kho.

Cov txheej txheem gel sulfur uas siv tau rau kev ziab tuaj yeem siv tau dav, ib qho tseem ceeb uas yuav tsum tau ua yog seb nws puas daws tau qhov teeb meem ntawm kev tsim thiab siv ntau cov hmoov sulfate tom qab ziab. Nws tuaj yeem rov ua dua tshiab ua cov khoom nqus dej, ib feem ntawm cov khoom qhuav tuaj yeem rov ua dua tshiab, ua cov khoom ntxiv rau hauv av, hloov mus ua cov khoom siv nplaum rau cov cement retardant, ua los ntawm cov xuab zeb thiab pob zeb dag, ua cov khoom sau rau cov ntaub ntawv tsim kho es tsis txhob siv cov pob zeb thiab asphalt thiab lwm yam.
