Lub twj tso kua mis desulfurization slurry ua lub luag haujlwm tseem ceeb hauv cov roj ntub dej desulfurization (FGD) qhov system, feem ntau yog lub luag haujlwm rau kev nyab xeeb thiab ua haujlwm zoo thauj khoom hnyav, siab -khoom-cov ntsiab lus (20%-40%) gypsum slurry (cov khoom tseem ceeb yog ₃ / CaSO ₃). Tshwj xeeb, nws ua cov haujlwm hauv qab no:
Thauj cov slurry generated nyob rau hauv lub absorption ntauwd rau dewatering khoom (xws li lub tshuab nqus tsev lim), kom ntseeg tau lub continuation ntawm cov tshuaj tiv thaiv desulfurization;
Txuas cov concentration thiab dewatering theem los ntawm kev kaw- lub voj voog ncig, tswj kev ruaj ntseg ntawm cov txheej txheem desulfurization. Cov khoom siv no, nrog nws cov corrosion-cov ntaub ntawv tiv taus thiab cov qauv tsim tshwj xeeb, tuaj yeem ua haujlwm hnyav nrog cov ntsiab lus ntawm txog 40%, cuam tshuam ncaj qha rau qhov kev ua haujlwm desulfurization efficiency (txog 95% lossis ntau dua) thiab cov teebmeem txo qis.
