NaOH was added to iron blast furnace slag (BFS)/hydrated lime (HL) slurries to prepare sorbents for semidry and dry flue gas desulfurization (FGD) processes.
It contains water, hydrated lime, a tree protectant and red food color.
However, engineering properties for hydrated lime asphalt mastics at 1.5 dust to binder ratio, couldn't be tested because the specimens were too stiff to mix at this ratio.
"Adding water to lime yields calcium hydroxide (slaked lime, calcium hydrate, hydrated lime, or caustic lime), which is used in mortar, plasters, cements, whitewash, hide dehairing, and water softening and purification and as a source of other calcium salts. "
A differential fixed-bed reactor was employed to study the reaction between iron blast furnace slag (BFS)/hydrated lime (HL) sorbent and SO2 under conditions similar to those in the bag filters of a spray-drying flue gas desulfurization system.
The effect of water on moisture stability of asphalt mixture was studied by simulated test in the laboratory, and the performance of asphalt mixture with hydrated lime additive was analyzed.
HPMC and hydrated lime powder could improve the bleeding, taking into account the fluidity and strength choose the content of hydrated lime is 2%.
The difference of effects of burnt lime and hydrated lime, raw gypsum and burnt gypsum on white cement was studied, and the optimal type of lime and gypsum was determined.
The height of the reactor ensures a suitable particle retention time for the wetting of hydrated lime particles and the chemisorption of SO2/SO3 with the lime.
