Efficient production of hydrated lime generation

Lime application for the efficient production of ...

Because NaOH is expensive, we sought to minimize the cost of our process by substituting hydrated lime and saccharate of lime (lime sucrate) in its place. The yield of glucooligosaccharides using either 5 % lime (41.4 ± 0.5 g/100 g) or 5 % lime sucrate (40.0 ± 1.4 g/100 g) were both similar to the NaOH control (42.4 ± 1.5 g/100 g).

Industrial Uses of Hydrated Lime Industrial Ingredient ...

Mar 01, 2021  The specific hydrated lime depends on the catalysts utilized and the type of quicklime. High calcium hydrated lime contains 72%-74% calcium oxide; dolomitic hydrated lime contains 46%-48% calcium oxide and 33%-34% magnesium oxide; and dolomitic hydrated lime (pressurized) combines 40%-42% calcium oxide with 29%-30% magnesium oxide.

Jul 07, 2017  Hydrated lime is also sometimes called slaked lime. For the flue gas desulphurization, the characteristic of hydrated lime requires enhanced average fineness, higher surface area, and higher volume of the pores. The hydration reaction is chemically simple but it is strongly exothermic, with a heat generation of around 276 kcal/kg of CaO.
