Utilizing a 2:1 water-to-lime ratio, the A-758 unit slakes lime as paste which provides a number of benefits over the more traditional 4:1 water-to-lime or slurry slaking process. This includes less power, faster slaking, a smaller footprint and, most importantly, a more reactive lime slurry solution. Saves Power

For example, for SO2 capture with ground limestone in wet FGD, much of the coarser particles never react with gasses because of a short contact period and these particles are basically wasted. For limestone to react with SO2 gas, there should be some dissolution of limestone so that it can ionize. Fine pulverization generally improves the rate of …

Lime Slaking is the process of mixing quicklime (calcium oxide, CaO) with water to form hydrated lime (calcium hydroxide CaOH 2), using excess water to produce a slurry. The reaction of quicklime and water is exothermic and will produce 491 BTUs per pound of CaO and form 1.32 pounds of calcium hydroxide.

Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 -> Ca(OH)2) by mixing with water. Lime slaking is an exothermic process which generates heat and creates steam. Slaked or hydrated lime is often used in mining and process industries for raising pH or neutralising acidic solutions.

Lime is the most widely used reagent in water treatment applications. It is supplied in two forms: quick lime: CaO; slaked (or hydrated) lime: Ca(OH) 2. Warning: in both cases, these reagents will contain between 4 and 20% of solid impurities (CaCO 3, SiO 2 …). These impurities must be removed before the product is used. quick lime slaking ...
