However, limestone B direct desulfurization conversion was relatively higher than limestone C and limestone D. It is possible that higher inert components in the limestone from the formation of CaSO 4, such as SiO 2, Al 2 O 3, and Fe 2 O 3, interfered with pore clogging, and addition desulfurization reactions of MgO occurred.

Wet Flue Gas Desulfurization with Lime/Limestone Slurry

In wet flue gas desulphurisation, open spray tower absorbers have prevailed which are divided into two principal zones. These are the absorption zone exposed to the flue gas and the absorber sump, in which the limestone slurry is trapped and collected. To prevent deposits in the absorber sump, the slurry is suspended by means of mixing mechanisms.

Desulfurization Limestone Powder Processing

Power plant using LIFAC dry fuel gas desulfurization technology, with limestone powder as SO2 absorption agent, desulfurization process is divided into two stages: furnace desulfurization and activation desulfurization in the vessel. Thus, combines the advantages of furnace desulfurization and spray drying desulfurization.

Three Factors Affect Limestone Desulfurization Efficiency

In the desulfurization process of powder plant, limestone powder is the most commonly used desulfurizing agent. The limestone desulfurization efficiency will directly affect the quality and efficiency of powder production process. And there are several factors that affect limestone desulfurization efficiency in powder plant.

Desulfurization using limestone during sludge

01-08-2020  Incineration of sludge can be an effective method to minimise waste whilst producing useful heat. However, incineration can cause secondary pollution issues due to the emission of SO 2, therefore a set of experiments of sludge incineration in a bubble bed furnace were conducted with limestone addition to study desulfurization of sludge incineration flue gas.

Neither lime nor limestone dissolves well in water and therefore, both are pumped in slurry form to the scrubber tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. Unless

Flue Gas Desulfurization by Limestone and Hydrated lime is used as sorbent material instead of limestone. It is known that, the hydrated lime possesses higher desulfurization capacity than limestone due to its higher solubility and higher alkalinity in slurry and better reactivity with SO2 at low temperature (Ma et al., 2000; Özyuğuran et al., 2006).
