Limestone Slurry for FGD

Application: Environmental regulations require power plants to employ flue gas desulphurization (FGD) to control sulfur dioxide (SO2) emissions. Limestone scrubbing is the method of choice for coal-fired plants, yielding efficiencies of 90% - 98%. SO2 is neutralized by direct contact with limestone slurry in an absorption tower.

Investigation on Mercury Reemission from Limestone-Gypsum Wet Flue Gas Desulfurization Slurry …

 · Abstract Secondary atmospheric pollutions may result from wet flue gas desulfurization (WFGD) systems caused by the reduction of Hg 2+ to Hg 0 and lead to a damping of the cobenefit mercury removal efficiency by WFGD systems. The experiment on Hg 0 reemission from limestone-gypsum WFGD slurry was carried out by changing the operating conditions …

Advanced Process Control for Optimizing Flue Gas Desulfurization

 · Sulfur dioxide (SO 2) contained in the flue gas is absorbed by a limestone slurry sprayed from the header at the top of the absorber. 1. Limestone scrubbing flow diagram.

Liquid-to-gas ratio

An important parameter in wet scrubbing systems is the rate of liquid flow. It is common in wet scrubber terminology to express the liquid flow as a function of the gas flow rate that is being treated. This is commonly called the liquid-to-gas ratio (L/G ratio) and uses the units of gallons per 1,000 actual cubic feet or litres per cubic metre (L/m 3).

Minimal flow rate ratio of slurry and gas in lime/limestone flue gas …

The lime/limestone scrubbing process is the most commonly used method for reduction of the SO2 concentration in flue gases. The process requires a large amount of energy for slurry recycling in the scrubber and therefore careful control of the ratio between slurry and gas flow rate is required. Calculation of the minimum ratio of slurry to gas flow rate (L/V) m under …

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.
