Global regulation changes demand reduction of the emissions from power plants. Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO 2) from exhaust flue gases of fossil-fuel power plants, as well as from the emissions of other sulfur oxide emitting processes.When using a wet FGD scrubbing process, wastewater is generated, which must be …

Turndown of the unit is accomplished by reducing both liquor flow and gas speed, although when the load drops below about 80 percent of capacity, flue gas is recirculated to maintain gas velocity. During a period of 45 days of service, the operation was typically at 55 to 70-MW in the day, about 30 to 35 at night, and about 3-MW over the weekend.
Get PriceFlue gas (sometimes called exhaust gas or stack gas) is the gas that emanates from combustion plants and which contains the reaction products of fuel and combustion air and residual substances such as particulate matter (dust), sulfur oxides, nitrogen oxides, and carbon monoxide (Table 3.7).When burning coal and/or waste materials, hydrogen chloride and hydrogen fluoride may be present in the ...

CONCAWE has studied costs of applying regenerative flue gas desulphurization in European refineries based on actual experience from the Wellman-Lord process in one refinery. It has been necessary to relate the situation there to the more general European refinery situation in order to identify cost influencing items.

The most commonly used method of flue gas desulphurization is the spray scrubber using limestone as the neutralising agent. Nozzles create the reaction surface. Sulphur in the flue gas reacts with the lime (Sulfite-Sulfate precipitates with calcium as gypsum). The reaction product gypsum (the primary ingredient of plasterboard is eliminated.
