Pump Materials for Wet Flue Gas Desulfurization | Pumps ...

Dec 28, 2018· A cement factory in Texas was among the first in the U.S. to install wet flue gas scrubbers in order to reduce the sulfur dioxide emissions. This is a demanding application for pumps because the gypsum slurry that "scrubs" the gas is highly abrasive and corrosive. Special pump systems with housings and impellers made of mineral cast proved to be an ideal solution for this specific …

Wet Flue Gas Desulfurization with Seawater

The core of seawater FGD engineering is the absorber that separates SO2 from flue gas. A spraying tower is used for this purpose, with the flue gas flowing from bottom to top. The absorbent seawater is evenly sprayed via several spraying levels to ensure ideal conditions for mass transfer with the gas flow.

Flue Gas Desulfurization Wastewater - Bothell, WA

from the flue gas they generate. Over 85% of flue gas desulfurization (FGD) systems use wet scrubbers that employ a limestone-forced-oxidation process, spraying slurry over flue gas to convert gaseous sulfur dioxide to calcium sulfate particulates. Once the level of suspended solids in the slurry reaches a certain limit, it is purged

Flue Gas Desulphurisation Plant - Gas and electricity supplier

Before the flue gas reaches the absorber tower, it passes through a heat exchanger. The purpose of the heat exchanger is to cool the flue gas into the FGD to 90 degrees C. This heat is then used to reheat the cooled, treated flue gas as it passes back through the heat exchanger where it is reheated to above 80 degrees C to give it the buoyancy

Flue gas desulphurisation system | KSB

In a flue gas desulphurisation system (FGD), sulphur compounds are removed from the exhaust emissions of fossil-fuelled power stations.This is done by means of an industrial process through the addition of absorbents. This can remove up to 95 % of the sulphur dioxide from the flue gas, since the current threshold value for SO 2 in the EU is 200 mg/Nm 3 (Nm 3 = normal cubic metre).

Flue gas desulfurization equipment - Lenntech

Flue gas desulfurization equipment. The boiler is the furnace where fossil fuels as coal and wood moistures are burned. The design temperature to operate the furnace is ideally above the meting point of the ash, as the buildup of hard slag increases maintenance costs.

Ammonia-based FGD

Efficient ammonia desulfurization (EADS) is the core service of JET. From the reaction between NH 3 and SO 2, it is capable of efficiently removing SO 2 from the exhaust gas and also producing valuable fertilizer, ammonium sulfate. Compared to the most widely used limestone-gypsum process in boiler flue gas treatment, the EADS is more efficient, consumes less power, and produces no waste water ...
