What is fluid gas desulfurization?

Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) 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 treated before disposal.

How does flue gas desulfurization work?

How does it work? The FGD technology is based on a chemical reaction that occurs when the warm exhaust gases from the coal-fired boiler come into contact with limestone. This reaction removes 92% of the sulphur dioxide from the flue gas and converts the limestone into Calcium Sulphite.

What is the purpose of flue gas desulfurization?

Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from flue gases produced from industrial combustion at petrol refineries, chemical manufacturing industries, mineral ore processing plants, and power stations to name a few.

What gas does desulfurization remove?

sulfur dioxide
Flue gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from flue gases produced from industrial combustion at petrol refineries, chemical manufacturing industries, mineral ore processing plants, and power stations to name a few.

How is flue gas desulfurization used in 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, and from the emissions of other sulfur oxide emitting processes such as waste incineration.

How is the cost of desulfurization calculated?

Desulfurization cost (DC) is defined as the cost of sweetening one thousand standard cubic feet (MSCF) natural gas. Aspen Plus process simulations are used to calculate raw material and utility requirements, and equipment sizes for each process.

When did desulfurization of furnace exhaust gases start?

Methods of removing sulfur dioxide from boiler and furnace exhaust gases have been studied for over 150 years. Early ideas for flue gas desulfurization were established in England around 1850. 2 from a single site began to concern the public. The SO 2 emissions.

How does the converging section of gas desulfurization work?

The converging section accelerates the gas stream to high velocity. When the liquid stream is injected at the throat, which is the point of maximum velocity, the turbulence caused by the high gas velocity atomizes the liquid into small droplets, which creates the surface area necessary for mass transfer to take place.
