    Approximately 85% of the flue gas desulfurization units installed in the US are wet scrubbers, 12% are spray dry systems, and 3% are dry injection systems.

This article begins with a discussion on the components and importance of flue gas desulfurization (FGD) technology used in power plant for pollution control.

It further discusses the corrosion problems encountered in different operating zones of FGD system and the major forms of corrosive attack encountered in those zones, including crevice corrosion, pitting corrosion. Corrosion of flue gas desulfurization (FGD) scrubbing equipment is one of several critical problems facing both the power industry operating these units and the engineer-ing firms that have to select materials of construction for the specific processes.

The various processes and the status of flue-gas desulfurization technology were discussed at the. Get this from a library. Corrosion in flue gas desulfurization systems: proceedings of Corrosion/83 Symposium on Performance of Construction Materials in Flue Gas Desulfurization Systems [and] Corrosion/84 Symposium on Materials Evaluation and Environmental Effects on Corrosion in Flue Gas Desulfurization Systems.

[G H Koch; N G Thompson; National Association of Corrosion. That is, on one hand, simulation experiments were conducted in laboratories for performances assessment of the materials intended for use in wet FGD systems, such as the pitting and uniform corrosion behaviors of one FeAl alloy steel in the wet desulfurization unit of a natural gas purification master plant [28], Cited by: 1.

Flue Gas Desulfurization (Acid Gas Removal) Systems Goal To familiarize you with the operation of flue gas desulfurization (FGD) systems that use a scrubbing liquid to absorb SO2 present in the exhaust gas stream.

Objectives At the end of. new corrosion resistant alloys were developed and used for the FGD systems. Few of these alloys are – duplex stainless steel, IncoloyInconelHastelloy C and Hastelloy C Considering the absorber inlet, the hot flue gas travels through the sulfuric acid dew point, causing the condensation of warm and concentrated sulfuric acid.

Flue-gas desulfurization (FGD) is the removal process of sulfur dioxide (SO 2) from flue gas emissions, often chemically. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.

SO 2 and O 2 are typically measured at the inlet and outlet of the flue gas desulfurization system to control the lime dosing and insure the removal efficiency of this key pollution control system. The GM32 in-situ gas analyzer measures SO2 fast and under process conditions without complicated gas transport, the ZIRKOR measures O2 with a corrosion resistant probe.

wet systems were employed for flue gas desulfurization (FGD). These systems reduced flue gas temperatures to below acid dew point conditions. Concerned about the prospect of ductwork exposed to a saturated, acid-rich environment, most utilities turned to stack gas reheat (SGR) to increase flue gas temperatures.

This study investigated the prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant. The performance analysis and comparative studies of six materials for the prevention of stack corrosion were investigated.

The ion chromatography analysis showed the acid condensation contained fluoride, chloride, Cited by: 1.

This paper combined with the actual case of flue gas desulfurization (FGD) system in cement Plant, analyzes the corrosion environment in each area of the FGD system, and selects appropriate anticorrosive materials for different corrosion environment, so as to provide operating experience and reference for the safe, stable and efficient operation of the FGD system.

Corrosion problems and materials selection for emissions control equipment can be difficult because of varied corrosive compounds present and the severe environments encountered.

This article discusses the selection of materials for construction of flue gas desulfurization systems. Pharos is a tool to help scientists, researchers, and product innovators identify problematic chemicals and collaborate to find safer Size: KB.

The most commonly required desulfurization process is in natural gas, but it is also required for flue gas, coal and oil. Sulfur in crude oil, natural gas, process gas and natural gas liquids (LNG) may take many forms, including hydrogen sulfide (H 2 S), carbonyl sulfide (COS), sulfur oxides (SOx) and the whole family of mercaptans.

One of the main problems to put flue-gas desulfurization plants out of operation is corrosion. Severe problems in FGD installations are caused when condensates of acids are formed, which accelerate pitting and crevice corrosion, particularly in. To reduce the influence of flue gases, and specifically the production of sulfuric acid (H 2 SO 4) and HCl in the surrounding atmosphere, on human health and the environment, a technology named flue gas desulfurization (FGD) is applied.

Briefly, the flue gas flows into the FGD system through a duct where they are absorbed and removed by the Cited by: An aggressive form of corrosion has been found in relatively new flue gas desulfurization systems installed in U.S.

coal-fired plants. In response, EPRI has launched a rapid-response project to investigate the root cause of the corrosion. Flue Gas Desulfurization (FGD) systems are a critical component for any coal-fired electric generating unit that needs to meet regulatory emissions requirements.

But due to the corrosive nature of the product that is processed, corrosion can compromise structural integrity. Provides guidance in selecting and applying Flue Gas Desulfurization (FGD) system linings in power generation facilities.

Covers four generic classes of available lining materials used to protect equipments from corrosion in wet scrubbing FGD systems. Also discusses the application of protective linings to steel, corrosion-resistant alloys, and.Corrosion in FGD systems is an extremely important concern associated with wet scrubbers.

After the hot SO 2-containing gasses from the boiler are quenched in a scrubber unit, the exiting flue gas is now saturated with water but still contains residual SO 2. The SO 2 reacts with pyritic iron and is converted to SO Size: 37KB.The flue gas volume of a cement production line in plant A isNm 3 /h.

After flue gas desulfurization (FGD) modification, the temperature of flue gas at the outlet of the desulfurization tower is 50˚C. When the flue gas discharges from the direct chimney, the “white smoke” appears and accompanied by “gypsum rain”.Author: Mengyu Wang.
