    Laboratory Testing with a Simulated Flue Gas. A setup that included various compressed gas tanks and a gas mixing unit, a 60 L Teflon-coated tank scrubber, pH controller and slurry pump, feed slurry container, external band heater, gas condenser/cold trap, Hg gas analyzer, and SO 2 gas analyzer, was used to evaluate the performance of the baseline limestone sample and the two lime sludge Author: Seyed A. Dastgheib, Justin Mock, Hafiz H. Salih, Craig Patterson. A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a MW scale in

    Ducon produces high-efficiency absorbers capable of up to 98% sulfur dioxide removal with limestone. All designs consume minimal power and limestone. FGD Scrubber Material - Material Description ORIGIN The burning of coal produces sulfur dioxide (SO 2) Clean Air Act and subsequent amendments regulate SO 2 emissions from burning coal. Coal fired power plants installed flue gas desulfurization (FGD) technology for reducing SO 2 emissions. The two most common scrubber technology used today are wet or dry systems.

Lime/limestone flue gas desulfurization inspection and performance evaluation manual. [E R Kirshnan; Air and Energy Engineering Research Laboratory.;].

The manual--on wet nonregenerable lime/limestone flue gas desulfurization (FGD) systems--is intended to guide Federal and State regulatory personnel concerned with the inspection and permitting of FGD systems for coal-fired steam electric generators in the U.S. It is a working document for someone who periodically inspects power plants to ensure their compliance with emission standards.

The complete report, entitled "Lime/Limestone Flue Gas Desulfurization Inspection and Performance Evaluation Manual," (Order No. PB /AS; Cost: $, subject to change} will be available only from: National Technical Information Service Port Royal Road Springfield, VA Telephone: The EPA Project Officer can be.

The intent of the manual is to provide inspectors from Federal and state environmental agencies with information regarding the problems that plague lime/limestone slurry flue gas desulfurization (FGD) systems that will aid them in their inspections and performance evaluations of these systems with respect to compliance with the emission standards that have evolved since the.

After fly ash removal, the flue gas (seen in Figure 1) is bubbled through the scrubber, and the slurry is added from lime or limestone reacts with the SO 2 in the flue gas to create insoluble calcium sulfite (CaSO 3) as in the equations below. Limestone: CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g) Lime: Ca(OH) 2 (s) + SO 2 (g.

Project Summary Economic Evaluation of Limestone and Lime Flue Gas Desulfurization Processes T.A. Burnett, C.D. Stephenson, F.A. Sudhoff, and J.D. Veitch The preliminary-grade economics (accuracy: 15%, +30%). A detailed process model of the wet limestone flue gas desulfurization system has been presented.

This model can be used to calculate indispensable parameters for estimating costs and next to minimize capital and operating costs. The process model describes most important stage of SO2 removal running in an absorber and a holding tank.

It includes absorption of sulfur dioxide, oxidation of SO3 Cited by: Recent studies in oxy-combustion conditions have presented new questions about the use of limestones, because the differences in the firing atmosphere of the fuel significantly affect the SO 2 retention process.

It was written as an aid to utility engineers involved in the design, specification, project management, and operation of lime-based, flue gas desulfurization (FGD) systems. Dolomitic lime-stone, CaCO3 • MgCO3, undergoes similar reactions to form analogous dolo-mitic compounds.

The dolomitic hydrated lime can be further hydrated to Ca(OH)2 • Mg(OH)2 under pressure. Although this material was used in some related studies, no specific references to it are included in this paper. Flue Gas Desulfurization Technologies.

US EPA, Flue Gas Desulfurization Inspection and Performance Evaluation, Report No. EPA///, US Environmental Protection Agency, Washington, DC, Google Scholar Cited by: In Part II of this work, the feasibility of lime sludge utilization in the flue gas desulfurization (FGD) process was evaluated by conducting laboratory-scale tests with a simulated flue gas at a flow rate of L/min (LPM).

3 Eight lime sludge samples and a baseline limestone sample were evaluated for their performance capability to remove SO. Flue Gas Desulfurization is a widely adapted technology for removing sulfur dioxide from the exhaust flue gas in coal- and oil-fired power plants.

In the “wet limestone-gypsum” form of FGD, an aqueous slurry of finely ground limestone is introduced into an absorber tower and contacted with the flue gas. Megawatts (MW) and whose Flue Gas Desulfurization devices have been operating for at least 5 years. An analysis is made of the capital and annual costs of these systems using a comparison of four main processes: lime, limestone, dual alkali and sodium carbonate scrubbing.

Often, the technology is unfamiliar and the array of alternatives extensive.This reaction is of great interest in the study of wet flue gas desulfurization processes.

In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 - 2H 2 O).

Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.
