Influence of wet flue gas desulfurization on the pollutants monitoring in FCC flue gas
Environmental Science and Pollution Research, 2021Fluid catalytic cracking (FCC) unit emits a large amount of flue gas, which is a major concern of environmental protection supervision. Wet flue gas desulfurization (WFGD) technologies have been widely used to control the emissions of SO2 in refineries. In this study, stack tests for pollutants emission of a typical FCC unit were conducted.

Electrochemical membrane process for flue gas desulfurization
AIChE Journal, 1994AbstractA flue gas desulfurization process being developed for coal‐fired power plants removes and concentrates sulfur oxides (SOx). The key element is an electrochemical cell using a sulfur oxide selective membrane. It achieves 90% sulfur oxide removal with near 100% electric current efficiency.Recent research has focused on improving the structure of

Economic Dispatch for Flue Gas Desulfurization
Journal of Energy Engineering, 1983An economic dispatch model is developed to simulate the daily load dispatch operations of a power system. The model has been used to account for the operation of various flue gas desulfurization (FGD) systems and their impacts on power system economic dispatch pattern and SO2 emissions.

Flue Gas Desulfurization (FGD) Residue
1999Flue Gas Desulfurization (FGD) residue is produced when SOx and NOx are removed from gases produced during the combustion of coal. This by-product is becoming increasingly significant with more stringent air quality standards, and increasing fossil fuel consumption. FGD residues vary widely in their composition; ranging from products composed mainly of

Flue Gas Desulfurization: The State of the Art
Journal of the Air & Waste Management Association, 2001Coal-fired electricity-generating plants may use SO2 scrubbers to meet the requirements of Phase II of the Acid Rain SO2 Reduction Program. Additionally, the use of scrubbers can result in reduction of Hg and other emissions from combustion sources. It is timely, therefore, to examine the current status of SO2 scrubbing technologies.

Liquid membranes for flue gas desulfurization
Journal of Membrane Science, 1990Abstract A number of aqueous liquid membranes were tested to study their efficacy in flue gas desulfurization. A simulated flue gas containing SO 2 , CO 2 , O 2 , N 2 and moisture was used as the feed gas. The candidate membrane liquids were immobilized in microporous polypropylene Celgard® 2400 films. Permeabilities of the above species through the

Seawater Flue Gas Desulfurization and Post-Desulfurization Seawater Recovery
Advanced Materials Research, 2011Huge storage tanks of Vinyl chloride monomer (VCM) are often regarded as major hazard installation because VCM is such a kind of flammable, explosive and toxic gas that leakage of liquid VCM would induce fire, explosion and toxic accidents. In this paper, index system of the safety of VCM storage tanks was established by analyzing four main factors ...

Utilization of residuals from flue gas desulfurization
Environmental Progress, 1986AbstractDiverse large‐scale sources of FGD gypsum, the plentiful waste by‐product from SO2 emissions cleanup in major industrial countries, are characterized in terms of properties including crystal form and contained impurities that affect commercial usability.

Flowable Fill Using Flue Gas Desulfurization Material
Journal of ASTM International, 2004Abstract Flowable fills are an effective and practical alternative to commonly used compacted earth backfills. Flowable fill is a cementious material, commonly a blend of cement, fly ash, sand, and water, that does not require compaction, may be self-leveling at time of placement, may harden quickly within a few hours, and can be ...
