Flue gas CO₂ capture using electrochemically mediated amine regeneration
… (EMAR) process for the capture of CO₂ from flue gas. The absorption step in the EMAR process is the same as in the widely used amine process, but the desorption step is accomplished electrochemically as opposed to a thermal swing. The EMAR process has several potential advantages over …

Evaluation of modified dry limestone process for flue gas desulfurization
… of the Modified Dry Limestone Process (MDLP) for flue gas desulfurization. Two types of limestone, one calcitic and one dolomitic, were used. These materials were characterized by ICP analysis, X-ray diffraction, optical microscopy, SEM, and electron microprobe before and after reaction. …

A Study of Hg Adsorption and Reactions in a Flue Gas
… Hg adsorption and oxidation in a simulated flue gas system were studied. Density functional theory using B3LYP paramerization were used to calculate binding energies, thermodynamic parameters, and kinetic constants. Binding energy calculations show that HCl, SO<sub>2</sub>, or NO<sub>2</sub> …

Thermal swing membrane based method for CO2 capture from flue gas
Carbon dioxide, a greenhouse gas and a major contributor to global warming, is released in large amounts by flue gases. To limit climate change, such CO_2 emissions have to be reduced, CO_2 captured and sequestered. Conventional monoethanolamine (MEA)-based absorption techniques are costly due to …

Heat exchanger design for thermoelectric electricity generation from low temperature flue gas streams
… generator to convert low grade waste heat in flue gas streams to electricity. The NTU-effectiveness method, exergy, and thermoelectric relations were used to guide the modeling process. The complete system design was optimized for cost using the net present value method. A number of …

Mercury Transportation in Soil Using Gypsum from Flue Gas Desulphurization Unit in Coal-Fired Power Plant
… mercury flux in soil amended by gypsum from flue gas desulphurization (FGD) units of coal-fired power plants. There are two phases of this research, including field and greenhouse studies. Previous studies indicate that FGD gypsum could increase corn yield, but may lead to more mercury uptake …

Cycle Scheduling and Design of Pressure Swing Adsorption (Psa) Cycles For Carbon Dioxide Capture From Flue Gas
… goal is to capture 90% of the CO2 from stack or flue gas, concentrate it to over 95 vol%, and sequester it somewhere in the Earth. The goal of this dissertation is to discuss and present the results obtained while developing a viable PSA process for CO2 capture, based on experiments and process …

Investigation into methods for the calculation and measurement of pulverised coal boiler flue gas furnace exit temperature
The boiler flue gas furnace exit temperature (FET) is a key operating parameter of coal fired steam boilers. From the design perspective, the FET is vital for materials selection and sizing of heat transfer surfaces. From an operating perspective, it is a major indicator of the rate of combustion …

Thermodynamic and Kinetic Study of Carbon Dioxide and Mercury Removal from Flue Gas in Coal Combustion Power Plants
… of CO<sub>2</sub> and Hg from coal combustion flue gas requires additional air pollution control devices that can only do a single task . To reduce the cost, a new approach to capture both CO<sub>2</sub> and Hg from coal combustion flue gas in an integrated adsorbent system was discovered. In …

Hydrogeological and hydrogeochemical evaluation of a proposed flue gas cleanup dry waste disposal pit near Beulah, North Dakota
… (MDU) is located near Beulah, North Dakota. Flue gas cleanup {FGC) dry waste is generated by the facility in the conversion of coal to electricity. MDU submitted a permit application to the North Dakota State Department of Health {NDSDH) to dispose of FGC dry waste in a strip-mined area 1.6 …

An On-line Test for Polycyclic Aromatic Hydrocarbons in the Flue Gas from Coal Combustion in an FBC System
Polycyclic Aromatic Hydrocarbons (PAHs) are environmental pollutants that have received considerable attention because of their carcinogenic and mutagenic effects. Due to the extensive amount of data suggesting the hazards of these compounds, 16 PAHs are on the Environmental Protection Agency (EPA) …

Liming Characteristics of a High-Calcium, Dry Flue Gas Desulfurization By-product and its Effects on Runoff Water Quality
<p>In 2013, only 37% of the 32 million Mg of flue gas desulfurization (FGD) by-products generated in the United States were reused beneficially. If FGD by-products could be used as a beneficial soil amendment, millions of megagrams may be diverted away from surface impoundments and landfills. The …

Impact of Surface Application of Flue Gas Desulfurization Gypusum on Infiltration, Phophorus Behavior, and Total Sulfur in a Previously Manured Coastal Plain Soil
Flue gas desulfurization (FGD) gypsum was surface-applied on a poorly drained cultivated Coastal Plain soil in Maryland containing excessive amounts of plant-available phosphorus (P). Using a constant head double-ring infiltrometer, a field experiment indicated a slight increase in final …
