Minor and trace element emissions from post-combustion CO2 capture from coal: Experimental and equilibrium calculations

Indoor Emissions from Household Combustion of Coal

Coal is a highly variable fuel, which ranges from high heating-value anthracite through various forms of bituminous coal to intermediates in coal formation, viz. lignite and peat. Each of these types of fuel can contain different levels of moisture, non-combustible inorganic material (ash), sulfur, and sometimes significant levels of other impurities, e.g. arsenic, fluorine, lead and mercury. R...

Non-co2 Emissions from Stationary Combustion

All these gases are addressed by the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Guidelines). The technical approach in estimating CO2 emissions is relatively simple and the accuracy level high since the CO2 emission factors are mainly a function of the fuel properties, which are generally well addressed by most countries. The non-CO2 emissions however are closely...

Advanced Solvent for CO2 Capture and Separation Technology for CO2 Sequestration to Enhance Utilization and Reduce Emissions from Wyoming Coal

Systems Analysis of Ionic Liquids for Post-combustion CO2 Capture at Coal-fired Power Plants

The main objective of this study is to investigate the feasibility and costs of ionic liquid (IL)-based CO2 capture systems at pulverized coal-fired (PC) power plants. The IL selected for this assessment is trihexyl(tetradecyl)phosphonium 2-cyanopyrrolide ([P66614][2-CNpyr]), achieving a 1:1 and reversible chemical reaction between [2-CNpyr] and CO2. A multi-stage equilibrium-based modeling fra...

Mass Release of Trace Elements from Coal Combustion By-Products

More than 100 million short tons of coal combustion by-products (CCB) are generated annually. More stringent environmental regulations and increasing costs will discourage placement in landfills, encouraging increased utilization and the development of new uses for CCB. However, the potential release of trace elements from CCB is a continuing environmental concern. A study at the Federal Energy...
