Get this from a library. Trace element characterization and removal from coal and coal wastes. [Paul Wagner; Los Alamos Scientific Laboratory.; United States. Department of Energy.]. Book Description Trace Elements in Coal and Coal Combustion Residues focuses on trace metal chemistry of coal and coal combustion residues.
Special emphasis is placed on management of coal combustion residues in electric power plants and the influence of coal and associated residues on soils, plants, water, and animals. Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal.
The book first discusses the origin of trace elements in Edition: 1. These data, when viewed in the context of our past observations that the concentrations of trace elements released by a coal waste are related to the acid-generating tendency of that waste, demonstrate that even low-sulfur wastes have the potential of acting as sources of trace elements in amounts that are of potential environmental concern.
TASK PROGRESS DESCRIPTION TASK 1-ENVIRONMENTAL CONTROL TECHNOLOGY FOR TRACE ELEMENTS IN THE DRAINAGE FROM HIGH-SULFUR COAL PREPARATION WASTES Subtask —Assess Technology to Prevent Trace Element Releases From Newly Produced Refuse Materials The purpose of this subtask is to investigate in the laboratory the options available for treating high-sulfur coal.

Estimating the TE concentrations of these waste streams is essential to selecting pollution controls and estimating emission reduction benefits. This work introduces a generalizable mass balance model for estimating TE mass flow rates in CFPP waste streams Cited by: 1.

Trace elements are present in coal ash because the parent coal from which the ash is derived also contains trace elements. as a result of natural formation processes.
During combustion, most trace elements in the parent coal are retained in the residual coal ash and are concentrated in the smaller volume of the ash compared to the original by: 5. Besides the major (>1%) and minor (–1%) elements in coal, elements such as As, Ba, Cr, Mn, Mo, Sb, Th, U, V and others occur commonly as trace elements (waste products from coal combustion are generated mostly from the inorganic matter of by: Coal gangue is one of the largest industrial residues.
It has high ash content, low carbonaceous content, and heating value. Meanwhile, it has some trace elements. Large quantities of coal gangue cause serious environmental problems by polluting the air, water, and soil as well as occupying a tremendous amount of by: 1.
Trace elements can have profound adverse effects on the health of people burning coal in homes or living near coal deposits, coal mines, and coal-burning power plants. Trace elements such as arsenic emitted from coal-burning power plants in Europe and Asia have been shown to cause severe health problems.
Trace element characterization of coal wastes: fifth annual progress report Author: R C Heaton ; Industrial Environmental Research Laboratory (Research Triangle Park, N.C.). Trace elements such as mercury, arsenic and selenium present in coal are known to be of concern for public health.
Coal-fired power plants have resulted in emission of Cited by: The purpose of this corit'erence was to present current knowledge on the source, pathways, behavior and effects of trace elements in soils, waters, plants and animals.
In addition, the book also includes invited research papers from scientists who have done significant research in the area of coal and coal combustion byproducts. Trace Elements in Coal and Coal Combustion Residues focuses on trace metal chemistry of coal and coal combustion residues.
Special emphasis is placed on management of coal combustion residues in electric power plants and the influence of coal and associated residues on soils, plants, water, and by: This book is intended primarily for coal scientists and technologists involved in environmental aspects of trace elements during the mining of coal, its beneficiation and usage, especially for power generation, and for regulatory bodies.
It is considered to be suitable for relevant postgraduate courses. Mobility of trace elements from coal and combustion wastes Article (PDF Available) in Fuel 75(7) May with 69 Reads How we measure 'reads'.
Abstract. Coal will be a major energy source in the United States and in many other countries well into the 21st century. Although coal is composed predominantly of organic matter, inorganic constituents in coal commonly attract more attention and can ultimately determine how the coal Cited by: The mineral wastes produced by coal cleaning contain in abundance of toxic or potentially harmful trace elements.
Although it has been well established that many of these toxic elements are present in the drainages from coal waste dumps, little is known about the quantities released into the environment from this source. Unfortunately, this book can't be printed from the OpenBook.

To better investigate the characteristics and sources of trace elements (TEs) in PM in urban Beijing, a 1‐year hourly observation was continuously made using an online multi‐element analyzer from 1 June to 31 May The average concentrations of 14 individual TEs ranged from (V) to ng/m 3 (K).
The occurrence levels of most TEs of interest in Beijing Cited by: 1. Environmental impacts of potentially toxic trace elements from coal fly ash are controlled in part by the mineralogy of the ash matrix and the chemical speciation of the trace elements.
Our objective was to characterize the chemical and mineralogical composition of fly ash samples that are pertinent to the release of coal ash from a containment area at the Tennessee Valley Cited by: Unique in presenting comprehensive and multidisciplinary information of the key aspects of trace elements research in a digestible form, this book is essential reading for the novice and expert in the fields of environmental science, analytical chemistry, biochemistry, materials science, pharmaceutical science, nutraceutical, and pharmaceutical.
Around 70% of fly ash produced worldwide is disposed of as waste; this waste is highly contaminating because of toxic trace elements contained within coal, which accumulate as the organic content of the coal is eliminated.
