Coal Processing and Pollution Control; Thomas F. Edgar

This book provides a detailed examination of coal processing technologies and the associated methods for controlling environmental pollution. It reflects growing concerns in the late 20th century about the environmental impact of coal utilization and the need for cleaner energy practices.

The text begins with an overview of coal characteristics, including composition, classification, and properties that influence processing and combustion behavior. It then discusses various coal preparation techniques, such as:

Crushing and grinding
Washing and beneficiation to remove impurities (e.g., sulfur, ash)
Size classification and handling

A central focus of the book is on pollution control, particularly in relation to coal combustion and industrial use. Key topics include:

Air pollution control: reduction of sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and particulate emissions
Flue gas treatment: scrubbers, electrostatic precipitators, and filtration systems
Solid waste management: handling and disposal of ash and other byproducts
Water pollution considerations: treatment of wastewater from coal processing

The book also examines process design and optimization, integrating chemical engineering principles to improve efficiency while minimizing environmental impact.
