Industrial Chemistry
This collection presents to the reader a broad spectrum of chapters in the various branches of industrial chemistry, which demonstrate key developments in these rapidly changing fields.
Membrane Gas Separation
Gas separation membranes offer a number of benefits over other separation technologies, and they play an increasingly important role in reducing the environmental impacts and costs of many industrial processes. This book describes recent and emerging results in membrane gas separation, including highlights of nanoscience and technology, novel polymeric and inorganic membrane materials, new membrane approaches to solve environmental problems e.g. greenhouse gases, aspects of membrane engineering, and recent achievements in industrial gas separation. It includes: Hyperbranched polyimides, amorphous glassy polymers and perfluorinated copolymers Nanocomposite (mixed matrix) membranes Polymeric magnetic membranes Sequestration of CO2 to reduce global warming Industrial applications of gas separation Developed from sessions of the most recent International Congress on Membranes and Membrane Processes, Membrane Gas Separation gives a snapshot of the current situation, and presents both fundamental results and applied achievements.

Fundamental Understanding of Mercury Removal from Coal Combustion
Coal-fired power plants are a major anthropogenic source of worldwide mercury (Hg) emissions. Since mercury is considered to be one of the most toxic metals found in the environment, Hg emissions from coal-fired power plants is of major environmental concern. Mercury in coal is vaporized into its gaseous elemental form throughout the coal combustion process. Elemental Hg can be oxidized in subsequent reactions with other gaseous components (homogeneous) and solid materials (heterogeneous) in coal-fired flue gases. While oxidized Hg in coal-fired flue gases is readily controlled by its adsorption onto fly ash and/or its dissolution into existing solution-based sulfur dioxide (SO2) scrubbers, ...

Processing and Utilization of High-sulfur Coals III
This volume is a collection of peer-reviewed articles providing a summary of the most recent accomplishments by many of the leaders of high-sulfur coal research and development. Improvements in coal cleaning technology by application of either physical, chemical, or biological processes, and new developments in both the froth flotation and oil agglomeration methods of cleaning are reported. Innovative electrostatic and aerodynamic methods are described for cleaning coal, and progress is noted in the development of coal desulfurization by either caustic leaching, oxidative leaching, microbial treatment, or low-temperature pyrolysis. Papers also included in this book concern the capture of sulfur oxides either during or following the combustion of coal; sorbent characterization and the effects of different factors and/or additives on sorbent utilization; the capture of sulfur oxides in various types of combustion systems, including pulverized coal, slagging, fluidized bed and magnetohydrodynamic systems. Recent technical developments are reported for sorbent injection in flue-gas ducts as a means of capturing sulfur oxides.
