Sulfur, Energy, and Environment


Book Description

Sulfur, Energy, and Environment is a guide to the properties of sulfur; its three important compounds; and a review of the production, use, and recovery of sulfur in relation to energy production and environmental protection. After a brief introduction to the history of sulfur, the chemical properties of the element and some important compounds are reviewed, using common analytical methods. Sulfur is a strategic chemical in many modern applications and may make headway into high-volume non-chemical uses as it is being modified according to our changing technology and needs. The sources of sulfur and where it frequently occurs is explained. This discussion is followed by citing reviews of the four most important cycles, that is, the global sulfur cycle, hydrosphere, atmospheric sulfur budget, and the anthropogenic sulfur cycle. Sulfur production methods, coal combustion chemistry, and flue gas desulfurization are then described. The many uses of sulfur are described, including in medicine, agriculture, chemical industry, and the plastic industry. However, throughout the production of sulfur, problems affecting the environment occur, so environmental control and legislation are also discussed. Finally, the trends of sulfur research, production, use and recovery, role of chemistry, and the future overall area where science, energy, chemistry, and the environment exist together are presented. Chemists and chemistry students, industrialists, and environmental planners will find this guide to sulfur helpful. Lecturers in chemistry and researchers in the many fields of application of sulfur will likewise benefit from it.

Environmental Technologies to Treat Sulfur Pollution


Book Description

This second edition is fully updated with new material to create a comprehensive and accessible reference book: New chapters on sulfur removal via bioelectrochemical systems, use of sulfate radicals in advanced oxidation processes and sulfur nanoparticle biosynthesis. New sections on: sulfur cycle chemistry and microbiology; sulfate removal vs. recovery of resources from sulfate-rich wastewaters; microaeration for biogas desulfurisation; biological treatment of gypsum and sulfur-rich solid waste; up-to-date process control for treatment of sulfur-rich waste streams. New case studies with emphasis on practices for sewer and steel corrosion control, odour mitigation, autotrophic denitrification and bioremediation of acid mine polluted sites in both developed and developing countries have been included. Novel concepts of environmental technologies to treat sulfur pollution of wastewater, off-gases, solid waste, soils and sediments are presented. Up-to-date research findings and innovative technologies for recovering resources, i.e. metals, fertiliser, biofuels and irrigation water, from sulfur polluted waste are provided. This book may serve both as an advanced textbook for undergraduate and graduate students majoring in environmental sciences, technology or engineering as well as a handbook for tertiary educators, researchers, professionals and policymakers who conduct research and practices in the sulfur related fields. It is essential reading for consulting companies when dealing with sulfur related environmental (bio)technologies.




Bioelectrochemical Systems


Book Description

In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.

Biogenic Sulfur in the Environment


Book Description

Features state-of-the-art research on the fate and origin of natural (as opposed to pollutant) sulfur compounds, specifically, the cycling of biologically produced sulfur throughout the environment. Covers terrestrial and freshwater systems: emissions and transformations, oceans: distributions, biological transformations, and chemical transformations, and atmosphere: distribution, gas-phase transformations, and aqueous-phase transformations. Analytical techniques and up-to-date bibliographies are included as well as new research results never before published.
