Pollution Prevention for Chemical ProcessesThis timely text offers coverage of pollution prevention fundamentals, featuring examples and case studies drawn from the chemical process industries. Topics are presented on three different levels-macro, meso, and micro. The book's multifaceted approach provides a complete picture of current waste minimization theory and practice.Macroscale Comprehensive analysis of the flow of materials in the United States, from natural resource extraction to consumer product disposalOverview of waste generation and management for different pollutant typesAssessment of pollution prevention opportunities using industrial ecology and product life cycle frameworksMesoscale Detailed coverage of pollution prevention in chemical manufacturing processesWaste audits, emission inventories, flow sheet analysis, and many other important toolsWaste reduction for unit operations, techniques for measuring economic benefits of pollution prevention, and moreMicroscale Case studies of reaction pathway analysis and material design methodsComplete with case studies that give the material a real-world edge, plus worked examples to reinforce learning, this text is valuable to both advanced students and practitioners of chemical and civil engineering.

Field-tested methods for measuring and mitigating oil and gas methane emissions Oil and gas supply chains globally emit about 100 million tons of methane per year, yet accurate measurement and mitigation remain significant technical challenges. Methane Emissions in Oil and Natural Gas Supply Chains: A Practical Guide draws on over a decade of research to translate emissions data into actionable emission reporting and climate accountability frameworks for the energy sector. The book provides field-tested tools for quantifying methane across production, processing, and transmission segments. It covers detection technologies, emissions modeling methodologies, and geospatial lifecycle assessment approaches. Problem sets for training make the content directly adaptable for workforce development programs and university classrooms alike. Readers will also find: Practical methods for estimating and reporting methane emissions aligned with evolving regulatory and corporate reporting requirementsStrategies for translating complex atmospheric chemistry data into operational decisions supporting both compliance and environmental stewardship goalsGuidance tailored for international capacity-building programs addressing methane emission reporting across diverse regulatory and operational contexts worldwideAdaptable training content designed for engineers, policymakers, and researchers entering the methane emissions measurement and mitigation fieldDesigned for oil and gas technical professionals, management teams, and regulatory personnel overseeing methane-related policies, this book also serves emerging researchers in climate science, environmental engineering, and energy systems. It provides evidence-based methods needed to advance methane emission reporting across operational and policy domains.

The National Center for Intermedia Transport Research (NCITR) was established at UCLA in 1982 by EPA as one of six Centers of Excellence for the study of environmental pollution problems. One of the functions undertaken by the NCITR has been to hold periodic workshops and to provide a forum for the discussion of current topiCS in the environmental pollution arena. To this end, two other workshops have previously been held. The first, held in November 1982, was chaired by H. R. Pruppacher, R. G. Semonin and W. G. N. Slinn on Precipitation Scavenging, Dry DepOSition and Resuspension. The second, held in January 1986, was chaired by Y. Cohen on Pollution Transport and Accumulation in a Multimedia Environment. The present workshop, chaired by D. T. Allen, Y. Cohen and I. R. Kaplan, was held on August 24-26, 1988 in Santa Monica, California. The title of the workshop was Intermedia Pollutant Transport: Modeling and Field Measurements. Approximately one hundred individuals participated and twenty five papers were given, mostly by invitation. The workshop was divided into the following four broad topiCS: 1) Transport of Pollutants from the Atmosphere, 2) Transport of Pollutants from Soils and Groundwaters, 3) Transport of Pollutants from Lakes and Oceans, and 4) Multimedia Transport of Pollutants. The last afternoon was reserved for a Panel Discussion.
