Fundamentals and Applications of Supercritical Carbon Dioxide (SCO2) Based Power Cycles aims to provide engineers and researchers with an authoritative overview of research and technology in this area. Part One introduces the technology and reviews the properties of SCO2 relevant to power cycles. Other sections of the book address components for SCO2 power cycles, such as turbomachinery expanders, compressors, recuperators, and design challenges, such as the need for high-temperature materials. Chapters on key applications, including waste heat, nuclear power, fossil energy, geothermal and concentrated solar power are also included. The final section addresses major international research programs. Readers will learn about the attractive features of SC02 power cycles, which include a lower capital cost potential than the traditional cycle, and the compounding performance benefits from a more efficient thermodynamic cycle on balance of plant requirements, fuel use, and emissions. Represents the first book to focus exclusively on SC02 power cycles Contains detailed coverage of cycle fundamentals, key components, and design challenges Addresses the wide range of applications of SC02 power cycles, from more efficient electricity generation, to ship propulsion

Supercritical fluid extraction is an environmentally safe and cost-effective alternative to traditional organic solvents. Carbon dioxide is widely used as the solvent of choice for applications such as caffeine and nicotine extraction due to its mild critical temperature, nontoxicity, nonflammability, and low cost. Introducing the most complete collection of supercritical CO2 solubility data currently available, Solubility in Supercritical Carbon Dioxide features experimental data on more than 780 solutes in consistent units and an easily accessible format. This book reflects the authors’ painstaking efforts to compile solubility data for an extensive variety of compounds including liquids, solids, polymers, foods, drugs, nutraceuticals, pesticides, dyes, and metal complexes. Each of the more than 1200 tables is arranged in alphabetical order by compound, includes a graphical plot of its data, and features the following information: Compound name, molecular formula, and molecular weight Temperature and pressure given in Kelvin and bar, respectively Name and amount of cosolvent, if applicable Molar or mass solubility, when applicable Mole- or mass-fraction solubility Synonyms for the compound, where available Reference source for the data Density data for CO2 appears in one appendix, while a complete list of solutes by molecular formula appears in the other. Clear, consistent, and carefully organized, Solubility in Supercritical Carbon Dioxide is the most convenient quick-lookup guide for reliable data.

Recently, supercritical fluids have emerged as more sustainable alternatives for the organic solvents often used in polymer processes. This is the first book emphasizing the potential of supercritical carbon dioxide for polymer processes from an engineering point of view. It develops a state-of-the-art overview on polymer fundamentals, polymerization reactions and polymer processing in supercritical carbon dioxide. The book covers topics in a multidisciplinary approach starting from polymer chemistry and thermodynamics, going through monitoring, polymerization processes and ending with polymer shaping and post-processing. The authors are internationally recognized experts from different fields in polymer reaction engineering in supercritical fluids. The book was initiated by the Working Party on Polymer Reaction Engineering of the European Federation of Chemical Engineering and further renowned international experts.

"Supercritical Carbon Dioxide: Functions and Applications presents a constructive overview on the use of supercritical carbon dioxide as an alternative solvent to obtain natural products, instead of using conventional organic solvents. The overview includes the fundamentals, industrial applications, and main experimental findings based on recent studies about supercritical extraction using carbon dioxide. Next, the impregnation of polymer materials with two different ketones with known activity against the main pests of stored products (thymoquinone and R-( )-pulegone) is presented, and the effect of the process variables on ketone loading and the final activity of the impregnated materials is discussed. The authors go on to evaluate the effect of temperature (T: 41-69ÀC) and CO2 density (D: 843-957 kg/m3) on the extraction yield of oil and bioactive compounds of N. gaditana using supercritical CO2, a technology that allows for the selective extraction of compounds of interest by varying the pressure and temperature conditions, producing natural extracts without the use of liquid organic solvents. Hydrophobic modifying coatings on textile materials made of polyethylene terephthalate were obtained by precipitating a low molecular weight fraction of ultrafine polytetrafluoroethylene. The modifier application conditions are also defined. The closing chapter provides an overview on the principal applications related to the supercritical fluid extraction of active compounds from tobacco and tobacco waste, emphasizing the influence of the most important processing parameters on the extraction yield"--
