Abstract

Fluid solvents, especially in the critical and supercritical regions, are of increasing interest for many fields. They are used as reaction or processing media with continously variable density and dielectric permittivity, high solvent power, low viscosities, and high diffusion coefficients. Examples of application fields include geology and mineralogy (e.g., hydrothermal synthesis), industrial high-pressure processes (e.g., the polymer industry), the oil and natural gas industries (e.g., tertiary oil recovery), and modern separation techniques, such as supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC). Supercritical fluids are promising solvents for chemical reactions (such as waste destruction by supercritical water oxidation (SCWO)), for the deposition of small-sized solid particles (by rapid expansion of supercritical solutions (RESS), or from gas-saturated solutions (PGSS)), and for the dyeing of textile fibers, etc. These and many other applications are discussed in the present chapter and other contributions in this volume.
