supercritical fluid — Svenska översättning - TechDico

The incentive for work on water has been its use in supercritical pressure "boilers" for power stations, particularly in the U.S.A. and the U.S.S.R. liquid CO2 is heated in a pressure cell until it reaches the critical point were it changes into a supercritical fluid Supercritical Fluid: Fluid over its critical temperature and pressure, exhibiting good solvent power ; in most applications, carbon dioxide is used pure or added with a co-solvent ; the main interest of supercritical fluids is related to their tunable ” properties, that can be“ In general, supercritical fluids exhibit properties that are intermediate between those of liquids and gases, and these properties are greatly influenced by temperature and pressure. As a result, supercritical fluids are used in a variety of applications such as mobile phases in chromatography, extraction agents, and chemical reaction solvents.

Tunable solvent properties and environmental compatibility make supercritical fluids desirable agents in the chemical process industry. Supercritical Fluid: Fluid over its critical temperature and pressure, exhibiting good solvent power ; in most applications, carbon dioxide is used pure or added with a co-solvent ; the main interest of supercritical fluids is related to their tunable ” properties, that can be“ Supercritical fluid extraction using carbon dioxide (CO (2)) has been recognized as a green technology. It is a clean and versatile solvent with gas-like diffusivity and liquid-like density in the supercritical phase, which has provided an excellent alternative to the use of chemical solvents. When a gas such a carbon dioxide is compressed and heated, its physical properties change and it is referred to as a supercritical fluid. Under these conditions, it has the solvating power of a liquid and the diffusivity of a gas.
