Definition of extraction - Chemistry Dictionary

Easy Example of Extraction Tea-making is a very basic non-laboratory extraction. You boil tea leaves in water to extract the tannins, theobromine, polyphenols, and caffeine out of the solid tea leaves and into the liquid water. You are then free to drink and enjoy the water and the extracted substances it contains. Laboratory Extractions

Chlorine production - Wikipedia

Gas extraction. Chlorine can be manufactured by the electrolysis of a sodium chloride solution (), which is known as the Chloralkali process.The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2).These two products, as well as chlorine itself, are highly reactive.

Supercritical Fluid Extraction - an overview

Supercritical-fluid extraction has the advantage that slight changes in temperature and pressure within the critical region give extremely large changes in solvent density and solubility. There is greater flexibility in the process operating parameters of pressure and temperature as compared with conventional liquid-liquid extraction processes.

PDF Practica in Process Engineering II Extraction

Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed (Phase 1), by means of a liquid immiscible solvent (Phase 2). The transfer of the components from the feed to the solvent is controlled by the solubility behavior of each component in the corresponding phase.
