High pressure extraction with near and supercritical fluids has been in use on an industrial scale for decades. It is a well-established process and is, e. g., used for decaffeination of coffee with carbon dioxide. Apart from that well-known process, there are several others which make use of the unique and special properties of near and supercritical fluids. These properties and some of these processes are described in this article, i.e., dry ice-blasting, high pressure flash-cleaning, cleaning of textiles and parts, a gas supported pressing process (gas assisted pressing (GAP)/gas assisted mechanical expression (GAME) process), splitting of emulsions, high pressure decontamination and absorption with ionic liquids.
