Separation processes employing extraction in biotechnology. This publication describes separation processes involving extraction used in biotechnology, such as are being studied at the Institute for Thermal Process Engineering and Environmental Engineering at the Technical University of Graz, Austria. It is shown that research in this area is also on the increase due to the rapidly growing need for processes. Reactive extraction and liquid membrane permeation are powerful tools for the separation, concentration, and purification of polar organic compounds such as carboxylic and hydroxycarboxylic acids. High pressure extraction has the advantage that no contamination of the desired materials takes place with carbon dioxide; however, this is offset by the high price of the process. In certain cases, when only low partitioning can be achieved by conventional extraction whereas enrichment is a predominant criterion, salting out could provide an answer.
