    Subcritical water is a green extraction solvent compared to conventional extraction solvents. While experimental results on subcritical water extraction (SWE) technology have been published piecemeal, there has been no comprehensive review of the state of the art. Green Extraction in Separation Technology fills that gap, serving to cover extracting with subcritical water as an environmentally friendly solvent.


    • Presents new technologies for extracting natural compounds from plants and compares the advantages and disadvantages versus SWE
    • Explains research on SWE over the last 15 years
    • Offers an overview of the solubility of different compounds in SWE and related theoretical content
    • Discusses modeling of SWE and describes the development of a new model for this process

    This monograph is aimed at researchers and advanced students in chemical and biochemical engineering.

    1. New Technologies for Extracting Natural Compounds from Plants

    2. Review of Subcritical Water Extraction (SWE)

    3. Solubility of Subcritical Water
