  2. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    The water temperature drops below the critical point as it does work in a high pressure turbine and enters the generator's condenser, resulting in slightly less fuel use. The efficiency of power plants with supercritical steam generators is higher than with subcritical steam because thermodynamic efficiency is directly related to the magnitude ...

  3. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist.

  4. Supercritical liquid–gas boundaries - Wikipedia

    en.wikipedia.org/wiki/Supercritical_liquid–gas...

    These criteria result in different boundaries in the pT plane. These lines emanate either from the critical point, or from the liquid–vapor boundary (boiling curve) somewhat below the critical point. They do not correspond to first or second order phase transitions, but to weaker singularities.

  5. Supercritical water reactor - Wikipedia

    en.wikipedia.org/wiki/Supercritical_water_reactor

    The SCWR operates at supercritical pressure. The reactor outlet coolant is supercritical water.Light water is used as a neutron moderator and coolant. Above the critical point, steam and liquid become the same density and are indistinguishable, eliminating the need for pressurizers and steam generators (), or jet/recirculation pumps, steam separators and dryers ().

  6. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    At the critical point, (304.1 K and 7.38 MPa (73.8 bar)), there is no difference in density, and the 2 phases become one fluid phase. Thus, above the critical temperature a gas cannot be liquefied by pressure. At slightly above the critical temperature (310 K), in the vicinity of the critical pressure, the line is almost vertical.

  7. Supercritical drying - Wikipedia

    en.wikipedia.org/wiki/Supercritical_drying

    Supercritical drying, also known as critical point drying, is a process to remove liquid in a precise and controlled way. [1] It is useful in the production of microelectromechanical systems (MEMS), the drying of spices , the production of aerogel , the decaffeination of coffee and in the preparation of biological specimens.

  9. Critical line (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_line_(thermodynamics)

    In thermodynamics, a critical line is the higher-dimensional equivalent of a critical point. [1] It is the locus of contiguous critical points in a phase diagram . These lines cannot occur for a single substance due to the phase rule , but they can be observed in systems with more variables, such as mixtures.
