  • Significant opportunity exists for the application of supercritical fluid (SCF) technology to coal processing, both for pretreatment of high sulfur coals, as well as liquefaction and treatment of coal liquids. (unt.edu)
  • LWRs
  • The conditions inside an SCWR are harsher than those in LWRs, LMFBRs, and supercritical fossil fuel plants (with which much experience has been gained, though this does not include the combination of harsh environment and intense neutron radiation). (wikipedia.org)
  • Separation
  • Supercritical airfoils feature four main benefits: they have a higher drag divergence Mach number, they develop shock waves further aft than traditional airfoils, they greatly reduce shock-induced boundary layer separation, and their geometry allows for more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow for a lighter wing). (wikipedia.org)
  • Supercritical fluid extraction is a green separation technology, which has been developed for decades and widely applied in traditional Chinese medicines or natural active components. (hindawi.com)
  • turbine
  • turbine speed increases dramatically, requires advanced materials) Ultra-supercritical - 1,400 degrees Fahrenheit and pressure levels to more than 5,000 psi. (wikipedia.org)
  • critical
  • A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. (wikipedia.org)
  • According to the website Civil Engineering Terms, supercritical flow is defined as follows: The flow at which depth of the channel is less than critical depth, velocity of flow is greater than critical velocity and slope of the channel is also greater than the critical slope is known as supercritical flow. (wikipedia.org)
  • The CO2 subsequently becomes supercritical post the injector and in the column oven when the temperature and pressure it is subjected to are raised above the critical point of the liquid and the supercritical state is achieved. (wikipedia.org)
  • More specifically, it behaves as a supercritical fluid above its critical temperature (304.25 K, 31.10 °C, 87.98 °F) and critical pressure (72.9 atm, 7.39 MPa, 1,071 psi), expanding to fill its container like a gas but with a density like that of a liquid. (wikipedia.org)
  • molecular
  • Considerable progress has been made in both adsorption measurement techniques and molecular simulation of adsorption on computers, rendering new insights into the nature of supercritical adsorption. (wikipedia.org)
  • current
  • The use of a supercritical Rankine cycle with its typically higher temperatures improves efficiency (would be ~45 % versus ~33 % of current PWR/BWRs). (wikipedia.org)
