  2. Supercritical carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Supercritical_carbon_dioxide

    Supercritical carbon dioxide (s CO 2 ) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure . Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when cooled and/or pressurised sufficiently.

    Initially, a small amount of carbon dioxide was soldered in a small glass ampoule at a pressure of about 70 atmospheres. When the ampoule was heated, the carbon dioxide inside began to pass into a supercritical state, thereby creating an unusual state of matter, not liquid and not gas.

    ‡ Second column of table indicates solubility at each given temperature in volume of CO 2 as it would be measured at 101.3 kPa and 0 °C per volume of water. The solubility is given for "pure water", i.e., water which contain only CO 2. This water is going to be acidic. For example, at 25 °C the pH of 3.9 is expected (see carbonic acid).

  5. Supercritical carbon dioxide blend - Wikipedia

    en.wikipedia.org/wiki/Supercritical_carbon...

    Efficient supercritical CO 2 power cycles requires that the compressor inlet temperature is close to, or even lower than, the critical temperature of the fluid (31 °C for pure carbon dioxide). When this target is reached, and the heat source is higher than 600–650 °C, then the sCO 2 cycle outperforms any Rankine cycle running on water ...

    en.wikipedia.org/wiki/Supercritical_fluid

    Supercritical water oxidation uses supercritical water as a medium in which to oxidize hazardous waste, eliminating production of toxic combustion products that burning can produce. The waste product to be oxidised is dissolved in the supercritical water along with molecular oxygen (or an oxidising agent that gives up oxygen upon decomposition ...

    A Knoxville company called Holocene caught the attention of foundations backed by Elon Musk and Bill Gates by sucking CO2 straight from the air. A Knoxville machine is turning pollution on its ...

    Eberflus acknowledged that the Bears did a poor job of blocking, but believes that the Packers made illegal contact with long snapper Scott Daly on the play and wants the NFL to take a second look.

  9. CO2SYS - Wikipedia

    en.wikipedia.org/wiki/CO2SYS

    CO2SYS is a family of software programs that calculate chemical equilibria for aquatic inorganic carbon species and parameters. Their core function is to use any two of the four central inorganic carbon system parameters (pH, alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide) to calculate various chemical properties of the system.
