Density of supercritical co2
electricity to the grid. In this article, a PTES variant that uses supercritical carbon dioxide (sCO 2) as the working fluid is introduced. sCO 2-PTES cy cles have higher work ratios and power densities than the systems based on ideal gases that have been investigated to date. Furthermore, sCO 2... supercritical fluid'. Supercritical CO2 has the properties both the liquid (high solubility) and the gas (high diffusivity). Because supercritical carbon ...The supercritical carbon dioxide (SCO 2) is a physical state that the physical properties exceeding the critical point (7.38 MPa, 304.13 K). It is of low compression factor (low compression work) and high density (small turbomachinery size) near the critical point, and the critical temperature is near the room temperature [1] , [2] .
