Physico-Chemical Properties of Supercritical Fluids

A supercritical fluid (SCF), which is kept beyond its critical point in both temperature and pressure, is defined as a high-density and noncondensable fluid. Figure 1shows the phase diagram of a pure substance. At the triple point, the three phases (gas, liquid, and solid) of the substance coexist in thermodynamic equilibrium. As the temperature goes high, the substance coexists in two phases (i.e., gas and liquid). At the critical point and in the region the temperature and the pressure are above the critical temperature and pressure, the substance exists in a single gaseous phase. The substance in this region is defined as in the SCF state. Thermophysical properties of a SCF are as follows: (i) intermediate density between a gas and a liquid, (ii) intermediate diffusion...
