on phase behavior in supercritical fluid systems and may generate different types of phase equilibria in the system. Hence, it is of great importance to have a proper knowledge of the high-pressure phase behavior of fluid mixtures in a phase diagram framework. Although it is very important to study the phase

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, but below the pressure required to compress it into a solid.It can effuse through porous solids like a gas, overcoming the mass transfer limitations that slow liquid transport through such materials. SCF are much superior to gases in their

Instead the water is in a supercritical fluid state. Carbon dioxide can also be put into a supercritical fluid state as well, and which may also someday prove useful to the energy industry. Any fluid pushed to a temperature and pressure where it is no longer possible to differentiate between the liquid and gas phase becomes a supercritical fluid. Fig 1: Supercritical fluid dyeing graph (Source – Wikipedia) A supercritical fluid may be characterized best by referring to a phase diagram as shown for in Fig 2. A liquid can be converted to a supercritical fluid by increasing its temperature (and consequently its … However if we move from the liquid to the supercritical fluid by increasing the temperature, as shown by the arrow in this diagram: then we measure neither a first or second phase transition.

• Viscosity is lower so very useful for compound which have no functional group, as detection method in HPLC fails. 10. Phase Diagram of CO2 6. [Department of Pharmacy (Pharmaceutics)] | Sagar Savale 6December 23, 2015 11. Carbon dioxide density-pressure phase diagram 12.

Phase diagram of a ternary system Generalized phase diagram of a ter- at constant pressure and temperature nary system at constant pressure 8. A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points).

Figures 1 and 2 show two-dimensional projections of a phase diagram. In the pressure-temperature phase diagram (Fig. 1) the

Phase diagram. The dotted region above the critical point is the supercritical fluid (source: Wikipedia).

1) the boiling curve separates the gas and liquid region and ends in the critical point, where the liquid and gas phases disappear to become a single supercritical phase. The appearance of a single phase can also be observed in the density-pressure phase diagram for carbon dioxide (Fig. 2). The system consists of 2 phases in equilibrium, a dense liquid and a low density gas. Phase Diagram for Carbon Dioxide This diagram indicates the supercritical fluid region of CO 2.
