Introduction
The worldwide focus on technology development must include new industrial processing method that support pollution prevention (change in production methodlogy ).
SC fluids as an alternative to traditional solvents. it would be an extremely attractive proposition to have media that would serve as a versatile solvent,without carcinogenic properties.
What is supercritical fluid?
•Intermediate between liquid and gases.
•Supercritical fluids are highly compressed gases which combine properties of gases and liquids in an intriguing manner
•Fill any size of container,like a gas and dissolve material like a liquid.
•A supercritical fluid has densities similar to that of liquids, while the viscosities and diffusivities are closer to that of gases.
•The density of a supercritical fluid is extremely sensitive to minor changes in temperature and pressure near the critical point.
