Principles of Super Critical Liquid Extraction?
Supercritical fluid extraction is a process that uses supercritical fluids, such as carbon dioxide, to extract solutes from solid or liquid samples. The main principles include the use of a supercritical fluid as the solvent, which offers benefits such as tunable solvating power, high efficiency, and minimal residue in the extracted material. The process involves applying high pressure and temperature to the supercritical fluid to reach a state where it exhibits properties of both liquids and gases, making it highly effective for extraction purposes.
Why is nitrogen not used in supercritical fluid extraction?
Because at room temperature it behaves like gas. Although it is in supercritical state, its density becomes very low on temperatures far above critical value, so it behaves like gas and it's not useful for extraction.

What did jennie r Patrick invent?
Jennie R. Patrick is not credited with any inventions. She is known for her work on supercritical fluid extraction and for being part of the Alabama school integrations.
Is liquid nitrogen a supercritical fluid?
No, liquid nitrogen is not a supercritical fluid. A supercritical fluid exists at a temperature and pressure above its critical point where it displays properties of both a liquid and a gas. Liquid nitrogen remains in the liquid state at low temperatures and normal pressures.
What is the supercritical state?
(I suppose that you mean supercritical state of fluid.)Supercritical state of liquid-gas is a state that liquid state and gas state stop to exist at particular temperature and pressure.There is only just fluid state which has both liquid and gas property and if you change the pressure or temperature just a bit, it will change to one of the state.How to achieve supercritical state ?The supercritical state is done at HIGH TEMPERATURE and PRESSURE.For example, the famous CO2 fluid (used to separate caffeine from the coffee bean) is acquired at 304.1 Kelvin and 72.8 atm.
How is the soloubility of gases in liquied used in industry?
The solubility of gases in liquids is used in various industries for processes like carbonation in the beverage industry, oxygenation in water treatment plants, and in extraction techniques such as supercritical fluid extraction. This property allows for the efficient transfer of gases into liquids for specific applications.
