Supercritical drying bypasses the liquid-gas boundary, avoiding damage to delicate structures caused by capillary stress. Supercritical fluids are used and there are various methods, including a safer low-temperature method using carbon dioxide. When a substance is dried via the normal methods of applying heat and pressure at a finite rate, the substance passes through the […]
A supercritical fluid is a substance heated above its critical point, with properties of both a liquid and a gas. Carbon dioxide is often used as a supercritical fluid due to its critical temperature and pressure. It can be used in various industries, including food and pharmaceuticals, to extract compounds without leaving chemical residue. A […]
Supercritical extraction uses supercritical fluids, such as carbon dioxide, to act as a solvent and separate constituents of a mixture. It is environmentally friendly, fast, and allows for control over the final product. It is useful for industrial manufacturing and laboratory settings. However, it can be expensive to run due to the need for high […]
Supercritical gas is a state of matter with properties of both a liquid and a gas, only created above a material’s critical point. It has industrial applications, including extracting caffeine from coffee beans and oxidizing hazardous waste. Supercritical gas, more correctly known as supercritical fluid, is a distinct state of matter that has properties of […]
