/ Supercritical Drying

SUPERCRITICAL DRYING (CPD)

Supercritical fluids are obtained by heating a gas above its critical temperature or by increasing the pressure above its critical level. Supercritical drying consists of adjusting the temperature and pressure to transform the solvent into a supercritical fluid and then in gas. The liquid present in the system is therefore completely removed. This method is often used in Micro-electro-mechanical systems (MEMS) because it prevents damage to the fine machinery of these devices during the transition of the solvent between liquid and gas.

Uses

-Remove the liquid phase from a system
