SCF (Supercritical Fluid) Technology

Supercritical Fluid (SCF) technology involves using a fluid at a temperature and pressure above its critical point, where it exhibits properties of both liquids and gases. This state allows the fluid to effectively penetrate materials like a gas but dissolve substances like a liquid. Commonly, carbon dioxide is used as the supercritical fluid because it is safe and inexpensive. SCF technology is often employed in processes like extracting sensitive compounds (e.g., caffeine from coffee) without using harmful solvents, making it an efficient and environmentally friendly method for purification, extraction, and material processing.
