Degassing, also known as degasification, is the removal of dissolved gases from liquids, especially water or aqueous solutions. There are numerous methods for removing gases from liquids. Gases are removed for various reasons. Chemists remove gases from solvents when the compounds they are … See more The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. See more Ultrasonic liquid processors are a commonly used method for removing dissolved gasses and/or entrained gas bubbles from … See more Bubbling a solution with a high-purity (typically inert) gas can pull out undesired (typically reactive) dissolved gases such as See more In this laboratory-scale technique, the fluid to be degassed is placed in a Schlenk flask and flash-frozen, usually with liquid nitrogen. Next a vacuum is applied, perhaps to attain a vacuum of 1 mm Hg (for illustrative purposes). The flask is sealed from the … See more Generally speaking, an aqueous solvent dissolves less gas at higher temperature, and vice versa for organic solvents (provided the solute and solvent do not react). … See more Gas-liquid separation membranes allow gas but not liquid to pass through. Flowing a solution inside a gas-liquid separation membrane and evacuating outside makes the dissolved gas … See more If oxygen should be removed, the addition of reductants is sometimes effective.
