WebApr 11, 2024 · Foam interferes with mass transfer and thus reduces separation performance. In absolute terms, foam-loaded structured packings showed the highest separation performance as compared to random packings. In the presence of foam, the pressure drops were significantly higher than the pressure drops without foam. Continuous foam separation is a chemical process closely related to foam fractionation in which foam is used to separate components of a solution when they differ in surface activity. In any solution, surface active components tend to adsorb to gas-liquid interfaces while surface inactive components … See more Processes similar to continuous foam separation have been commonly used for decades.
