摘要：A degassing cyclone is a separator that is widely used for the removal of bubbles and dissolved gas from liquids. Gas bubbles move toward the swirling center region in a degassing cyclone due to centrifugal force. The dissolved gas is desorbed due to a decrease in the saturated solubility resulting from the pressure gradient in the degassing cyclone. Additional carrier gas bubbles with lower partial pressure lead to mass transfer at the turbulent bubble interface. The final state of the dissolved gas and carrier gas bubble in degassing cyclones is an important issue that can be used to develop a theoretical foundation for green separation engineering. The feasible development of this technology and potential applica-tions are discussed in this work.
