Studying the gas content and pressure difference in sectioned continuous action bubble column

Sectioning of bubble columns by perforated trays is one of effective methods of improving their operation. In article results of tested determination the influence of gas and liquids speeds, and also geometrical characteris-tics of sectioned trays on their hydraulic resistance and general gas content in the device are presented. De-pendence of the overall gas content in sectioned gas-liquid column from the resulted speeds of gas and liquid is installed. Conditions of stopping of liquid back-mixing across perforated tray in case of gas-liquid co-current flow were found.
