Abstract
The phenomenon of liquid flooding, as a special flow state in gas-liquid countercurrent processes, can cause adverse effects such as reduced production efficiency and increased energy consumption, seriously restricting the operation and design of gas-liquid mass transfer equipment. Real time monitoring of the operation status of the packed tower not only ensures its normal operating conditions, but also helps to improve equipment efficiency, which has important practical significance and industrial application prospects. This article first reviews the current research status of liquid flooding monitoring, and proposes to use the key variable of tower pressure difference as an important variable for liquid flooding monitoring to monitor and regulate the pressure difference inside the tower. The effectiveness and superiority of monitoring have been verified through experiments, which can achieve indirect monitoring of liquid flooding.
