LPG level control

The interface gauge should be located at the top, while the level gauge at the bottom should be used to monitor low liquid levels during shutdown or startup
This should be related to the type of tray or packing; if the liquefied gas in the tower is the dispersed phase, then the top level of the tower needs to be controlled； When the desulfurizer in the tower is the dispersed phase, it controls the bottom level of the tower. However, for safety reasons, even if the upper limit is controlled at the top of the tower, a limit indicator must also be installed at the bottom of the tower to enable timely detection of any abnormal operating conditions (such as tray blockage), thereby preventing accidents caused by liquefied gas being carried out along with the desulfurizing agent from the bottom of the tower.
