Fluctuations in the vent gas flow rate of the MTO wastewater stripping tower
Thread Content
There are fluctuations in the flow rate of the gas at the top of the wastewater stripping tower; the flow meter indicates that the pressure difference is too low. However, the flow rate of methanol vaporized by the stripping gas vaporizer fluctuates around 10 tons. Has anyone encountered such a problem? The top of the tower has three flow paths: a heat bypass, a line from the safety valve to vaporizer E1103, and a line from the safety valve to E1207, which then leads to the top reflux tank
The heat source of the carburetor is unstable, resulting in large fluctuations in the liquid level within the carburetor; this leads to unstable heat transfer, and as a consequence, the amount of methanol that vaporizes varies significantly.
I need to study how to maintain a stable flow rate of the stripping gas
The feed temperature of the stripper, the feed rate, the bottom temperature of the tower, and the reflux rate – all of these will affect the methanol flow rate in the stripping gas heat exchanger! ! ! !
Try using only one of the E1103 units; set the other one to a lower degree of operation as a thermal bypass. Using both units at the same time may lead to air competition
Is there any fluctuation in the pressure of the wastewater stripping tower? When the load in E1103AB changes
I’m not sure about the fluctuations in your tower pressure; how long after the installation was put into operation did this problem start to occur? I have encountered fluctuations in gas flow caused by variations in tower pressure before. It is recommended to install an oil separator in the sedimentation tank; otherwise, your feed composition will change, leading to fluctuations in tower pressure and flow rate.
