There is too much water in the fuel tank of the methanol synthesis gas compressor.

In the combined compression unit composed of Hangzhou Steam Turbines and Shenyang Blower, there is always water in the drain valve at the bottom of the oil tank! Please, esteemed experts, try to analyze the reasons!
It leaks in through the steam seal located near the bearing; the pressure of that steam seal can be adjusted.
Assuming that there are no leaks in the tank heater (steam) or the oil cooler, it is possible that steam from the turbine shaft seal has entered the bearing box, condensed there, and then made its way into the tank.
In most cases, this occurs when steam from the turbine’s shaft seal leaks into the lubrication chamber of the lubricating oil, and from there it enters the oil tank. It is usually the low-pressure side of the shaft seal that leaks. Our solution is to introduce nitrogen into the sealing chamber of the lubricating oil to create an air seal, which thereby **reduces the amount of steam that leaks in**. I hope this can be helpful to you.
We did the same here as well, by adding a nitrogen seal to the turbine.
