Depressurization tower, with positive pressure at the bottom of the tower
Thread Content
What causes the pressure at the bottom of the vacuum tower to become positive? Seeking advice from experts
What are the specific parameters of the vacuum distillation tower? This shouldn’t be here! Could you describe the specifics of the vacuum distillation tower, or upload a picture so that an analysis can be done based on the actual conditions?
Excessive gasification volume results in the tower top failing to cool down; the gas-phase pipelines get blocked, the vacuum pump operates in reverse, the pressure gauge connection tubes become clogged, and instrument failures occur
Solved: The pressure-relief blowing function has been turned off, and it is gradually shifting to negative pressure
The negative pressure at the top of the tower is very low, and the temperature at the top is very high. Are you using steam extraction or mechanical compression – multiple stages? Check your instruments
