Level of methanol separator
Thread Content
What are the effects of high and low liquid levels in the methanol separator?
An excessively high liquid level can easily lead to gas carrying liquid, affecting the operation of the circulation pump and the methanol synthesis reaction. The liquid level is too low, which is unsafe; high-pressure gas enters the flasher, creating potential hazards for the equipment.
If the level of liquid in the separator is too high, the liquid will be carried into the circulation section along with the gas; in severe cases, this can lead to liquid slugging, which damages the compressor. Moreover, an increased methanol content in the gas entering the tower deteriorates the reactions taking place within the synthesis tower and exacerbates the formation of side reactions； If the liquid level is too low, air ingress accidents are likely to occur; high-pressure air entering low-pressure equipment systems can lead to explosions.
I agree with the second floor’s view: an excessive liquid level can flow into the circulation pump, causing liquid slugging and damaging the equipment; it can also contaminate the lubricating oil and enter the synthesis tower, leading to side reactions that affect the catalyst’s activity. On the other hand, an insufficient liquid level impairs the separation process, and the combination of high pressure and low pressure can result in accidents
