Seeking help regarding the inability to increase the temperature in the distillation tower! ! !
Thread Content
I have a tower whose function is to separate ammonia from the materials. Recently, it has been impossible to increase the temperature of this tower; the temperature in the middle part of the tower is extremely low. The product at the bottom of the tower does not meet the standards as it contains too much ammonia. If a little steam is added, the temperature of the tower rises, and the reflux rate also decreases significantly. Why is that? ? Seeking advice
Is the tower liquid level too high, causing the tower to be flooded? Lower the liquid level a bit.
The wastewater processed by the ammonia vaporization tower is usually salty; could it be that the internal components are clogged? Check the overall tower pressure drop and analyze it.
The tower is flooded, or there may be a partial blockage; it’s also possible that the feed temperature or composition has changed significantly. Let’s conduct a thorough analysis
