The bubble column is good; switching to a plate column reduces efficiency?
In fact, the bubble column also belongs to the category of plate columns; perhaps what you mean is the tray column. Tray columns have a high porosity, which allows for better processing efficiency – they are generally 10%–15% more efficient than bubble columns. Moreover, their structure is simple, making maintenance easier, and their cost is 40% lower. The main drawback is that they cannot handle dirty, viscous materials or those containing solid particles
