True or False: In a plate tower, a certain number of plates are installed inside the tower; gas passes through the liquid layer on these plates in a bubbling or spraying manner, allowing close contact between the two phases for mass transfer to occur. The component concentrations in the two phases vary continuously along the height of the tower. ( ) Answer: Incorrect. In a plate tower, a certain number of plates are installed inside the tower; the gas passes through the liquid layer on these plates either by bubbling or spraying, thereby allowing close contact between the two phases and facilitating mass transfer. The component concentrations in the two phases change stepwise along the height of the tower. Your participation is the greatest support for our work.
