Is it necessary to relieve pressure when the liquid from the pressurized reboiler in double-effect distillation enters the atmospheric-pressure column?

It’s not necessary. Liquid pressure has no effect; it is still pumped into the tower as usual.
Since the pressure tower is at 4 bars and the atmospheric pressure tower is at 1 bar, wouldn’t sending the material directly to the atmospheric pressure tower cause damage to the equipment or something similar?
No, you always have a flow control valve for the liquid feed, right? The pressure on the secondary side of the control valve can be set to 1.5 bar; simply reduce the pressure and feed it to the second tower.
There’s no air leakage; how could there be pressure leakage?
