Effect of tower pressure changes on components.
Thread Content
If the tower pressure changes increase or decrease, in order to keep the sensitivity plate unchanged while all other conditions remain the same, should the reboiler operation be increased or decreased?
As the tower pressure increases, reduce the reboiler temperature (reduce the heating rate). As the tower pressure drops, increase the reboiler temperature (increase the heating rate). But it takes a process, and it doesn’t show results immediately.
If the heat exchange efficiency of the top condenser is poor, then what was mentioned above probably won’t work
Since the tower pressure has changed, the sensitivity plate should change as well. You deliberately prevent it from changing, but the components on the sensitivity plate have actually changed.
If the tower pressure rises abnormally, the reboiling needs to be reduced. If the tower pressure increases due to an increased load, the temperature of the sensitive plate needs to be increased accordingly
