Problems with continuous reforming stabilizers
Thread Content
What are the effects of varying the reflux temperature of the stabilizer on the tower? A detailed explanation~ The heavy components at the bottom of the tower, the light components at the top, and their impact on mass and heat transfer within the tower~
I suggest that the original poster, just like me, keep a copy of \"Principles of Chemical Engineering\" at hand to review theoretical knowledge at any time and think about it in relation to practical problems.
My understanding is that the reflux function is to remove the excess heat from inside the tower! It provides liquid-phase reflux on each tray of the distillation column, from the top of the column to the feed inlet, thereby creating conditions for gas-liquid mass and heat transfer; it removes excess heat from within the column and maintains thermal equilibrium at all points within it.
During operation, I encountered a situation where the pressure at the top of the tower was insufficient; after reducing the reflux and reboiling, the temperature at the bottom of the tower increased instead, and the tower pressure also rose back up.
