Distillation Columns – Internal Reflux Control

To achieve satisfactory composition control, the most common approach is to employ an advanced regulatory control (ARC) technique referred to as internal reflux control. The internal reflux, that is, the actual flow of liquid from tray 1 to tray 2, can be calculated as follows: IR = R * (1+ Cp * ( TO – TR) / Λ) Where: R = External reflux flow.
