Finding the Capacity of a Distillation Column

Reactions and Separations

Learn to identify the flood point and system limit of your distillation column to understand its capacity and ensure efficient operation.

The capacity of a distillation column is the upper limit of operation, which depends on criteria such as acceptable operability, pressure drop, maximum useful efficiency, and flood point. Flood point is the initiation of flood. During flood, the column becomes hydraulically limited, which is primarily characterized by an increase in pressure drop and buildup of liquid at the top of a section of packing or trays. System limit is an additional metric that should be kept in an engineer’s toolbox to estimate the ultimate capacity of a process. Although a significant amount of literature exists on these topics, valuable insights can be gained through a conceptual understanding of the fundamentals and characteristics of flood phenomena...
