The fluid flow in a distillation column was studied by measurements of the discrete residence time distribution. The column, 100 mm in diameter was fitted with 5 sieve plates of 14.8% free area with a 6.1 mm hole diameter on a 635 mm plate spacing. The periodic control was obtained using a JOLT microprocessor system. An analysis of the discrete residence time distribution yielded the parameters in the (2S) model that describes the fluid flow. Modifications to the column internals are required to alter these parameters, if the maximum separation improvements are to be obtained.
