Fluiddynamik von Kolonneneinbauten unter Berücksichtigung von Fouling Hydraulics of Column Internals under Consideration of Fouling

Abstract

The hydraulic calculation of column internals is crucial for their design. The various fouling effects (due to crystallization, particles, chemical reaction) influence the hydraulics of columns in different ways (capacity, separation efficiency). However, current hydraulic models are based on clean systems and do not consider fouling. By properly taking into account the geometrical parameters affected by fouling, the classical models can be used to calculate the state of internals as they evolve over time.
