Experimental characterization and computational fluid dynamics simulation of gas distribution performance of liquid (re)distributors and collectors in packed columns
The usability of a state of the art computational fluid dynamics simulation package as a tool for analyzing the fluid-dynamic performance of internals encountered in packed distillation columns, such as initial gas distributors, liquid distributors and liquid collectors is demonstrated. A 1.4 m internal diameter column hydraulics simulator was used to provide detailed experimental evidence on the gas distribution pattern imposed by various types of column internals. The comparison of measured and predicted profiles for single-phase gas flow conditions indicates a strikingly good agreement.
