Column Internals Liquid Distributor
Liquid distributors are used in packed towers above each bed of packing. The liquid distributor is located above the bed, usually 6 to 8 in (150-200mm) above the packing.
Column Internals Bed Limiter
For metal and plastic random packings, bed limiters are recommended when there is the potential for sufficient vapor load to fluidize the top of the bed. Generally, this occurs during upset conditions, which are difficult to predict.
Column Internals Support Grid
Design of the support grid allows free and uniform passage of gas and liquid so that capacity of the packing is not limited.
Column Internals Support Plate
Support plates for random and structured tower packings. Regardless of the packing, each plate incorporates several critical design factors.
Column Internals Feed Device
Obtaining desirable tower performance requires the proper handling of liquid and vapor entering the column. The types of feeds, or inlets, into a column can generally be classified into four major categories
Column Internals Liquid/Liquid Extraction
Packing is used in counter-current liquid/liquid contactors with special internals to disperse one of the phase. Selection and arrangement of the internals depends on which phase (light or heavy) is continuous and which is dispersed.
Column Internals Liquid Collector
Liquid collection from between packed beds is frequently required. Liquid collectors are used in three main cirnumstances
