Column Components

Column components provide the optimum solution for every requirement such as distillation, absorption, reaction, rectification & extraction because of wide range of different components available. This applies not only to various types of column & pipe sections available but also to the wide selection of internals & packing that can be supplied.

Column Sections

Depending on the nominal size, column sections are supplied in 1000 and/or 1500 mm lengths. The column sections are provided with fused shelf where packing support can rest. Column section can also be provided with a thermometer branch below the packing support.

Column section & pipe section may be used for construction of the columns of all nominal bores provided the weight of the packing & retained liquid does not exceed the load bearing capacity of the support.

Column Section for Liquid Distribution

Irrespective of the nominal size, these column sections are supplied in one length only so that they still provide sufficient height for packing.

They have three extra side branches offset at 120° from each other so that a nozzle type distributor can be fitted to redistribute the liquid. This column section can be supplied with or without thermometer branch.

Packing Supports

For nominal size up to DN 300 we supply “CP” borosilicate glass 3.3 packing support for the column sections. For larger diameters we provided “HD” packing support for which a combination of glass & PTFE is used.

Both types are seated on PTFE ring which is supplied complete with the support. Details concerning free cross sections of the support and their load bearing capacities when loaded evenly and on minimum size of the packing to be used are given on the previous page.

Column Packing

Due to their low bulk densities, glass raschig rings are particularly suitable for packing glass columns. The ratio of column diameter to packing diameter should not be less then 8:1.

The technical detail of the raching rings are listed below.

Notes of use of column packing

Generally, the ratio of Column diameter to packing diameter should not be less than 8:1.

When using smaller packing size, a small layer of larger packing should be used on Packing support, to prevent the smaller packing falling through.

Due to their low bulk densities, Glass Rasching rings are particularly suitable for packing glass columns.

In vacuum application and applications involving high vapour velocities, packing may be, lifted and may damage to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used.



Packing Retainers / PTFE Perforated Plates

Packing retainers are installed above packed column section to prevent any carry over of column packing resulting in damage to reflux separators or condenser. They are installed in the same way as gasket between two flat buttress end and thus no additional gasket is required.

PTFE Redistributors

Redistributors are made of selected PTFE. They are clamped in the coupling of a pipe or a column section in the same way as a gasket so the no additional gasket is required.

They act as simple liquid collectors and direct the liquid away form the walls. Their inside diameter is designed to match nozzle type distributors.

Reflux Separators

Reflux separators are used to control the reflux ratio in rectification columns to separate the condensate produced in to reflux & take off streams. They can be of manual or magnetic types.

Manually Operated Reflux Dividers

In these units, the reflux adjusted by means of a manually operated valve on the distillate outlet connection. When the valve is fully open, the divider is set to total distillate off-take as the return pipe is located higher then the outlet connection. By regulating the valve, the reflux ratio can be continuously adjusted up to total reflux.

Electro-Magnetically Operated Reflux Separators

This type of reflux separator uses a swinging funnel mechanism. The funnel which has a soft iron core sealed in to it, is operated magnetically from outside the column by means of a timer.

When the electro magnet is not energized the funnel is at rest & all the condensate is returned to the column. Activation of the electromagnet moves the funnel in to the off-take position and the distillate is removed from the column via the off-take branch.
