INTRODUCTION

Column components are extensively used in the chemical, pharmaceutical and allied industries together with other applications such as food and drink production, dye works and electroplating. This is because of the special properties of borosilicate glass 3.3 and PTFE together with the special materials that are used in some instances for internals, plus the fact that borosilicate glass 3.3 is an approved and proven material of construction for pressure vessels

  • Being inert, the risk of contamination is negligible.
  • Their transparency permits constant visual monitoring of the process at all times.
  • With almost universal resistance to corrosion, a long service life is guaranteed and maintenance is kept to a minimum.
  • Smooth surfaces allow easy cleaning and sterilization and prevent the build-up of solids on the inner walls.

Column Components

All column sections are supplied complete with support. The packing must be ordered separately. On special request column sections can be supplied without the packing support. Column sections and pipe sections may be used for the construction of columns of all nominal bores provided that the weight of the packing and retained liquid does not exceed the load-bearing capacity of the support. Column section can also be provided with a thermometer branch below the packing support.

Packing support is supplied as part of the column section assembly, it is normally only ordered separately when replacements are required. The PTFE ring on which it is seated is supplied complete with the support

Standard packing support for columns DN 80 to DN 300 is manufactured from borosilicate glass. From DN 400 and above, a combination of glass and PTFE is used for it is construction, thus maintaining maximum resistance to corrosion.

There are two types of packing supports, Type A and Type B. Type A are made of fused glass rods and Type B (heavy duty) are made of glass plates, vertically arranged and tied with PTFE tie rods.

If the free cross-sections obtained with the combination of column sections and packing supports are not large enough, then an alternative is to use type APS pipe sections in combination with fixed support plates.

Each item comprises the glass supports plate, screwed rod with nuts, flat washers and compression springs and the special backing flange required for the assembly.

  • Due to their low bulk densities, glass rasching rings are particularly suitable for packing glass columns.
  • 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.
  • In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage other parts. To prevent this, a packing retainer (PTFE Performance Plates) should be used above the packed section

Packing retainer is installed above packed column section to prevent any carry-over of column packing. It is installed in the same way as gaskets between two flat buttress end faces and therefore no gasket is required. Packing retainer is manufactured from PTFE for maximum resistance to corrosion. It cannot be used as packing support.

Column feed pipe is designed for applications in which there is a need to introduce the process liquid at a single point. It is usually installed via a type APTU unequal tee piece (see Chapter 2 of this catalogue - Pipeline Components) and have a fused -in distribution tube which directs the fluid down onto the center of the column packing.

Column feed pipe for columns up to DN 600 is manufactured from borosilicate glass. Two types of column feed pipes are available.

In this component, the reflux is adjusted by means of a valve on the outlet connection. When the valve is fully open the divider is set to total distillate off-take, since the reflux pipe is higher than the outlet connection. By regulating the valve, the reflux ratio can be continuously adjusted up to total reflux.

This type of reflux divider uses a swinging funnel mechanism. The funnel, which has a soft iron core sealed into it, is operated magnetically from outside the column , so that the condensate can be removed from the column and reflux returned to the column in correct ratio. Activation of the electro-magnet moves the funnel into the off-take position. The electro-magnet and timer should be ordered separately. Main nozzel (DN2) is provided for ARHM 9 and above sizes.

Electro-magnet is used to operate magnetically operated Reflux dividers. When 'On' the magnet attracts the swinging funnel of the reflux divider so that distillate can be taken off.

Electro-magnets are to be mounted outside the glass column, just near to the reflux divider,with the help of adjustable fittings. This is designed to use with Timers to maintain correct ration between 'Off' and 'On' timings of its activation.

Electro-magnet work on 220V DC power supply, for which an output socket is provided in the Timer.

Timer is designed to use with Electro-magnets to provide a correct ratio of reflux and distillate when operating a Magnetically operated reflux divider.

Two independent knobs are provided for time settings of Reflux and Off-take. During 'Offtake' it activates the electro-magnet, which attracts the swinging funnel of reflux divider, and distillation comes out. Both periods can be set accurately within a range of 0-50 seconds.

Timer work on a power supply of 230V, 50Hz.
