Column Components

In many operations like reaction, extraction & absorption, the transparency of glass is particular advantage. For such process a range of column components are available in Borosilicate glass which offers many advantages like:

  • Inert to almost all chemicals hence no risk of contamination.
  • Transparency allows visual monitoring of the process flow patterns, colour changes etc.
  • Almost universal resistance to corrosion
  • Smooth surface permits easy cleaning & prevents fouling.

Column Components

Column sections – side view and cross section with dimensions DN, L, L1, d
Column can be constructed either by using pipe sections with support plates or using column sections with packing supports. Column sections are provided with fused shelf where packing support can rest.

Support plate assembly – top view and side view with packing, dimensions DN, L
Support Plate Assembly can be coupled with a pipe section (PS), so as to use the pipe section as a column section and to fill packings into it. This system provides following advantages over the conventional system of using column section with a packing support:

Higher cross section area
More packing height.
No separate inventory of column sections.
Delivery period of pipe section are shorter.

This assembly consist of a glass support plate, a metal flange, a PTFE 'O' ring and nut-bolts.

Notes of use of Column Packing:
Due to their low bulk densities, Glass Raschig 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 to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
Glass Raschig rings – column packing
Raschig rings upto 25mm are also available in Neutral glass. 20mm, 30mm, 40mm and 50mm are available in Borosilicate glass 3.3.

PACKING SUPPORT

Surya introduce single piece column section with inbuilt packing support.

Advantages of this column against conventional column section:
• Ease in installation being a single piece instead of two pieces
• There is no need to maintain stock of CS and packing support
• Increases effective packed height which results in to increase in efficiency.
• Zero maintenance against column flooding.

Electro-magnet and Timer with reflux divider – wiring and power supply
Electro-magnets are 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. These are designed to use with Timers to maintain correct ratio between 'Off' and 'On' timings of its activation.

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