Column Components

Column Components | Couplings | Glass Joint | Heat Exchangers | Measurement & Control | Pipeline Components | Rotary Film Evaporator | Sight Glasses | Stirrers | Structure & Supports | Typical Units | Valves | Vessels

In many operations like reaction, extraction and absorption, the transparency of glass is a particular advantage. For such processes 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 and prevents fouling.

MEASUREMENT & CONTROLS

In this part we have introduced equipment for efficient measure and control like Digital temperature indicators and controllers, Electro-magnet and timers for reflux control and Liquid level controller.

COLUMN SECTIONS

Column can be constructed either by using pipe section with support plates or using Column Section with Packing supports.

Column sections are provided with fused shelf where packing support can rest.

SUPPORT PLATE ASSEMBLY

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 packing 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 ring 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 application 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.

PTFE SUPPORT PLATES

PTFE Support plates are sandwiched between two pipe sections to provide base to packing supports.

DN2 is used for insertion of a thermometer pocket. A bellow is recommended on the distillate outlet DN1.

Magnetically Operated

These reflux dividers are to be used with a electro-magnet and a timer. These have a swinging funnel mechanism which is operated magnetically from outside to remove the condensate or to return the reflux.

Through this correct control or reflux-ratio is possible. Funnel remains at 100% reflux position when magnet is inactive.
