| Column internals System accessories for Montz packings |
 |

|
The
range of products offered by Montz is rounded off by special internals.
A perfect perfomance can thus be achieved with a fully integrated
program. |
|||
|
|
|||
Flash-boxesFlash-boxes
are always installed at a column feeding point, when the inlet is
overheated. Flash vapour may occur after entering into the column,
which can affect the good functioning of the liquid distributor. |
|
||
|
|
|||
Flash-box Type IN
|
 |
||
| Flash-box Type IN has been designed for smaller amounts of flash vapour occurring at overheated inlets. This type of flash-box can be installed inside the column near the inlet. Flash-box Type IN is suitable for columns with a diameter from approx. 900 mm. | |||
 |
|
||
Flash-box Type A
|
 |
||
|
Flash-box
Type A has been designed for higher evaporation rates. It is installed
outside the column near the columnfeeding point: the overheated feed
enters the box via a nozzle and is reduced tocolumn pressure inside the
box. The flashvapour generated escapes through an misteliminator on top
of the flash-box and is feed to the column through a piping system.The
residual liquid is drained from the bottom at the box and flows to the
feed nozzle of the column.

|
||
Support system Type G
|
 |
||
|
Support
systems serve as support for the structured packings. The support
system Type G is suitable for columns of a diameter of <1000 mm. Two
or more beams bridge the cross-section of the column. These main beams
hold the greast rods on to which the packing is placed. It is designed
so that all parts can be installed through manholes.
|
|||
|
|
||
Support system Type K
|
|
||
|
The
support system Type K for columns of a diameter of <1000 mm is of a
one-piece design and is installed in the column through a shell flange
connection. For diameters up to approx. 2500 mm the support system is
of mulitsectional design and is installed through manholes. Cams on the
column wall serve as a support and for fixation.

|||
|
|
||
Liquid collector
|
 |
||
|
Liquid collector trays are arranged between two packing sections. Thus, the liquid trickling down is collected by the liquid collector tray and from here it can be returned to a liquid distributor. In the vicinity of the liquid collector tray it is possible to install liquid/vapour feeds or liquid/vapour draw offs. |
|||
|
|
||
Vapour distributor
|
 |
||
|
Gas or vapour disrtibutors are used to achieve a uniform gas flow across the diameter of the column. The use of vapour distributors is recommended in the case of low vapour velocities and if distances between vapour inlet nozzles and packing are too small. |
