Internals Overview |
|
|
Sulzer's big experience in the
separation business allows to provide internals
for each combination of technology. Transitions
from structured packing sections to tray
sections, changes between different tray
sections or combination of separator-internals
are designed for optimized performing
columns.
Internals could be designed and
delivered for different materials; stainless
steel, titanium, several plastics and pure
carbon have been provided for many columns. The
worldwide implemented standard guarantees the
global quality in design and manufacturing of
internals.
Column internals are installed
on adjusted or on existing column attachments.
The requirements are carefully verified and
specified for each situation.

| Liquid Inlet
Systems |
|
|
Depending on the flow rate an
appropriate inlet system is recommended. We have
solutions either to feed separation trays or
liquid distributors.

| Liquid
Distributors |
|
|
Liquid distribution is crucial
for a proper running packed bed. Sulzer has a
wide variety of different liquid distributors
for different applications. For instance for use
in conjunction with:

|
|
|
| Collecting
Devices |
|
|
Liquid collectors including
packing support help to save column-height.
Optimized design of the collecting troughs
reduces pressure head in the collecting-section.
Chimney trays are provided to accumulate liquid
or to improve vapor distribution below packed
beds.

| Handling of
Flash-Feed |
|
|
Flash-feed is well separated in
its components before it is used for liquid
distribution or vapor feed. Every column has
different feed conditions which is carefully
considered in the design of the flash devices.

| Support
Devices |
|
|
Support systems for every
different packing type which can be easily
installed with a minimum of beams and welding
attachments.

|
| Vapor
Distribution |
|
|
The distribution of vapor is not
that critical than distribution of liquid. But
it is as well a challenge to handle and design
it for a correct operation. Our engineers know
how to do this correctly with a minimum of
installed parts for every kind of application.
