Columns are the core of any distillation plant. It is adapted to each
application by the design and selection of different column internals.
Column typesOur distillation & rectification systems, operating under vacuum, at
atmospheric condition, or in pressure, optimally use the following
column types, depending on the application:
Tray columns- Sieve tray
- Bubble cup tray
- Valve tray
- Tunnel tray
Packing columns- Random packing
- Structured packing
In
general, trays are used in applications with liquid flow-rate of 30
m3/m2h and above, and/or those where solids are present or fouling is a
concern.
Structured packing are typically used in lower flow-rate
applications, especially where minimizing column pressure drop is
important (e.g. under low vacuum).
Random packing are often used in higher flow-rate applications where lower pressure drop is desired.
Depending on the application, distillation columns are equipped with the following reboiler types:- Agitated Thin Film TFE/E
- Falling Film FFE
- Forced Circulation Reboilers
