Are
you facing:
 |
Production
bottlenecks in distillation columns
due to thermal or hydraulic constraints?
|
|
High
energy costs? |
|
Integration
of a new column into an existing process?
|
 If
so, the application of our specialised Column
Targeting techniques will improve your distillation
column operation.
With
years of experience our technology consistently
achieves significant operating and capital
cost savings.

5%
to 54% savings in energy |
|
3%
to 32% increase in throughput |
Column
Targeting is widely used in the chemical,
petrochemical and oil refining industries
for distillation column analysis. For both
new designs and retrofits, it focuses on
the lowest cost, short term options to:
|
Save
energy |
|
Reduce
cost of debottlenecking |
|
Reduce
required investment for expansion |
The
traditional approach in distillation column
analysis is to develop a simulation model
and then run a number of case studies to
explore the effect of different design and
operating parameters. Depending on the complexity
of the column, an exhaustive investigation
can be time consuming.
Our
approach is different. We take a single
converged simulation and from this we produce
energy flow and hydraulic profiles throughout
the column.
The
profiles highlight the potential for increasing
column efficiency and hydraulic performance
and at the same time indicate appropriate
improvements.
Column
Targeting is used explicitly to debottleneck
a process. For example, if the throughput
in a refinery crude distillation unit is
limited by the capacity of the fired heater,
a column analysis will allow you to evaluate
options for recovering additional heat from
the column. Analysis of the process will
then tell you whether this heat can be used
for additional preheat to avoid expensive
investment to the fired heater.
In
other cases the column itself may be the
bottleneck. Column Targeting then combines
thermal analysis with hydraulic analysis
and will pinpoint potential for increasing
throughput at minimal capital expense.
