Tru-Scan® - Trayed Column Application
- Verify tray placement
- Determine missing or damaged trays
- Evaluate tray froth heights and liquid levels in downcomers
- Detect mechanical, rate and process related problems
- Reduce operating costs and shutdown time
Damaged or missing trays, plugged downcomers, feed problems,
and tray fouling are examples of problems with columns that
can be diagnosed with a TRU-SCAN®. One scanline taken
through the active tray deck (bubbling area) is normally
sufficient for diagnosing many operating problems.
A TRU-SCAN® is used to evaluate the mechanical integrity
and hydraulic performance of trayed columns by measuring
froth levels on tray decks, liquid backup in downcomers,
and clarity of liquid/vapor disengagement zones.
Mechanical Problems - A TRU-SCAN® can provide
an on-line inspection for column internals. Partial tray
damage, buckled or missing tray manways, and severely fouled
trays are examples of physical problems that can be detected
from scan results.
Rate Related Problems - Weeping, entrainment, and
tray flooding often result from design limitations, physical
problems, or a combination of these. A TRU-SCAN® can
detect each of these problems.
Process Related Problems - Scans can be very helpful
in debottlenecking or economizing one or more columns in
an operating unit. Performance stabilization will result
in extended run times and lower maintenance costs.
TRU-SCAN® technology has a proven track record in
assisting with plant start-ups, pre-shutdown planning and
operational troubleshooting. The scan results are produced
from the tangent to tangent height and can be performed
through active areas at different operating rates. Scanline
plots can be overlaid to show a comparison of results.
A history of tower scanlines can also be overlaid to compare
past and present tower scan results. We have an extensive
database of projects undertaken and reference lists of companies
that have used TRU-SCAN® technology can be supplied
on request.
