Fouling mitigation

• Turbotal

Spirelf
- Both devices are on-line mechanical cleaning
devices, aiming at reduction of the tube-side
fouling layer through mechanical effets
(vibration, in case of Spirelf rotation in case
of Turbotal(R). Also, inner heat transfer rate
increased by turbulence. - Typical applications
Crude Preheat Train, hydrotreaters,
feed-effluent exchangers
Heat Transfer enhancement
Fixotal
- Fixotal is a wall turbulence promoter, with
swirl effect. This fixed device is aimed
primarily at increasing heat transfer rate. It
also reduces fouling for wall temperature
dependant type of fouling (polymerisation,
solidification of wax, water scaling,) - Typical
applications Air coolers, Cooling water (test),
U-tubes, mixed-phase flow
