Tube insert technologies
Partager sur :

TURBOTAL® is a rotating device hooked on a fixed head set on the tube sheet on the inlet side. This system converts the energy of the fluid flow in the tubes into rotation. This rotation provides a continuous online cleaning to reduce the fouling layer at the tube wall.

The heat transfer improvement leads to a significant increase either in outlet temperature or in feed rate.

The most common fluids used are atmospheric residue, crude oil, and most of the light liquid hydrocarbon chains operated in stabilized flow conditions. Applications are limited to liquid velocity between 1.0 m/s and 2.0 m/s (3.2ft/s and 6.4 ft/s).

This result in a proven increase in run duration (double or more) and a stabilized pressure drop.

Heat transfer increase

The turbulence generated by the presence of the insert increases the tube side heat transfer coefficient by 50% to 100%.

Energy savings and CO2 emissions

The improved heat recovery from the hot fluid results in a reduction in fired heater duty and consequently, a reduction in fuel consumption and consequently on CO2 emission.

Debottlenecking the preheat train

The furnace is the bottleneck when the throughput of the unit is constrained by the feed preheat. Improving the heat recovery of the preheat train increases the throughput up to 3% with the same preheat temperature.

On line mechanical cleaning, Reduction in fouling, Stabilized pressure drop

TURBOTAL® converts the tube side fluid energy into a mechanical cleaning of the inside tube wall through rotation.

The mechanical cleaning effect leads to a reduction in the fouling rates of up to 80%.

As the fouling rate is stabilized, the steady flow hydraulics leads to a stabilized pressure drop.

Run duration increased

Heat transfer improvement and fouling mitigation lead to doubled run duration and better operating conditions.
