What are hiTRAN® Thermal Systems?

What are hiTRAN® Thermal Systems?

For expansion retrofits or new reduced capital compact designs, hiTRAN® Thermal Systems are now widely recognised to substantially enhance the heat transfer performance of tubular heat exchangers.

So why should you consider implementing this increasingly popular technology?

The emergence of advanced heat exchanger designs and the adoption of enhancement technologies incorporated into traditional TEMA and API type exchangers are becoming more common as a means of reducing the capital and operating costs of new plants and extending the operating envelope of existing problematic exchangers.

In existing designs, Shell and Tube and Air-cooled heat exchangers frequently bottleneck output or limit the efficient performance of a process plant. When revamping and debottlenecking existing plants, the retrofit of heat transfer enhancement can lead to substantial benefits for minimal capital cost and rapid payback compared to the traditional alternative of revamping with a larger heat exchanger. This traditional alternative will naturally incur additional high capital costs during the commissioning phase (cutting pipework and implementing new ancillaries etc).

For new plants, the benefits of advanced heat exchanger technology are maximised if consideration is given during the conceptual process design phase.

hiTRAN Thermal Systems enhance radial mixing, increasing fluid shear stress at the tube wall; this reduces both boundary layer film resistances and extreme wall temperatures, providing benefits of increased thermal efficiency and advantages influences mitigating fouling in the right applications.

The technology is fast becoming the primary solution in an ever-expanding range of process applications where tube-side heat transfer is limited. Through an amalgamation of trusted engineering expertise, bespoke hiTRAN.SP software, and thousands of successful installations worldwide, we are confident that hiTRAN thermal and hydraulic performance can be predicted with certainty and offer clear operational benefits.

hiTRAN Thermal Systems technology can be implemented in a range of key heat exchanger applications which include:

  • Gas oil coolers
  • Benzene preheaters
  • Atmospheric/Vacuum residue exchangers
  • Ethane/butane vaporisers
  • Phenol coolers
  • Thermosiphon reboilers
  • Crude oil heaters
  • Sulfinol coolers
  • Polymer preheaters
  • Refrigerant boilers
  • Sulfolane reboilers
  • Glycol/TEG service exchangers


In addition, there are many other applications such as tube-side condensation of multi-component organic mixtures using hiTRAN thermal systems.

With the increasing pressure across the industry to reduce capital and operational costs why not see for yourself the impact of hiTRAN Thermal Systems technology free of charge, you may be surprised.
