Waste Heat Recovery Units (WHRU)

WHRUs are engineered to recover waste heat from the exhaust of gas turbines or reciprocating engines. The heating media could be water, glycol mixture, thermal oil or water depending on the application.

Over 165 installations for the upstream oil and gas segment across diverse locations such as Sakhalin Island, Asian Offshore Waters, North SEA, African Offshore and the Americas

We have built a number of heat recovery units downstream of gas turbines, gas engines/oil fired engines.  The heat recovery units have been configured on engine size ranging upto 160 MW.

These units are installed on

  • Offshore platforms
  • Floating LNG
  • Floating production storage and offloading vessels (FPSO)
  • Onshore gas processing plants

Manufactured as per Technology developed by Thermax

TBWES offers the unique option of specially designed integral bypass systems. This system offers special features
such as:

  • Compact space saving design
  • Integral bypass facility
  • Online isolation of WHRU
  • Single stack option
  • Removable tube bundle
  • Optimum gas side pressure loss
  • Supplementary fired units with and without FAF

These units are very compact so that the footprint is less. The units are of removable type design often preferred for such applications.
