Heat exchanger segment IFV


Low-quality seawater, Large capacity, Cold energy recovery..., making what you want possible

An intermediate fluid vaporizer (IFV) is an LNG vaporizer that can use even low-quality seawater as a heat source by using titanium tubes. The risk of freezing seawater is eliminated by using propane intermediate fluid. In addition, various cold energy recovery methods are available and have many successful experiences.


Sustainable use of LNG cold energy

  • Enable LNG vaporization and its cold energy recovery without creating CO2 emissions from combustion.
  • Enable cryogenic power generation by intermediate-fluid Rankine cycle.
  • Enable air conditioning and gas turbine intake air cooling by using industrial water as a heat medium.

Heat exchange process utilizing evaporation and condensation of intermediate fluid

Heat transfer tubes made of titanium prevent erosion and corrosion even in areas where seawater qualities are poor. 
 IFV is composed of three heat exchangers (E-1, E-2, and E-3) in one module.
 See the detailed structure illustration below.

After-Sales Service

Upon the customer's request, we dispatch experienced supervisors around the world to provide advisory services for installation and pre-commissioning.
Basically, the recommended maintenance is only jet water cleaning of the seawater system every year, and it can be easily handled by users.
