Diffusion-bonded heat exchangers are highly compact, highly robust exchangers well established in the upstream, high pressure hydrocarbon processing, petrochemical and refining industries. 

With customers such as Statoil, BP, Shell and ExxonMobil, Heatric have delivered hundreds of PCHEs to projects all over the world and continue to provide heat exchange solutions for a wide range of new market sectors.

The PCHE is a preferred solution for Statoil’s gas compression cooling applications having established a long term frame agreement with Heatric. PCHEs provide a very good solution for LNG applications both with LNG production, revaporisation and dewpoint control.

Major Advantages:
Diffusion-bonded heat exchangers are four to six times smaller than conventional shell and tube heat exchangers of the equivalent duty.
They have a pressure capablity in excess of 600 bar (9000 psi) and can cope with extreme temperatures, ranging from cryogenic to 900°C (1650°F).

Diffusion-bonded exchangers can achieve high thermal effectiveness of over 98% in a single unit.

They can incorporate several process streams into a single unit. This design feature has space and weight advantages, reducing exchanger size together with piping and valve requirements.

Additional functions can be included in the exchanger design, such as chemical reaction, mass transfer and mixing, optimising the process considerably.

The compatibility of the chemical etching and diffusion-bonding process with a wide range of materials means that they are suitable for a range of corrosive and high purity streams.
