4 Heatric leading the way in heat transfer engineering Thanks to a unique design and manufacturing process, Heatric compact diffusion-bonded heat exchangers are right at the forefront of heat transfer engineering. Not only can they attain temperatures and pressures beyond the reach of other compact exchangers, they outperform conventional shell and tube exchangers on virtually every level. Just take a look at the benefits: up to 85% smaller and lighter than an equivalent shell and tube exchanger pressure capability of over 600 bar (9000 psi) high thermal effectiveness of over 98% in a single unit extreme temperature capability, from cryogenic to C ( F) ability to cope with large temperature differentials between fluids and rapid temperature change able to incorporate multiple process streams into a single unit can achieve close temperature approaches (2 0 C) available in a range of corrosion resistant materials high integrity no gaskets (so no leaks), no braze and no tubesheets 3>4

Size matters Big isn t always better. In fact, when it comes to heat exchangers, small has very significant benefits.

Up to 85% smaller and lighter than an equivalent shell and tube exchanger, the Heatric product improves safety, reduces costs, makes installation easier and increases

They are installed, for example, in one of the modules that make up the International Space Station.

6 Size matters Big isn t always better. In fact, when it comes to heat exchangers, small has very significant benefits. That s why Heatric s compact diffusion-bonded heat exchangers are increasingly being specified by engineers across a range of industries. Up to 85% smaller and lighter than an equivalent shell and tube exchanger, the Heatric product improves safety, reduces costs, makes installation easier and increases process responsiveness. The compact nature of Heatric s exchangers is particularly suitable when space is limited and weight is critical. They are installed, for example, in one of the modules that make up the International Space Station. They are also ideal for retrofits because their compact design minimises modifications and enables greater capacity in the same space. The Heatric compact diffusion-bonded heat exchanger (weighing 15 tonnes) in the foreground performs the same thermal duty, at the same pressure drop, as the stack of three shell and tube exchangers (weighing 100 tonnes) behind. 5>6

Small but perfectly formed Every project is different, but the robust construction principles behind Heatric s exchangers are consistent for all applications.

As you would expect, Heatric is continually extending this list to meet emerging requirements.

Fluid contact can be counterflow, crossflow, co-flow or a combination of these to suit the process requirements.

8 Small but perfectly formed Every project is different, but the robust construction principles behind Heatric s exchangers are consistent for all applications. The needs of most of our clients are fulfilled by 300 series stainless steel. Other metals such as duplex stainless steel, titanium, nickel, nickel alloys and copper can also be used. As you would expect, Heatric is continually extending this list to meet emerging requirements. Fluid flow channels which can be of unlimited variety and complexity are chemically etched or pressed into flat metal plates. Fluid contact can be counterflow, crossflow, co-flow or a combination of these to suit the process requirements. The alternately-stacked plates are then diffusion-bonded to create a solid block of metal containing the fluid flow passages. The blocks are then welded together to form the complete heat exchange core. Finally, headers and nozzles are welded to the core to direct the fluids to the appropriate sets of passages. We were able to cut 3m off each deck, saving us $15m. 7>8 Richard Haugh, British Gas, Armada project

More bang for your buck Heatric compact diffusion-bonded heat exchangers can be configured to carry out multiple functions, reducing the need for separate plant.

This reduces costs and improves efficiency by combining the two operations of heating fuel gas and cooling lube oil.

For gas coolers this means a reduced coolant flow and smaller pipework requirements for the same cooling capacity as a shell and tube heat exchanger.

10 More bang for your buck Heatric compact diffusion-bonded heat exchangers can be configured to carry out multiple functions, reducing the need for separate plant. For example, Heatric exchangers have been used in gas turbine installations. This reduces costs and improves efficiency by combining the two operations of heating fuel gas and cooling lube oil. By using Heatric s diffusion-bonded heat exchangers, close temperature approaches and deep temperature crosses can be achieved in a single unit. For gas coolers this means a reduced coolant flow and smaller pipework requirements for the same cooling capacity as a shell and tube heat exchanger. The result is reduced capital cost and running costs throughout the life of the installation. Note that Heatric hardware is not restricted to heat exchange. It can also incorporate additional functions, such as chemical reaction, mass transfer and mixing. The other designs we evaluated needed multiple units and some compromise to our specification. Heatric proposed a single unit that met all our requirements. 9>10 Doug Webster, BASF, Geismar facility

The design also enables a fluid to be distributed passage-bypassage to mix with a process stream.

12 Three into one will go Heatric exchangers can integrate three or more process streams into a single unit. This multi-stream capacity offers further space and weight advantages through reduced exchanger and piping weight as well as simplifying process control. The design also enables a fluid to be distributed passage-bypassage to mix with a process stream. This distribution system has been successfully used for glycol injection into gas streams to prevent the formation of hydrates and can help deal with two-phase inlet streams where they occur. The construction of Heatric exchangers also allows meltable solids like waxes, hydrates and frozen glycol to be removed while still online. gas dehydration gas/ refrigerant gas gas/gas gas/ condensate condensate gas gas dehydration diffusion-bonded exchanger refrigerant We have more flexibility in module design and safer operation. 11>12 condensate Jerry Joynson, SBM Offshore

Safe and sound On safety and environmental fronts, Heatric compact diffusion-bonded heat exchangers offer significant benefits over conventional heat exchangers.

The potential for leakage and corrosion is significantly reduced because the heat exchangers have no gaskets or braze material.

14 Safe and sound On safety and environmental fronts, Heatric compact diffusion-bonded heat exchangers offer significant benefits over conventional heat exchangers. Heatric s solid diffusion-bonded core has first-class mechanical integrity. The potential for leakage and corrosion is significantly reduced because the heat exchangers have no gaskets or braze material. Neither are Heatric exchangers susceptible to the hazards commonly associated with shell and tube exchangers such as tube vibration and rupture. The elimination of the rupture hazard is a major consideration in reducing the size of overpressure relief systems. What s more, Heatric exchangers have a much smaller fluid hold-up than the equivalent shell and tube exchanger, reducing the inventory of hazardous fluids. They eliminated the need for a blowdown pressure relief system and significantly increased overall plant reliability. 13>14 Odd Knudsen, Statoil, Langeled gas receiving terminal
