Thanks to its portfolio of technologies and industrial and operational assets, Technip offersa unique vertically integrated model in the industry. The Group has 3 flexible pipe manufacturing plants, 4 umbilical production units, 9 logistics and pipeline assembly bases, and1 construction yard. Technip’s worldwide leadership is supported by a modern fleet of vessels for subsea construction, pipelaydevelopment (rigid and flexible pipes using S-Lay, J-Lay or Reeled technology) and heavy lift applications.

Offshore: In the Offshore business segment Technip performs engineering, procurement, construction, installation, commissioningand the refurbishment/upgrading of offshore facilities for the oil & gas industry.Technip provides these services for fixed platforms in shallow water with conventional sub-structures and self installing platformssuch as the TPG 500 and for deepwater facilities including Spar, semi-submersible, TLP, FPSO and FLNG units. Technip is a worldleader in floatover installation of topsides and its R&D effort is focused on technology transfer for local content and new frontierareas such as ultra-deepwater and the Arctic.

Onshore: Technip covers the full range of onshore facilities for the oil and gas chain, petrochemicals and other energy industries(nuclear, renewables including biofuels and offshore wind). It holds many proprietary cutting-edge technologies and is the leader inthe design and construction of LNG and gas treatment plants as well as ethylene, hydrogen and syngas units.Technip is also one of the key actors in refining and petrochemical units, and has developed a leadership in the fertilizer industry.Moreover, the Group is very active in non-energy activities such as mining and metals, life sciences, buildings and infrastructures.

3Enhanced heat transfer solutions

The enhanced heat transfer solutions developedby Technip and Wieland provide improved energyefficiency and substantial savings to Ethylene andLiquefied Natural Gas (LNG) plants.

Complementary expertise from twoindustry leaders

Further work packages concentrated on enhancedtubeside heat transfer and pressure drop performance insingle-phase gas and liquid services as well as two-phase /condensation.

This created a solid design basis allowing compact andefficient enhanced heat exchanger designs.

More than 50 large heat exchangers inoperation

This long-term collaborative effort together withindustrial references established since 2000 in thepetrochemical and LNG industries contributes to makingTechnip-Wieland heat exchangers standard equipment inlarge capacity ethylene and LNG plants.

In addition, more than 50 heat exchangers are underconstruction for Technip or Third Party Projects.For Third Party Projects heat exchangers are based onTechnip design.

Two product lines

Technip and Wieland offer two main products:GEWA-PB enhanced boiling tubesGEWA-KS enhanced condensing tubes

Heat exchange is a pivotal unit operation in most

industrial processes: refining, ethylene, gas treatment and

liquefaction to name a few. The most frequently

encountered technologies are shell-and-tube, air cooled

and miscellaneous compact heat exchangers.

Technip-Wieland's enhanced heat transfer solutions for

shell-and-tube technology provide substantial savings and

environmental benefits through:

reduced investment and operating costs

higher productivity and improved energy efficiency by

either reducing the size of the units or the temperature

approach and/or increasing its thermal performance

reduced CO2 emissions

An agreement based on long-termcollaboration and R&D efforts

In November 2007, Technip and Wieland entered into a

formal agreement to jointly market innovative heat

exchangers.

This agreement followed 10 years of collaboration

between these two groups to qualify dual enhanced

tubes with the aim of becoming a hydrocarbon

processing industry standard especially for large shell-and-

tube heat exchangers for grassroots LNG and ethylene

plants.

Starting in 1996, a joint academia-industry R&D program

funded by the European Union was formed establishing

heat transfer and thermal design information for enhanced

horizontal shellside nucleate boiling with light

hydrocarbons, primarily propane.

Ethylene production

Applications using GEWA-KS tubes

Applications using GEWA-PB tubes

Minimising energy consumption is a goal that our Clientsare continually pursuing.

In Ethylene mega-crackers, reductions in energyconsumption have so far been obtained through betterfurnace thermal efficiency and reduced compressionpower per tonne of ethylene that in turn affects steamdemand.

Technip-Wieland’s enhanced heat exchangers allowfurther reduction in energy consumption and CO2

emissions.

The technology we have developedcontributes to energy and CO2

emission reduction in both boilingand condensing applications.

Cost-savings

Compared to solutions with traditional plain and low-finned tubes, Technip-Wieland products contribute to aclear cost saving in the cost of an Ethylene cracker.

Increasing LNG production per unit ofrefrigerant compression power has been apermanent goal of LNG plant developers.

Technip-Wieland’s enhanced heat exchangersfor propane evaporation and condensationallow further increases in LNG production, oralternatively lower power consumption andCO2 emissions.

Considering LNG plant debottlenecking?

Change-out of a plain or low-finned tube bundle for GEWA-PB tubes in an existing plant will increase LNG productionwith no change in power consumption.

GEWA-KS tubes, in a water cooled condenser, can bring further gains.

Ideal for grassroots LNG plants

The enhanced performance of ourexchangers provides end Clients withincreased LNG production for givenrefrigerant compression power.

6 Enhanced heat transfer solutions

GEWA-KS tubes

Equipment installed since Agreement signature. In addition to this references list, 1 heat exchanger is under construction.

Common to all applications are the advantages of more compact, cost effective and lighter heat exchangeequipment.

Beyond this, system improvements can be achieved with savings regarding refrigerant and process fluid chargesas well as piping racks, support structures and foundations.

Key references

GEWA-KS tubes have been implemented in some of the world's major facilities.

Propane condenser comparative study

GEWA-KS finned tubes with both externally and internallyenhanced surfaces are used in external condensingapplications such as air-conditioning and refrigeration aswell as the hydrocarbon processing industry.

7Enhanced heat transfer solutions

GEWA-PB tubes

Equipment installed since Agreement signature. In addition to this references list, more than 30 heat exchangers are under construction.

Key references

The GEWA-PB tubes have been implemented in some of the world's major Ethylene and LNG facilities.

Temperature approach

A cold-end temperature approach of 2°C (instead of 3°Cwith low-finned tubes) leads to increased LNGproduction.

Primary applications are clean processes such as in LNG and Olefin plants, as wellas refinery light-end sections, C2 and C3 refrigeration systems.

The GEWA-PB tube promotes very high thermal efficiency due to specialenhanced surfaces, and is suitable for boiling at small temperature differenceswhere standard tubes are no longer applicable.

Substantial benefits have been identified with regards to increased production ofLNG or savings in tube length and total heat exchanger weight.
