Celanese and Fortron® PPS Assist Bomat to Create First-of-Kind Heat Exchanger for Heating and Power Units

Press release date: October 16, 2013

Ingenious Polymer and Ceramic Combination Replaces Metal Components

Sulzbach, Germany, Florence, Ky., Shanghai – Celanese Corporation (NYSE: CE), the global technology and specialty materials company, is showcasing an innovative Bomat Profitherm heat exchanger with Fortron® polyphenylene sulfide (PPS) components at K 2013 in Düsseldorf, Germany.

High-temperature resistant Fortron PPS is used in both the complex water-carrying housing components (water distributor) and the side panels, while the heat exchange tubes are ceramic. This ingenious material combination enabled Bomat to produce a first-of-kind heat exchanger without any metal in the exhaust gas section.

Eliminating the high-alloy steels and aluminum from the exhaust gas section prevents the acidic flue gas condensate from dissolving any metal ions, especially heavy metal ions such as nickel and chromium. In every heating system, the flue gas condensate is discharged via the conventional waste water system, but this new technology prevents aluminum or heavy metal ions from entering the water cycle and damaging the environment. This means operators of heating systems and cogeneration heat and power plants (CHP) can obtain significantly more energy from their fuel and save natural resources, as well as reduce the environmental impact by decreasing the release of heavy metals.

Celanese was involved in the development of the new Bomat Profitherm heat exchanger from the beginning. Early involvement, which helped Bomat avoid unnecessary development loops and meet its ambitious timeline, focused on component design, supplemented by structure simulation and extensive calculation of mold filling, fiber alignment and weldline positions. In addition, extensive material and application knowledge, and technical support were an absolute pre-requisite.

As the material of choice for the innovative Bomat Profitherm heat exchanger, Fortron PPS provides:

Excellent resistance to the acidic flue gas condensates that arise in oil and gas burners and CHP
Very good resistance to heating oil and fuel gases
Outstanding heat distortion temperature
High strength and stiffness
Improves production of parts to the precision specified
Coefficient of linear thermal expansion similar to that of steel that, in combination with metal add-on pieces, results in lower thermal stress and forces acting on the components
Enables ready-to-use parts: Die-cut without any further reworking
More favorable overall energy balance than with customary metal cast parts; no mechanical reworking or corrosion protection required
Considerably lower component weights that simplify storage, transport and assembly
Possibility to use less expensive plastic direct screw fittings without the need for inserts

Eric Folz, Celanese design engineer, explains: "Increasing energy efficiency and saving resources — these are substantial contributions to a livable future. We are pleased we were able to help BOMAT in this new application. Bomat has been committed to these goals for more than 20 years and trusts in the efficiency of our polymers."
