• Chemicals companies are exposed to high energy cost -> need for

efficiency increase and driving operational excellence

• Emission reduction regulations -> need for new solutions to achieve

high performance

• development of energy-efficient technologies, renewable sourced

material processing increases -> need for new materials withstanding

those operation conditions is emerging

Market Trends

• Reduce our dependence on fossil fuels

• Reduce the CO2 emission (less greenhouse effect)

• Focus on renewable energy sourced fuels

• Use of oxygen-containing fuels & Biodiesel that are more aggressive

���� Ethanol

� E6 & E85 in favor in California, E10 & E85 in rest of USA

� E10 in Europe, India and China

���� Oxygenates

� MTBE has been legislated out in the USA, but still used in Europe

� ETBE and Methanol as well

���� Biodiesel (B5 to B20)

� Improves diesel fuel emissions

� bio-degradable and non-toxic product

� Reduces diesel engine wear (inherent lubricity of FAME’s)

� Display excellent resistance to

aggressive biodiesel.

� Adequate sealing capability at low

temperatures

.

For excellent compatibility with fresh and aggressive contaminated

Biodiesels, peroxide cured Viton® types with no metal oxides are

recommended. .

Viton® F, GF-S

The Standard for Bioalcohols.

• low volume swell in bioalcohols (e.g. bioethanol and biobutanol)

5/20/2010

13

• Biofuel Production

• Process fluids involve fuel, raw ingredients (bio-oil, methanol), catalysts (bases)

• Ambient (as low as -40ºC) to 100ºC thermal range

• Pumps, valves, mechanical seals, flow meters, hoses, plate heat exchanger gaskets, filtration

systems

• Biofuel Storage

• Storage tanks – above and under ground with 0ºC to 30ºC thermal range

• Biodiesel stability limited to 6 months before use

• Biofuel Distribution

• Marine, rail and road

• Biofuel Blending

• Metering of diverse ingredients: flow meters, hoses

• Biofuel Dispensing• Flow meters, pumps, and dispensing units

Explosive

Decompression

Explosive Decompression (ED), also known as Rapid Gas Decompression

(RGD), is structural failure in the form of blistering, internal cracking and/or splitting

caused when the gas pressure to which the seal is exposed is reduced faster than the

gas can diffuse out of the part. This causes internal stresses in the part that can

exceed the physical strength limits of the elastomer.

Rapid Gas Decompression

Testing in 100% CO2 environment may be done in our lab at ETC Meyrin, Geneva
