With a heritage of serving the energy sector, Omniseal Solutions has consistently been working on sealing and material innovation by solving rising challenges in valve sealing operating conditions and enabling progress toward a carbon-neutral future. By leveraging decades of material science and design expertise acquired with valves for offshore deepwater production, cryogenic valves and low-fugitive emission valves, the company’ s technical experts are continuing to engineer advanced Omniseal ® polymer and metal sealing solutions to support decarbonisation. As the major source of global greenhouse gas emissions, the energy sector holds the key to respond to 2050 global net-zero ambitions. This requires a gradual shift away from fossil fuels and the implementation of technologies that enable the mitigation of emissions in hard-to-abate sectors. In order to deep cut emissions, green hydrogen and its derivatives as well as carbon capture, utilisation and storage( CCUS) are several viable options today that are being accelerated and pushed by public and private sectors who are injecting billions in funding projects. These low-carbon emitting technologies are pushing the boundaries of non-metallic sealing materials in different areas to cope with the needs of the engineered valves market:
• Gaseous hydrogen requires soft sealing materials with low permeation and resistance to rapid gas decompression to ensure leaktight performance
• Liquid hydrogen at 20 ° K up to 100MPa requires a unique set of soft sealing materials and designs
• Ammonia transfer requires soft-sealing materials with excellent chemical resistance and tribological properties
• Carbon dioxide requires soft-sealing materials with excellent chemical resistance when exposed to impurities and resistance to rapid gas decompression
To meet technological challenges posed by the new energy mix requires an in-depth knowledge of the industrial processes in place and how they impact the design of valves. Omniseal Solutions relies on its relationships with valve manufacturers as well as main EPC companies to anticipate new needs in highperformance sealing materials and solutions. Long-term collaboration combined with a strong investment in research and development in innovative fluoropolymer science result in precision sealing solutions that deliver enhanced durability, effective leak prevention and reliable performance. This strategic approach has also resulted in a major achievement their thermoplastic material certification, verifying that its material reduces its carbon footprint and successfully handles various critical challenges of decarbonisation.
