The new zero-emission mechanical seal from EagleBurgmann prevents the emission of the greenhouse gas methane during natural gas extraction, transport and processing.
Natural gas is transported in pipelines over many thousands of kilometers to destinations around the globe, both overland and via the seabed. The flow of gas must be prevented from ebbing and drying up. Every now and again, giant compressors, like springs, with the power of about 100 car engines provide the necessary boost. But in the process, methane gas escapes. Until now, at least. The recently developed zero-emission mechanical seal, CobaDGS, from Freudenberg’s EagleBurgmann Business Group uses nitrogen to prevent these harmful emissions. The sealing innovation makes a sustainable contribution to curbing global warming.
