The Phoenix Group has a long standing association with many landfill and biomass plants in the UK, providing Leak Detection and Repair (LDAR) services and supplying gaskets and other sealing products.
One of these sites is a waste treatment facility in the central belt of Scotland which converts landfill gas to usable energy. This process involves extracting gas (methane), which is processed and pumped to gen set engines within a turbine house. These engines generate electricity, which is sold to the national grid.
The process is volatile, with process temperatures that operate beyond the limits of traditional gasket materials such as compressed fibre and graphite. Previous attempts to find a suitable gasket had failed, with the products failing before the engines could next be serviced.
Phoenix sealing were asked to offer a high temperature sealing solution for inlet and outlet flanges of the engine exhaust system that would offer long term, high integrity sealing. PG-Therm, a mica (phlogopite) based sealing material was offered, and successfully installed, adding approximately 300hrs extra running time between services with zero leakage.
