Innovative high temperature sealing solution for supercritical CO2 power cycle
Project Lead: John Crane UK Limited
Supercritical carbon dioxide power cycles are a novel process currently under consideration across the energy sector, including for carbon capture, usage and storage (CCUS). Compared with conventional steam-driven systems, they boast higher cycle efficiencies, reduced emissions and compact turbomachinery, resulting in reduced fuel and water consumption and lower capital expenditures. In this project John Crane developed an innovative, uncooled high-temperature dry gas seal solution for these applications using new simulations, material compositions and testing validation to operate at high temperatures and pressure values, with the potential to significantly reduce leakages and potentially even enable the inclusion of an additional turbine expansion stage.
