CSP11 - Testing and Troubleshooting of Pump Dry Gas Seals Operating with sCO2

Abstract

During the testing of a 1 MWe power loop with super critical co2, it was discovered that dry ice formation across dry gas seals would be an issue. This case study looks at the negative effects of dry ice formation and how the problem can be prevented during loop transient operation, mainly during filling and steady hold conditions.
