CASE STUDY – HYDROGEN, CO2, AND LP AIR SYSTEM DESIGNED FOR A COOLING APPLICATION ON ONE OF THE LONGEST POWER TRANSMISSION PROJECTS IN THE WORLD.

THE CHALLENGE
A leading supplier of Synchronous Condensers secured a turnkey project and needed hydrogen gas supply systems to charge the condensers’ cooling systems. The prime safety concern for the system was ensuring it could be purged in and out of service without hydrogen mixing with air as this would create an explosive mixture. As such, CIRCOR was contracted with designing a system that could be safely charged with hydrogen, monitored during operation, then, when required, could be safely purged of hydrogen, bringing the condenser to a safe state where maintenance activity could be undertaken prior to re-commissioning the system back to use.

THE SOLUTION
CIRCOR system designers worked with the client to establish a process design that would use CO2 to purge hydrogen from the condenser and then use air to purge CO2 from the condenser, making it safe to maintain. A gas delivery system was designed and built to take cylinder storage pressure down to injection pressure with an integrated heater system to ensure the gas delivery temperature was maintained at the correct level. A compressor system was utilized to supply air, and a Gas Distribution panel (right) was used to charge, vent, and continuously analyze the gas. All pressure control equipment utilized CIRCOR pressure regulators, valves, filters, and pressure relief devices. The whole system was factory acceptance testing at our facility in Uxbridge, UK. Commissioning assistance was provided at the client site to ensure successful setting to work of the system.
