SUPPLYING HIGH-PRESSURE PRIMARY ISOLATION VALVES AND PRESSURE CONTROL TECHNOLOGIES ENABLING THE SUPPLY OF HYDROGEN TO HYDROGEN FUELING STATIONS

CHALLENGE
Our client, a supplier of Hydrogen Trailers required valves qualified in accordance with the latest European Transportable Pressure Equipment Directive, a requirement for all valves used to isolate transportable hydrogen storage modules. The valves were required to be used at pressures up to 700 bar(g), at temperatures as low as -40°C with very tight limits on leakage. Without valves qualified to this standard, the trailer could not be certified and put into operation.

SOLUTION
CIRCOR engineers work diligently to establish a valve capable of meeting these highly demanding requirements. The ASV Series Pneumatically Actuated Stop Valve Series is based on CIRCOR’s highly reliable balanced valve concept but includes sealing technologies capable of performing across the range of pressures temperatures and leak rates required setting a new standard for high-pressure balanced valve design.

CIRCOR IS YOUR PARTNER
CIRCOR has a broad range of pressure and flow control components for Hydrogen Storage applications including Manual Stop Valves, Regulators, Slam Shut Valves, Residual Pressure Valves, Check Valves, and Filters, and can build complete Trailer Fill Cabinets for its clients –saving space, cost, and client engineering resources.

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

CHALLENGE
A leading supplier of Synchronous Condensers secured a turnkey project for its Synchronous Condensers 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.

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 underwent factory acceptance testing at our facility in Uxbridge, UK, and commissioning assistance was provided at the client site to ensure the successful functioning of the system.
