Safety relief valves for hydrogen
Hydrogen is used for energy storage, as a raw material in industrial processes and as an energy carrier. Hydrogen production, storage, transport and use can involve high pressures and a wide range of process conditions. Reliable overpressure protection is therefore essential. A safety relief valve for hydrogen protects installations, piping and pressure equipment against excessive pressure. Hitma helps you select and size a safety relief valve that matches your hydrogen application and process conditions.
Overpressure protection in hydrogen systems
Safety relief valves can be used at various stages throughout the hydrogen value chain, including:
- hydrogen production
- compression and storage
- transport and distribution
- process installations where hydrogen is used as a raw material or process gas
- energy storage systems and Power-to-Gas applications
Hydrogen places specific demands on safety relief valves
Hydrogen is an extremely light gas with very small molecules. When selecting valves, safety relief valves and other components, it is therefore important to ensure that the materials and seals are suitable for hydrogen service.
Process conditions can also vary considerably between hydrogen applications. A safety relief valve may, for example, be exposed to very high pressures, cryogenic temperatures or situations where a large volume of gas needs to be discharged within a short period of time.
Selecting the right safety relief valve therefore involves more than considering connection size and operating pressure. Important parameters include:
- medium and composition
- operating pressure and set pressure
- temperature
- required discharge capacity
- back pressure
- connections
- material selection
- applicable standards and certifications
Based on these parameters, the appropriate valve configuration and sizing for the hydrogen system can be determined.
IMI Bopp & Reuther safety relief valves for hydrogen
Hitma represents IMI Bopp & Reuther safety relief valves. The product range includes various technological solutions for applications throughout the hydrogen value chain.
Sizing a safety relief valve for hydrogen
In an overpressure situation, a safety relief valve must have sufficient capacity to discharge the required amount of hydrogen. Selecting a valve based solely on the pipe diameter or maximum operating pressure is therefore not sufficient.
Hitma can select and size the appropriate safety relief valve for your application. We consider factors such as process conditions, pressure, temperature, required discharge capacity and the specific conditions in which the valve will be used.
For sizing and selecting IMI Bopp & Reuther safety relief valves, we use Si-Tech selection software.
This means you get more than just a safety relief valve that fits your piping: you get a solution selected according to the required discharge capacity and specific process conditions.
